How To Install Linux, Nginx, MySQL, PHP (LEMP stack) on Ubuntu 18.04

Introduction

                                                $ ssh root@ip
                                                $ sudo apt update
                                                $ sudo apt install nginx

                                $ sudo ufw enable
                                $ sudo ufw allow 'Nginx HTTP'
                                $ sudo ufw allow ssh
                                $ sudo ufw allow http
                                $ sudo ufw allow https

You can verify the change by running:

$ sudo ufw status

									Output
									status: active

										To                    Action            From
										--                    ------            ------
										openSSH               ALLOW             Anywhere
										Nginx HTTP            ALLOW             Anywhere
										OpenSSH (v6)          ALLOW             Anywhere (v6)
                                        Nginx HTTP (v6)       ALLOW             Anywhere (v6)

With the new firewall rule added, you can test if the server is up and running by accessing your server’s domain name or public IP address in your web browser.

If you do not have a domain name pointed at your server and you do not know your server’s public IP address, you can find it by running the following command:

$ ip addr show eth0 | grep inet | awk '{ print $2; }' | sed 's/\/.*$//'

This will print out a few IP addresses. You can try each of them in turn in your web browser.

As an alternative, you can check which IP address is accessible, as viewed from other locations on the internet:

$ curl -4 icanhazip.com

Type the address that you receive in your web browser and it will take you to Nginx’s default landing page:

http://server_domain_or_IP

If you see the above page, you have successfully installed Nginx.

Step 2 – Installing MySQL to Manage Site Data

Now that you have a web server, you need to install MySQL (a database management system) to store and manage the data for your site.

Install MySQL by typing:

$ sudo apt install mysql-server

The MySQL database software is now installed, but its configuration is not yet complete.

To secure the installation, MySQL comes with a script that will ask whether we want to modify some insecure defaults. Initiate the script by typing:

$ sudo mysql_secure_installation

This script will ask if you want to configure the VALIDATE PASSWORD PLUGIN.

Answer Y for yes, or anything else to continue without enabling.

							VALIDATE PASSWORD PLUGIN can be used to test passwords
							and improve security. It checks the strength of password
							and allows the users to set only those passwords which are
							secure enough. Would you like to setup VALIDATE PASSWORD plugin?
                            Press y|Y for Yes, any other key for No:

If you’ve enabled validation, the script will also ask you to select a level of password validation. Keep in mind that if you enter 2 – for the strongest level – you will receive errors when attempting to set any password which does not contain numbers, upper and lowercase letters, and special characters, or which is based on common dictionary words.

							There are three levels of password validation policy:
							LOW    Length >= 8
							MEDIUM Length >= 8, numeric, mixed case, and special characters
							STRONG Length >= 8, numeric, mixed case, special characters and dictionary
                            Please enter 0 = LOW, 1 = MEDIUM and 2 = STRONG: 1 

Next, you’ll be asked to submit and confirm a root password:

							Please set the password for root here.
							New password:
                            Re-enter new password: 

For the rest of the questions, you should press Y and hit the ENTER key at each prompt. This will remove some anonymous users and the test database, disable remote root logins, and load these new rules so that MySQL immediately respects the changes we have made.

Note that in Ubuntu systems running MySQL 5.7 (and later versions), the root MySQL user is set to authenticate using the auth_socket plugin by default rather than with a password. This allows for some greater security and usability in many cases, but it can also complicate things when you need to allow an external program (e.g., phpMyAdmin) to access the user.

If using the auth_socket plugin to access MySQL fits with your workflow, you can proceed to Step 3. If, however, you prefer to use a password when connecting to MySQL as root, you will need to switch its authentication method from auth_socket to mysql_native_password. To do this, open up the MySQL prompt from your terminal:

$ sudo mysql

Next, check which authentication method each of your MySQL user accounts use with the following command:

mysql> SELECT user,authentication_string,plugin,host FROM mysql.user;

							Output
							+------------------+-------------------------------------------+-----------------------+-----------+
							| user             | authentication_string                     | plugin                | host      |
							+------------------+-------------------------------------------+-----------------------+-----------+
							| root             |                                           | auth_socket           | localhost |
							| mysql.session    | *THISISNOTAVALIDPASSWORDTHATCANBEUSEDHERE | mysql_native_password | localhost |
							| mysql.sys        | *THISISNOTAVALIDPASSWORDTHATCANBEUSEDHERE | mysql_native_password | localhost |
							| debian-sys-maint | *CC744277A401A7D25BE1CA89AFF17BF607F876FF | mysql_native_password | localhost |
							+------------------+-------------------------------------------+-----------------------+-----------+
                            4 rows in set (0.00 sec)

In this example, you can see that the root user does in fact authenticate using the auth_socket plugin. To configure the root account to authenticate with a password, run the following ALTER USER command. Be sure to change password to a strong password of your choosing:

mysql> ALTER USER 'root'@'localhost' IDENTIFIED WITH mysql_native_password BY 'password';

Then, run FLUSH PRIVILEGES which tells the server to reload the grant tables and put your new changes into effect:

mysql> FLUSH PRIVILEGES;

Check the authentication methods employed by each of your users again to confirm that root no longer authenticates using the auth_socket plugin:

mysql> SELECT user,authentication_string,plugin,host FROM mysql.user;

							Output
							+------------------+-------------------------------------------+-----------------------+-----------+
							| user             | authentication_string                     | plugin                | host      |
							+------------------+-------------------------------------------+-----------------------+-----------+
							| root             | *3636DACC8616D997782ADD0839F92C1571D6D78F | mysql_native_password | localhost |
							| mysql.session    | *THISISNOTAVALIDPASSWORDTHATCANBEUSEDHERE | mysql_native_password | localhost |
							| mysql.sys        | *THISISNOTAVALIDPASSWORDTHATCANBEUSEDHERE | mysql_native_password | localhost |
							| debian-sys-maint | *CC744277A401A7D25BE1CA89AFF17BF607F876FF | mysql_native_password | localhost |
							+------------------+-------------------------------------------+-----------------------+-----------+
                            4 rows in set (0.00 sec)

You can see in this example output that the root MySQL user now authenticates using a password. Once you confirm this on your own server, you can exit the MySQL shell:

mysql> exit

							Note: After configuring your root MySQL user to authenticate with a password, you’ll no longer be able to access MySQL with the sudo mysql command used previously. Instead, you must run the following:
							$ mysql -u root -p
                            After entering the password you just set, you will see the MySQL prompt.

At this point, your database system is now set up and you can move on to installing PHP.

Step 3 – Installing PHP and Configuring Nginx to Use the PHP Processor

You now have Nginx installed to serve your pages and MySQL installed to store and manage your data. However, you still don’t have anything that can generate dynamic content. This is where PHP comes into play.

Since Nginx does not contain native PHP processing like some other web servers, you will need to install php-fpm, which stands for “fastCGI process manager”. We will tell Nginx to pass PHP requests to this software for processing.

$ sudo add-apt-repository universe

Install the php-fpm module along with an additional helper package, php-mysql, which will allow PHP to communicate with your database backend. The installation will pull in the necessary PHP core files. Do this by typing:

$ sudo apt install php-fpm php-mysql

You now have all of the required LEMP stack components installed, but you still need to make a few configuration changes in order to tell Nginx to use the PHP processor for dynamic content.

This is done on the server block level (server blocks are similar to Apache’s virtual hosts). To do this, open a new server block configuration file within the /etc/nginx/sites-available/ directory. In this example, the new server block configuration file is named example.com, which you need to replace with your domain name of your choice.

$ sudo nano /etc/nginx/sites-available/example.com

By editing a new server block configuration file, rather than editing the default one, you’ll be able to easily restore the default configuration if you ever need to.

Add the following content, which was taken and slightly modified from the default server block configuration file, to your new server block configuration file:

							server {
									listen 80;
									root /var/www/html;
									index index.php index.html index.htm index.nginx-debian.html;
									server_name example.com www.example.com;
									location / {
										try_files $uri $uri/ /index.php?/$request_uri;
								}
								location ~ \.php$ {
											include snippets/fastcgi-php.conf;
											fastcgi_pass unix:/var/run/php/php7.2-fpm.sock;
								}
								location ~ /\.ht {
											deny all;
								}
                            }

Please use the correct PHP Version number above based on your operating system on teh server. For example for Ubuntu 20.04 PHP version should be 7.4 instead of 7.2 in the file above.

Here’s what each of these directives and location blocks do:

After adding this content, save and close the file. Enable your new server block by creating a symbolic link from your new server block configuration file (in the /etc/nginx/sites-available/ directory) to the /etc/nginx/sites-enabled/ directory:

$ sudo ln -s /etc/nginx/sites-available/example.com /etc/nginx/sites-enabled/

Then, unlink the default configuration file from the /sites-enabled/ directory:

$ sudo unlink /etc/nginx/sites-enabled/default

$ sudo ln -s /etc/nginx/sites-available/default /etc/nginx/sites-enabled/

Test your new configuration file for syntax errors by typing:

$ sudo nginx -t

If any errors are reported, go back and recheck your file before continuing.

When you are ready, reload Nginx to make the necessary changes:

$ sudo systemctl reload nginx

This concludes the installation and configuration of your LEMP stack. However, it’s prudent to confirm that all of the components can communicate with one another.

Step 4 – Creating a PHP File to Test Configuration

Your LEMP stack should now be completely set up. You can test it to validate that Nginx can correctly hand .php files off to the PHP processor.

To do this, use your text editor to create a test PHP file called info.php in your document root:

$ sudo nano /var/www/html/info.php

Enter the following lines into the new file. This is valid PHP code that will return information about your server:

                            /var/www/html/info.php
                            
                        

When you are finished, save and close the file.

Now, you can visit this page in your web browser by visiting your server’s domain name or public IP address followed by /info.php:

http://your_server_domain_or_IP/info.php

You should see a web page that has been generated by PHP with information about your server:

If you see a page that looks like this, you’ve set up PHP processing with Nginx successfully.

After verifying that Nginx renders the page correctly, it’s best to remove the file you created as it can actually give unauthorized users some hints about your configuration that may help them try to break in. You can always regenerate this file if you need it later.

For now, remove the file by typing:

$ sudo rm /var/www/html/info.php

With that, you now have a fully-configured and functioning LEMP stack on your Ubuntu 18.04 server.

Conclusion

A LEMP stack is a powerful platform that will allow you to set up and serve nearly any website or application from your server.

There are a number of next steps you could take from here. For example, you should ensure that connections to your server are secured. To this end, you could secure your Nginx installation with Let’s Encrypt. By following this guide, you will acquire a free TLS/SSL certificate for your server, allowing it to serve content over HTTPS.

Using Free Let’s Encrypt SSL/TLS Certificates with NGINX

It’s well known that SSL/TLS encryption of your website leads to higher search rankings and better security for your users. However, there are a number of barriers that have prevented website owners from adopting SSL.

Two of the biggest barriers have been the cost and the manual processes involved in getting a certificate. But now, with Let’s Encrypt, they are no longer a concern. Let’s Encrypt makes SSL/TLS encryption freely available to everyone.

Let’s Encrypt is a free, automated, and open certificate authority (CA). Yes, that’s right: SSL/TLS certificates for free. Certificates issued by Let’s Encrypt are trusted by most browsers today, including older browsers such as Internet Explorer on Windows XP SP3. In addition, Let’s Encrypt fully automates both issuing and renewing of certificates.

In this blog post, we cover how to use the Let’s Encrypt client to generate certificates and how to automatically configure NGINX Open Source and NGINX Plus to use them.

How Let’s Encrypt Works

Before issuing a certificate, Let’s Encrypt validates ownership of your domain. The Let’s Encrypt client, running on your host, creates a temporary file (a token) with the required information in it. The Let’s Encrypt validation server then makes an HTTP request to retrieve the file and validates the token, which verifies that the DNS record for your domain resolves to the server running the Let’s Encrypt client.

Prerequisites

Before starting with Let’s Encrypt, you need to:

Now you can easily set up Let’s Encrypt with NGINX Open Source or NGINX Plus (for ease of reading, from now on we’ll refer simply to NGINX).

Note: We tested the procedure outlined in this blog post on Ubuntu 16.04 (Xenial).

Step 1 - Download the Let’s Encrypt Client

First, download the Let’s Encrypt client, certbot:

                            $ apt-get update

                            //Command for Ubuntu 18.x
                            $ sudo apt-get install certbot
                            $ apt-get install python-certbot-nginx

                            //Command for Ubuntu 20.x
                            $ sudo apt install certbot python3-certbot-nginx
                        

Step 2 - Set Up NGINX

certbot can automatically configure NGINX for SSL/TLS. It looks for and modifies the server block in your NGINX configuration that contains a server_name directive with the domain name you’re requesting a certificate for. In our example, the domain is www.example.com.

1. Assuming you’re starting with a fresh NGINX install, use a text editor to create a file in the /etc/nginx/conf.d directory named domain‑name.conf (so in our example, www.example.com.conf).

2. Specify your domain name (and variants, if any) with the server_name directive:

3. Save the file, then run this command to verify the syntax of your configuration and restart NGINX:

$ nginx -t && nginx -s reload

Step 3 - Obtain the SSL/TLS Certificate

The NGINX plug‑in for certbot takes care of reconfiguring NGINX and reloading its configuration whenever necessary.

1. Run the following command to generate certificates with the NGINX plug‑in:

                            $ sudo certbot --nginx -d example.com -d www.example.com

2. Respond to prompts from certbot to configure your HTTPS settings, which involves entering your email address and agreeing to the Let’s Encrypt terms of service.

When certificate generation completes, NGINX reloads with the new settings. certbot generates a message indicating that certificate generation was successful and specifying the location of the certificate on your server.

                            Congratulations! You have successfully enabled https://example.com and https://www.example.com

                            -------------------------------------------------------------------------------------
                            IMPORTANT NOTES:

                            Congratulations! Your certificate and chain have been saved at:
                            /etc/letsencrypt/live/example.com/fullchain.pem
                            Your key file has been saved at:
                            /etc/letsencrypt/live/example.com//privkey.pem
                            Your cert will expire on 2017-12-12.

Note: Let’s Encrypt certificates expire after 90 days (on 2017-12-12 in the example). For information about automatically renenwing certificates, see Automatic Renewal of Let’s Encrypt Certificates below.

If you look at domain‑name.conf, you see that certbot has modified it:

                            server {
                                listen 80 default_server;
                                listen [::]:80 default_server;
                                root /var/www/html;
                                server_name  example.com www.example.com;

                                listen 443 ssl; # managed by Certbot

                                # RSA certificate
                                ssl_certificate /etc/letsencrypt/live/example.com/fullchain.pem; # managed by Certbot
                                ssl_certificate_key /etc/letsencrypt/live/example.com/privkey.pem; # managed by Certbot

                                include /etc/letsencrypt/options-ssl-nginx.conf; # managed by Certbot

                                # Redirect non-https traffic to https
                                if ($scheme != "https") {
                                    return 301 https://$host$request_uri;
                                } # managed by Certbot
                            }

Step 4 - Automatically Renew Let’s Encrypt Certificates

Let’s Encrypt certificates expire after 90 days. We encourage you to renew your certificates automatically. Here we add a cron job to an existing crontab file to do this.

1. Open the crontab file. Use the nano editor if prompted. Generally its option 1

$ crontab -e 

2. Add the certbot command to run daily. In this example, we run the command every day at noon. The command checks to see if the certificate on the server will expire within the next 30 days, and renews it if so. The --quiet directive tells certbot not to generate output.

0 12 * * * /usr/bin/certbot renew --quiet

3. Save and close the file. All installed certificates will be automatically renewed and reloaded.

Summary

We’ve installed the Let’s Encrypt agent to generate SSL/TLS certificates for a registered domain name. We’ve configured NGINX to use the certificates and set up automatic certificate renewals. With Let’s Encrypt certificates for NGINX and NGINX Plus, you can have a simple, secure website up and running within minutes.

Installing PHP MYADMIN

sudo apt update // to update your packages
sudo apt install phpmyadmin // to install phpmyadmin
apache2 // (direct press enter)
sudo ln -s /usr/share/phpmyadmin /var/www/html // to create shortcut key for phpmyadmin at /var/www/html/
Now open phpmyadmin in the browser // You can login by username and password, which you set before.

Next step is to create a database and name it as you like. Then select the database and import the data .sql file using the file included in your folder.

1. Login to your FTP using Filezilla or other FTP you have.

2. Based on the kind of hosting, you may need to use SFTP or normal FTP Connection. If you use a cloud server + Filezilla, select SFTP & enter the same SSH credentials which you use to login in the terminal.

3. The website code is built on codeigniter which uses PHP as their base framework.

4. Now upload this folder in your ftp public folder. For Cloud hosting it is generally /var/www/html and for shared hosting or cpanel hosting it is public_html ( you can make folder with name like Admin and upload the content of the public-html and not the folder ).

5. Once uploading is finished below are the parameters to change,

1. Open Application -> Config -> config.php. This is the file where you need to change all settings.

2. Change the database credentials in database.php file located under application > config

3. Change below items

- System is integrated with stripe, please login to stripe.com and create yours account with your valid credentials and that will get you a publishable key and secret key. Please replace the above parameter.

- System is integrated with onesignal, https://onesignal.com for more details for pricing , up to 10,000 push messages you can send for free every month, which is humble enough for startup businesses. Please replace your ids in below code once you have configured the Appstore and Firebase Projects to generate your app keys and push certificates. The admin key is for the owner app and user key is for the customers app.

- For sending emails you need to change the below parameters. To begin with you can use Gmail account and it looks like this:

- You can use any SMTP server of your choice. Amazon also offers SES (Amazon Simple Email services) which is cheaper and can be used to send large amounts of emails.

Some important items before setting up

This guide covers how to run and debug Ionic apps on iOS simulators and devices using Capacitor. iOS apps can only be developed on macOS with Xcode installed.

There are two workflows for running Ionic apps on iOS:

The Xcode approach is generally more stable, but the Ionic CLI approach offers live-reload functionality.

Xcode Setup

Xcode is the IDE for creating native iOS apps. It includes the iOS SDK and Xcode command-line tools. Xcode can be downloaded for free with an Apple account or it can be installed through the App Store.

Once Xcode is installed, make sure the command-line tools are selected for use:

$ xcode-select --install

Setting up a Development Team

All iOS apps must be code signed, even for development. Luckily, Xcode makes this easy with automatic code signing. The only prerequisite is an Apple ID.

Open Xcode and navigate to Xcode » Preferences » Accounts. Add an Apple ID if none are listed. Once logged in, a Personal Team will appear in the team list of the Apple ID.

Creating an iOS Simulator

The iOS simulator emulates iOS devices on Macs. The following documentation is a quick way to get the iOS simulator set up. For more information, see Apple's documentation.

Open Xcode and navigate to Window » Devices and Simulators. Create an iPhone 11 simulator if one does not already exist.

Capacitor Setup

Additional setup is required for Capacitor to support programmatic builds. This app was built using Capacitor and may require additional support or skills for Capacitor. It is best to run it on Capacitor. However if you are building on Cordova, this section is not necessary.

Project Setup

Before apps can be deployed to iOS simulators and devices, the native project must be configured.

1. Capacitor Commands.

The folowing commands are used to deploy the app.

                        npx cap add android
                        npx cap add ios
                        npx cordova-res --skip-config --copy
                        cordova-res android --skip-config --copy
                        cordova-res ios --skip-config --copy
                        ionic cap build android
                        ionic cap build ios

2. Set the Package ID.

- For Capacitor, open the capacitor.config.ts file located in the root folder and modify the appId property.

3. Open the project in Xcode.

For Capacitor, run the following to open the app in Xcode:

$ ionic capacitor open ios

4. In Project navigator, select the project root to open the project editor. Under the Identity section, verify that the Package ID that was set matches the Bundle Identifier.
5. In the same project editor, under the Signing section, ensure Automatically manage signing is enabled. Then, select a Development Team. Given a Development Team, Xcode will attempt to automatically prepare provisioning and signing.

Running with Xcode

In this workflow, Xcode can automatically fix common compilation and signing issues that can occur.

1. Develop the Ionic app and sync it to the native project.
With each meaningful change, Ionic apps must be built into web assets before the change can appear on iOS simulators and devices. The web assets then must be copied into the native project. Luckily, this process is made easy with a single Ionic CLI command.
Run the following:

$ ionic cap sync

2. In Xcode, select a target simulator or device and click the play button.

Running with the Ionic CLI

The Ionic CLI can build, copy, and deploy Ionic apps to iOS simulators and devices with a single command. It can also spin up a development server, like the one used in ionic serve, to provide live-reload functionality.

With live-reload, changes made to the app's source files trigger a rebuild of web assets and the changes are reflected on the simulator or device without having to deploy again.

Warning: For iOS devices, the device and the computer need to be on the same Wi-Fi network. An external URL for the dev server is also required so the device can connect to it. Use --external (or --host=0.0.0.0) to bind to external addresses.

Live-reload with Capacitor

Capacitor does not yet have a way to build native projects. It relies on Xcode to build and deploy app binaries. However, the Ionic CLI can boot up a live-reload server and configure Capacitor to use it with a single command.

Run the following, then select a target simulator or device and click the play button in Xcode:

$ ionic cap run ios -l --external

Debugging iOS Apps

Once an app is running on an iOS device or simulator, it can be debugged in Safari.

Using Safari Web Inspector

Safari has Web Inspector support for iOS simulators and devices. Open the Develop menu and select the simulator or device, then select the Ionic App to open Web Inspector.

If the Develop menu is hidden, enable it in Safari » Preferences » Advanced » Show Develop menu in menu bar.

If the app isn't listed, the Web Inspector may need to be enabled on the device in Settings » Safari » Advanced » Web Inspector.

Viewing Native Logs

If running with Xcode, native logs can be found in in the Xcode Console.

If the Console is hidden, enable it in View » Debug Area » Activate Console.

This guide covers how to run and debug Ionic apps on Android emulators and devices using Capacitor or Cordova. Android apps can be developed on Windows, macOS, and Linux.

Android Studio

Android Studio> is the IDE for creating native Android apps. It includes the Android SDK, which will need to be configured for use in the command line.

Android Studio is also used to create Android virtual devices, which are required for the Android emulator. Ionic apps can also be launched to a device.

Installing Android Studio

Download Android Studio from the Android website. More detailed installation instructions can be found in the User Guide.

Installing the Android SDK

Once installed, open Android Studio. The IDE should detect that the Android SDK needs to be installed. In the SDK Components Setup screen, finish installing the SDK. Keep note of the Android SDK Location.

By default, the latest stable SDK Platform is installed, which includes a collection of packages required to target that version of Android.

To install system images and other minor SDK platform packages, you may need to ensure Show Package Details is checked at the bottom of the SDK Manager.

For future reference, the Android SDK can be managed with Android Studio in the Configure » SDK Manager menu of the Android Studio welcome screen or Tools » SDK Manager inside Android projects.

Configuring Command Line Tools

The Android SDK ships with useful command-line tools. Before they can be used, some environment variables must be set. The following instructions are for macOS and Linux. For Windows, check the documentation on setting and persisting environment variables in terminal sessions.

In ~/.bashrc, ~/.bash_profile, or similar shell startup scripts, make the following modifications:

1. Set the ANDROID_SDK_ROOT environment variable. This path should be the Android SDK Location used in the previous section.

$ export ANDROID_SDK_ROOT=$HOME/Library/Android/sdk

2. Add the Android SDK command-line directories to PATH. Each directory corresponds to the category of command-line tool.

For apksigner and zipalign, $ANDROID_SDK_ROOT/build-tools must also be added to PATH.

Creating an Android Virtual Device

Android Virtual Devices (AVDs) are blueprints that the Android emulator uses to run the Android OS. The following documentation is a quick way to get the Android emulator set up. For more detailed instructions and information, see the Android documentation.

AVDs are managed with the AVD Manager. In the Android Studio welcome screen, click Configure » AVD Manager. The AVD Manager can also be opened inside Android projects in the Tools » AVD Manager menu.

Click Create Virtual Device and select a suitable device definition. If unsure, choose Pixel 2. Then, select a suitable system image. If unsure, choose Pie (API 28) with Google Play services. See Android version history for information on Android versions.

Once the AVD is created, launch the AVD into the Android emulator. Keeping the emulator running is the best way to ensure detection while developing Ionic apps for Android.

Set up an Android Device

Actual Android hardware can also be used for Ionic app development. But first, the device must be set up for development. The following documentation is a quick way to set up Android devices for development. For more detailed instructions and information, see the Android documentation.

1. Enable USB debugging on the device. Open Settings, navigate to Developer options, and enable USB debugging. The Developer options menu may need to be enabled first. See the Android documentation for instructions.

2. Ensure the device has permission to connect to the computer. For macOS, no additional setup is required. For Windows, install the OEM USB drivers.

Verify the connection works by connecting the device to the computer with a USB cable and using the following command:

$ adb devices

The device should be listed. See the full adb documentation for troubleshooting and detailed information.

Cordova Setup

Additional setup is required for Cordova to support programmatic builds. This section is not necessary for Capacitor.

Java

Native Android apps are compiled with the Java programming language. Download JDK8 from the download page.

Gradle

Gradle is the build tool used in Android apps and must be installed separately. See the install page for details.

Project Setup

Before apps can be deployed to Android simulators and devices, the native project must be configured.

1. Generate the native project, if it does not already exist.

For Capacitor, run the following:

$ ionic capacitor add android

For Cordova, run the following:

$ ionic cordova prepare android

2. Set the Package ID.

- For Capacitor, open the capacitor.config.json file and modify the appId property.

- For Cordova, open the config.xml file and modify the id attribute of the root element, widget. See the Cordova documentation for more information.

                                        mobileprefix: '+44', //For whatsapp messages
                                        playstore: 'https://play.google.com/store/apps/details?id=io.flowerapp',
                                        appstore: 'https://itunes.apple.com/app/idxxxxxxxxxxx/idxxxxxxxxxxx',
                                        iosrateandreview: 'itms-apps://apps.apple.com/gb/app/flowerapp/idxxxxxxxxxxx?mt=8&action=write-review',
                                        app_share_text: 'Awesome Food. Order Now using the app:',
                                        androidappid: 'io.flowerapp',
                                        iosappid: 'xxxxxxxxxxx'
                                        

c. Now let's run the command to install all dependencies. You will need to have the current working forlder active on your terminal to be able to run the command successfully. This is generally done by dragging the folder directly on the Termincal icon.

3. npm install

5. Running App in Mobile
- The Xcode approach is generally more stable, but the Ionic CLI approach offers live-reload functionality.
