Open the terminal by pressing the Ctrl+Alt+T keys on your keyboard or by searching for “terminal” in the applications menu.

Install the PHP MySQL extension by running the following command:

$ sudo apt install php8.1-mysql

This extension allows PHP to communicate with MySQL.

Restart the Apache web server by running the following command:

$ sudo systemctl restart apache2

This command is necessary for Apache to recognize the newly installed PHP MySQL extension.

To test if PHP is configured to work with MySQL, create a new PHP file by running the following command in your terminal:

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

This command will open a new file in the Nano text editor. Add the following code to the file:

<?php
// Test PHP MySQL connection
$servername = "localhost";
$username = "root";
$password = "your_password_here";

// Create connection
$conn = new mysqli($servername, $username, $password);

// Check connection
if ($conn->connect_error) {
    die("Connection failed: " . $conn->connect_error);
}
echo "Connected successfully";
?>

Replace “your_password_here” with the password you set for the MySQL root user during installation.

Save the file by pressing Ctrl+X, then Y, and then Enter.

To test the PHP MySQL connection, open a web browser and navigate to “http://localhost/test.php“. You should see the message “Connected successfully” displayed in your browser.

Congratulations! You have successfully configured PHP and MySQL to work with Apache on your Linux Mint system. You can now start building and testing web applications on your local development environment.

Step 5: Install and Setup phpMyAdmin

phpMyAdmin is a free and open-source tool that provides a web-based interface for managing MySQL databases. It allows you to easily create, modify, and delete databases and tables, as well as manage users and permissions. In this step, we will show you how to install and set up phpMyAdmin on your Linux Mint system.

Open the terminal by pressing the Ctrl+Alt+T keys on your keyboard or by searching for “terminal” in the applications menu.

Install phpMyAdmin by running the following command:

$ sudo apt-get install phpmyadmin

Next, you will be prompted to configure the database for phpMyAdmin, select “Yes” to use dbconfig-common.

Enter the password that you set for the MySQL root user during the MySQL installation process.

You will now be prompted to create a password for phpMyAdmin. Choose a strong password and press Enter.

Confirm the password by re-entering it and pressing Enter.

phpMyAdmin is now installed and configured on your Linux Mint system.

Restart Apache for the changes to take effect by running the following command:

$ sudo systemctl restart apache2

Open your web browser and go to http://localhost/phpmyadmin. You should see the phpMyAdmin login page.

$ sudo ln -s /usr/share/phpmyadmin /var/www/html/phpmyadmin

Enter the username as “root” and the password that you set during the phpMyAdmin installation process.

Congratulations! You have successfully installed and set up phpMyAdmin on your Linux Mint system. You can now use phpMyAdmin to manage your MySQL databases through a web-based interface.

Step 6: Test your installation

After installing Apache, PHP 8, and MySQL on your Linux Mint system and configuring them to work together, it is important to test your installation to ensure that everything is working properly. In this step, we will create a simple PHP script to test our installation.

Open the terminal by pressing the Ctrl+Alt+T keys on your keyboard or by searching for “terminal” in the applications menu.

Navigate to the Apache document root directory by running the following command:

$ cd /var/www/html

Create a new PHP file called “test.php” by running the following command:

$ sudo nano test.php

Add the following code to the “test.php” file:

<?php
// Test PHP and MySQL installation
phpinfo();
?>

This code will display the PHP information page, which will show you information about your PHP installation and configuration.

Save the file by pressing Ctrl+X, then Y, and then Enter.

To test your installation, open a web browser and navigate to “http://localhost/test.php“. You should see a page that displays information about your PHP installation and configuration.

Congratulations! You have successfully installed Apache, PHP 8, and MySQL on your Linux Mint system and tested your installation. You are now ready to start building and testing web applications on your local development environment.

Step 7: Granting User Permissions to Apache Web Directory

By default, the Apache web server is installed with its web directory owned by the root user, which means that a regular user account cannot write or modify files within the directory. In order to allow a regular user to modify files within the Apache web directory, we need to grant the appropriate permissions. In this step, we will add the current user to the Apache web directory with the correct permissions.

Open the terminal by pressing the Ctrl+Alt+T keys on your keyboard or by searching for “terminal” in the applications menu.

Check the ownership of the Apache web directory by running the following command:

$ ls -l /var/www/html

This command will show you the owner and group of the Apache web directory. By default, it is owned by the root user.

Add the current user to the Apache group by running the following command:

$ sudo usermod -a -G www-data $USER

This command adds the current user to the Apache group, which is necessary for the user to have write access to the web directory.

Change the ownership of the Apache web directory to the Apache group by running the following command:

$ sudo chown -R www-data:www-data /var/www/html

This command changes the ownership of the web directory to the Apache group, which allows the group to have write access to the directory.

Change the permissions of the Apache web directory to allow the Apache group to write to the directory by running the following command:

$ sudo chmod -R 775 /var/www/html

This command sets the permission of the web directory to 775, which allows the owner and group to read, write, and execute files within the directory.

To verify that the permissions have been set correctly, create a new file in the Apache web directory by running the following command:

$ nano /var/www/html/test.txt

Add some text to the file and save it by pressing Ctrl+X, then Y, and then Enter.

Check that the file was created with the correct permissions by running the following command:

$ ls -l /var/www/html/test.txt

The output of this command should show that the file is owned by the Apache group and that the group has write permissions.

Congratulations! You have successfully added the current user to the Apache web directory with the correct permissions. You can now modify and create files within the web directory without needing root privileges.
