Installing LAMP Stack (Linux, Apache, MySQL, PHP) on Ubuntu 20.04

The LAMP stack is a popular open-source web development platform that includes Linux as the operating system, Apache as the web server, MySQL as the database management system, and PHP as the scripting language.

Step 1: Install Apache

Begin by updating the package list:

$ sudo apt update

Then install the Apache web server:

$ sudo apt install apache2

Start and enable Apache to run on system boot:

$ sudo systemctl start apache2
$ sudo systemctl enable apache2

Step 2: Install MySQL

Install the MySQL server package:

$ sudo apt install mysql-server

During the installation, you will be prompted to set a root password. Follow the on-screen instructions to complete the installation.

Step 3: Install PHP

Install PHP and its required extensions:

$ sudo apt install php libapache2-mod-php php-mysql

After the installation, restart Apache for the changes to take effect:

$ sudo systemctl restart apache2

Step 4: Test LAMP Stack

Create a PHP file to test if the LAMP stack is installed and working correctly:

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

Add the following code to the file:

Save and close the file.

Open a web browser and type your server's IP address or domain name followed by "/info.php" (e.g., http://your_server_ip/info.php). If everything is set up correctly, you should see the PHP information page.

Conclusion

Congratulations! You've successfully installed the LAMP stack on Ubuntu 20.04. You now have a web development platform with Linux, Apache, MySQL, and PHP ready to use for building and running dynamic websites and applications.
