LAMP Stack Explained: Linux, Apache, MySQL, and PHP

LAMP represents a common open-source software stack, including Linux, Apache, MySQL (or MariaDB), and PHP (or Perl/Python). It's frequently used to run dynamic websites and web apps on Linux servers.

Components of LAMP:

• Linux: The underlying operating system.

  • Apache: A widely used web server that processes HTTP requests and delivers web content.
  • MySQL/MariaDB: A relational database management system (RDBMS) for storing and managing data.
  • PHP/Python/Perl: A programming language for server-side scripting.

How LAMP Works:

Linux forms the stable base for all components. Apache receives incoming HTTP requests and serves web pages. PHP (or another scripting language) processes dynamic content. MySQL/MariaDB stores and manages website data.

Installing LAMP on Linux:

On Ubuntu/Debian:

1. sudo apt install apache2 mysql-server php php-mysql
2. Enable and start services:
3. sudo systemctl enable apache2
   • sudo systemctl start apache2
   • sudo systemctl enable mysql
4. sudo systemctl start mysql

On CentOS/Fedora:

1. sudo apt install httpd mysql-server php php-mysql
   1. Enable and start services:
   2. sudo systemctl enable httpd
2. sudo systemctl start httpd
3. sudo systemctl enable mysql
   • sudo systemctl start mysql

Verify Installation:

• Apache: Open a web browser and go to http://your-server-ip. You should see the Apache default page.
• PHP: Create a test file /var/www/html/info.php with the following content: Then access http://your-server-ip/info.php in your browser.
