How To Install Linux, Apache, MySQL, PHP (LAMP) Stack on Debian 9 Stretch

Here are the steps to install the LAMP stack on Debian 9 Stretch:

1. Install Apache Web Server:
   sudo apt-get update
sudo apt-get install apache2

2. Install MySQL Server:
   sudo apt-get install mysql-server


   During the installation, you’ll be prompted to set a root password for MySQL.

3. Install PHP:
   sudo apt-get install php libapache2-mod-php php-mysql

4. Configure Apache to use PHP:
   sudo nano /etc/apache2/mods-enabled/dir.conf


   Change the order of the files so that index.php is listed first:

   <IfModule mod_dir.c>
DirectoryIndex index.php index.html index.cgi index.pl index.xhtml index.htm
</IfModule>

5. Restart Apache:
   sudo systemctl restart apache2

6. Verify the LAMP installation by creating a test PHP file:
   sudo nano /var/www/html/info.php


   Add the following code to the file:

   <?php
phpinfo();
?>

7. Access the test PHP file in your web browser:
   http://your_server_ip_or_domain/info.php


The LAMP stack should now be installed and working on your Debian 9 system.
