This comprehensive Linux guide expects that you run the following commands as root user but if you decide to run the commands as a different user then ensure that the user has sudo access and that you precede each of the privileged commands with sudo

LAMP is an archetypal model of web service stacks, named as an acronym of the names of its original four open-source components: the Linux operating system, the Apache HTTP Server, the MariaDB database Server, and the PHP programming language.

This tutorial will guide how to install LAMP stack (Linux, Apache Server, MariaDB database and PHP) on Debian buster 10. You can follow the steps below.

Steps To Install LAMP Stack

To install the LAMP stack, you first need to have Debian 10 Buster running on your system with a non-root sudo-enabled user account and a basic firewall.

Updating Debian 10 Buster

The first step to install the LAMP stack on your system is to update your Debian 10 Buster and it’s repositories to the latest version. You can run the following command

root@codesposts:~$ apt update && apt -y upgrade

Installing Apache Server

You can run the following commands to install the Apache web server on your Debian 10.

root@codesposts:~$ apt install apache2
root@codesposts:~$ apt install apache2-utils

Verifying The Services

After installing Apache web server, you can verify it’s process by running the command below:

root@codesposts:~$ systemctl status apache2

● apache2.service - The Apache HTTP Server
   Loaded: loaded (/lib/systemd/system/apache2.service; enabled; vendor preset:
   Active: active (running) since Tue 2019-08-06 11:58:27 UTC; 33s ago

           ├─14780 /usr/sbin/apache2 -k start

           └─14783 /usr/sbin/apache2 -k start

Aug 06 11:58:27 codesposts systemd[1]: Started The Apache HTTP Server.
lines 1-12/12 (END)

Verifying The Version

You can verify the version of Apache web server by running the following command:

root@codesposts:~$ apache2 -v
Server version: Apache/2.4.25 (Debian)
Server built:   2019-04-02T19:05:13

Enabling Startup With Boot

If you want to enable the Apache services to start with the boot, you can run the following command

root@codesposts:~$ systemctl enable apache2

Displaying Apache Full Status

If you want to display the full status of the Apache services, you can install the elinks on your system.

root@codesposts:~$ apt install elinks

After the installation, run the following command to display the full status

root@codesposts:~$ apache2ctl fullstatus

Setting Up And Opening Port

If you are using UFW firewall, run the following command to open the TCP port 80 on your system

root@codespsots:~$ ufw allow http

Now we need to set www-data (Apache user) as the owner of document root (otherwise known as web root). By default it’s owned by the root user.

root@codesposts:~$ chown www-data:www-data /var/www/html/ -R

Installing MariaDB Database Server

Run the following commands to install the MariaDB Database Server ( drop-in replacement for MySQL-Server)

root@codesposts:~$ apt install -y mariadb-server
root@codesposts:~$ apt install -y mariadb-client

Verifying Installed Version

To verify the installed version, run the following command

root@codesposts:~$ apt policy mariadb-server

  Installed: 10.1.38-0+deb9u1
  Candidate: 10.1.38-0+deb9u1
  Version table:
 *** 10.1.38-0+deb9u1 500
        500 stretch/main amd64 Packages
        100 /var/lib/dpkg/status
     10.1.37-0+deb9u1 500
        500 stretch/updates/main amd64 Packages

Verifying Services

To check the status of the services of the MariaDB, run the following command

root@codesposts:~$ systemctl status mariadb

● mariadb.service - MariaDB 10.1.38 database server
   Loaded: loaded (/lib/systemd/system/mariadb.service; enabled; vendor preset: enabled)

Securing Database Server

Run the command below to secure your database server

root@codesposts:~$ mysql_secure_installation

 In order to log into MariaDB to secure it, we'll need the current
 password for the root user.  If you've just installed MariaDB, and
 you haven't set the root password yet, the password will be blank,
 so you should just press enter here.
 Enter current password for root (enter for none): 
 OK, successfully used password, moving on…
 Setting the root password ensures that nobody can log into the MariaDB
 root user without the proper authorisation.
 Set root password? [Y/n] Y
 New password: 
 Re-enter new password: 
 Password updated successfully!
 Reloading privilege tables..
  … Success!
 By default, a MariaDB installation has an anonymous user, allowing anyone
 to log into MariaDB without having to have a user account created for
 them.  This is intended only for testing, and to make the installation
 go a bit smoother.  You should remove them before moving into a
 production environment.
 Remove anonymous users? [Y/n] Y
  … Success!
 Normally, root should only be allowed to connect from 'localhost'.  This
 ensures that someone cannot guess at the root password from the network.
 Disallow root login remotely? [Y/n] Y
  … Success!
 By default, MariaDB comes with a database named 'test' that anyone can
 access.  This is also intended only for testing, and should be removed
 before moving into a production environment.
 Remove test database and access to it? [Y/n] Y
 Dropping test database…
 … Success!
 Removing privileges on test database…
 … Success! 
 Reloading the privilege tables will ensure that all changes made so far
 will take effect immediately.
 Reload privilege tables now? [Y/n] Y
  … Success!
 Cleaning up…
 All done!  If you've completed all of the above steps, your MariaDB
 installation should now be secure.
 Thanks for using MariaDB!

Testing MariaDB Installation

To test the installation of the MariaDB Database Server, run the following command

root@codesposts:~$ mysql -u root -p

Enter password:
Welcome to the MariaDB monitor.  Commands end with ; or \g.
Your MariaDB connection id is 6
Server version: 10.1.38-MariaDB-0+deb9u1 Debian 9.8

Copyright (c) 2000, 2018, Oracle, MariaDB Corporation Ab and others.

Type 'help;' or '\h' for help. Type '\c' to clear the current input statement.

Enabling Startup With Boot

If you want to enable the MariaDB services to start with the boot, you can run the following command

root@codesposts:~$ systemctl enable mariadb

Installing PHP

To install the latest version of PHP on your system, you can follow the steps given below

root@codesposts:~$ apt install php libapache2-mod-php php-cli php-fpm php-json php-pdo php-mysql php-zip php-gd  php-mbstring php-curl php-xml php-pear php-bcmath

Enabling Apache PHP Module

To enable the Apache module, run the following command then restart the serrvice

root@codesposts:~$ a2enmod php7.3 

root@codespsots:~$ systemctl restart apache2

Verifying The Version

To verify the version of the PHP installed, you can run the following command

root@codesposts:~$ php -v

PHP 7.3.4-2 (cli) (built: Apr 13 2019 19:05:48) ( NTS )
Copyright (c) 1997-2018 The PHP Group
Zend Engine v3.3.4, Copyright (c) 1998-2018 Zend Technologies
    with Zend OPcache v7.3.4-2, Copyright (c) 1999-2018, by Zend Technologies

Testing PHP Scripts

To test the php scripts with Apache server, we need to create a codesposts.php file in the Web root directory with a command line text editor.

root@codesposts:~$ nano /var/www/html/codesposts.php

Copy and paste the following code in the file

<?php phpinfo(); ?>

To save a file in Nano text editor, press Ctrl+O, then press Enter to confirm. To exit, press Ctrl+X.

Now open your browser and enter server-ip-address/codesposts.php. Replace sever-ip-address with your actual IP. If you follow this tutorial on your local computer, then type
