This guide will discuss how you as a user can install and setup Apache, MariaDB and PHP ( LAMP Stack) on Ubuntu 20.04 (Focal Fossa) Linux system. LAMP is an acronym for – Linux, Apache, MySQL/MariaDB and PHP. LAMP Stack is not a single package but a set of open-source tools that are used to power web applications and websites. Each component can be used independently to serve an application.

Install LAMP Stack on Ubuntu 20.04 (Focal Fossa)

LAMP Stack comprises of the following open source software applications.

  • Linux – This is the operating system hosting the Applications.
  • Apache – Apache HTTP is a free and open-source cross-platform web server.
  • MySQL/MariaDB – Open Source relational database management system.
  • PHP – Programming/Scripting Language used for developing Web applications.

You can use a Virtual Machine on Premise, in the cloud or a dedicated server to install and configure LAMP Stack on Ubuntu 20.04 (Focal Fossa) operating system. A use account used in this setup needs sudo privileges to install software, edit configuration files, and manage services.

Step 1: Update Ubuntu 20.04 (Focal Fossa)

Before we can start installation of LAMP Stack packages on Ubuntu 20.04, it is recommended to keep the repository and packages up to date.

sudo apt update && sudo apt -y upgrade

Step 2: Install MariaDB Database Server

MariaDB is a relational database management system forked from MySQL. It is free and Open source. Install it using the guide below.

How To Install MariaDB Server on Ubuntu 20.04 (Focal Fossa)

After the installation, ensure you secure the database server. This includes:

  • Setting strong root password
  • Removing anonymous users
  • Disabling remote login for root user.
  • Removing test database and access to it

Run the command below to secure your database server.

$ sudo mysql_secure_installation
NOTE: RUNNING ALL PARTS OF THIS SCRIPT IS RECOMMENDED FOR ALL MariaDB
SERVERS IN PRODUCTION USE! PLEASE READ EACH STEP CAREFULLY!
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!

Test MariaDB database installation.

$ mysql -u root -p
 Enter password: 
 Welcome to the MariaDB monitor.  Commands end with ; or \g.

Step 3: Install Apache Web Server

Apache Web server packages are available on Ubuntu 20.04 official repositories. All that’s needed is execution of install command with sudo.

sudo apt install -y apache2 apache2-utils

Confirm Apache build and version.

$ sudo apache2 -v
Server version: Apache/2.4.41 (Ubuntu)
Server built:   2019-08-14T14:36:32

Service is started automatically after installation.

$ systemctl status apache2
 ● apache2.service - The Apache HTTP Server
      Loaded: loaded (/lib/systemd/system/apache2.service; enabled; vendor preset: enabled)
      Active: active (running) since Tue 2019-12-24 11:17:28 UTC; 20s ago
        Docs: https://httpd.apache.org/docs/2.4/
    Main PID: 721 (apache2)
       Tasks: 55 (limit: 614)
      Memory: 4.9M
      CGroup: /system.slice/apache2.service
              ├─721 /usr/sbin/apache2 -k start
              ├─723 /usr/sbin/apache2 -k start
              └─724 /usr/sbin/apache2 -k start
 Dec 24 11:17:28 ubuntu20 systemd[1]: Starting The Apache HTTP Server…
 Dec 24 11:17:28 ubuntu20 apachectl[720]: AH00558: apache2: Could not reliably determine the server's fully qualified domain name, using 10.10.1.122. Se>
 Dec 24 11:17:28 ubuntu20 systemd[1]: Started The Apache HTTP Server.

You can restart service or reload when a change is made by using systemctl command.

sudo systemctl reload apache2
sudo systemctl enable apache2

To enable the service to start at boot, use

sudo systemctl is-enabled apache2

To view Apache server full status, use apache2ctl command.

$ sudo apache2ctl fullstatus 

Your output should be similar to below.

Open server IP address on your browser to see default Apache page.

Step 4: Install PHP on Ubuntu 20.04

Now that we have both Apache and MariaDB installed, the missing piece is PHP. We will install PHP and standard extensions which are commonly used. The version of PHP installed on Ubuntu 20.04 is PHP 7.3.

sudo 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

Enable Apache module if not already enabled then restart the Web Server.

sudo a2enmod php7.3 

Confirm your PHP version.

$ php -v
PHP 7.3.11-0ubuntu1 (cli) (built: Nov 20 2019 14:21:42) ( NTS )
Copyright (c) 1997-2018 The PHP Group
Zend Engine v3.3.11, Copyright (c) 1998-2018 Zend Technologies
     with Zend OPcache v7.3.11-0ubuntu1, Copyright (c) 1999-2018, by Zend Technologies

Create a php script to test your LAMP stack installation.

echo "<?php phpinfo(); ?>" | sudo tee /var/www/html/phpinfo.php

Open your server IP and URL: http://[ServerIP/hostname]/phpinfo.php
