Joomla is a free and open-source content management system used to create, modify and manage the content of a website. It is simple and easy to use so you don’t need to have any HTML or CSS knowledge to build the website. It is written in PHP and uses MySQL as a database. It offers a wide range of features that make it a flexible content management system right out of the box. It comes with hundreds of free extensions that allow you to customize and extend the functionality.

In this tutorial, I will show you how to install Joomla CMS with Apache and Let’s Encrypt on Debian 10.

Prerequisites

  • A server running Debian 10.
  • A valid domain name pointed with your server IP.
  • A root password is configured the server.

Getting Started

First, update the system packages to the updated version by running the following command:

apt-get update -y

Once all the packages are updated, you can proceed to the next step.

Install LAMP Server

Next, you will need to install the Apache web server, MariaDB database, PHP and other PHP extensions to your system. You can install all of them with the following command:

apt-get install apache2 mariadb-server php openssl php-imagick php-common php-curl php-gd php-imap php-intl php-json php-ldap php-mbstring php-mysql php-pgsql php-smbclient php-ssh2 php-sqlite3 php-xml php-zip -y

Once all the packages are installed, you can proceed to the next step.

Create a Database for Joomla

Joomla uses MySQL or MariaDB to store its content. So you will need to create a database and user for Joomla.

First, connect to the MariaDB with the following command:

mysql

Once connected, create a database and user with the following command:

MariaDB [(none)]> CREATE DATABASE joomladb;

MariaDB [(none)]> GRANT ALL ON joomladb.* TO 'joomlauser'@'localhost' IDENTIFIED BY 'password';

Next, flush the privileges and exit from the MariaDB with the following command:

MariaDB [(none)]> FLUSH PRIVILEGES;

MariaDB [(none)]> EXIT;

Once you are finished, you can proceed to the next step.

Install Joomla

Next, download the latest version of Joomla with the following command:

wget https://downloads.joomla.org/cms/joomla3/3-9-25/Joomla_3-9-25-Stable-Full_Package.tar.bz2

Once the download is completed, create a directory for Joomla inside the Apache web root:

mkdir /var/www/html/joomla

Next, run the following command to extract the downloaded file to the Joomla directory:

bunzip2 Joomla_3-9-25-Stable-Full_Package.tar.bz2

tar -xvf Joomla_3-9-25-Stable-Full_Package.tar -C /var/www/html/joomla/

Next, set proper permission and ownership to the Joomla directory with the following command:

chown -R www-data:www-data /var/www/html/joomla

chmod -R 755 /var/www/html/joomla

Once you are finished, you can proceed to the next step.

Configure Apache Web Server

Next, you will need to create an Apache virtual host configuration file to host the Joomla.

You can create it with the following command:

nano /etc/apache2/sites-available/joomla.conf

Add the following lines:

   ServerName joomla.example.com 
   ServerAdmin [email protected]
   DocumentRoot /var/www/html/joomla
   
	    Allowoverride all
   

Save and close the file then enable the Apache virtual host with the following command:

a2ensite joomla

Next, restart the Apache service to apply the changes:

systemctl restart apache2

Next, verify the status of the Apache with the following command:

systemctl status apache2

You should get the following output:

Secure Joomla with Let’s Encrypt SSL

It is always a good idea to secure your website with Let’s Encrypt SSL. You will need to install the Certbot client to install and manage the SSL. You can install it with the following command:

apt-get install python3-certbot-apache -y

Once the Certbot is installed, run the following command to secure your website with Let’s Encrypt SSL:

certbot --apache -d joomla.example.com
