How to Install Joomla 3 on Debian 9

We’ll show you, How to Install Joomla 3 on Debian 9. Joomla is on of the most popular free and open-source CMS (Content Management System) that allows you to easily create and manage dynamic websites. It is written in PHP, and it can store its data in either MySQL or PostgreSQL database. In this tutorial, we will show you how to install Joomla 3 on Debian 9 using LAMP (Linux, Apache, MariaDB, PHP). Installing Joomla 3 on Debian 9, is easy and should take less then 10 minutes.

1. Getting Started

First, you need to login to your server via SSH as user root:


and replace “IP_ADDRESS” and “PORT_NUMBER” with your actual server IP address and SSH port number.

Before we begin with the installation, let’s make sure that your Debian 9 server is up-to-date by running the following commands:

apt-get update
apt-get upgrade

2. Install Apache

To install the Apache web server, run the following command:

apt-get install apache2

After the installation is completed, you can enable the service to start automatically upon system boot with:

systemctl enable apache2

To verify that the Apache server is running, you can run the following command:

systemctl status apache2

2. Install PHP 7.0

Next, we will install PHP 7 with some additional PHP modules:

apt-get install php7.0 libapache2-mod-php7.0 php7.0-mysql php7.0-cli php7.0-common php7.0-json php7.0-opcache php7.0-readline php7.0-gd php7.0-mcrypt php7.0-intl php7.0-curl php7.0-zip

3. Install MariaDB

The next step is to install the MariaDB database server. To do this, run the following command:

apt-get install mariadb-server

After the installation is completed, you can start the database server and enable it to automatically start upon boot, with:

systemctl start mariadb
systemctl enable mariadb

You can also run the “mysql_secure_installation” script provided by MariaDB in order to secure your installation:


After you have answered all the questions you can now go ahead and login to MariaDB as root using your root password, with the following command:

mysql -u root -p

To create a new database for our Joomla installation, run the following commands:

GRANT ALL PRIVILEGES ON joomla_db.* TO 'joomla_user'@'localhost' IDENTIFIED BY 'PASSWORD';

Make sure to replace “PASSWORD” with an actual, strong password.

4. Install Joomla 3 on Debian 9

Now that your LAMP server is ready, we can finally install Joomla.

You can download the latest stable version with the following command:


Create a new joomla directory inside the Apache document root directory on your server and unpack the archive:

mkdir /var/www/html/joomla
unzip -d /var/www/html/joomla

Change the ownership of the joomla directory:

5. Set up Apache Virtual Host

If you want to access your Joomla installation using your own domain name, you will also need to create an Apache virtual host file:

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

And enter the following content inside this file:

<VirtualHost *:80>
DocumentRoot /var/www/html/joomla

<Directory /var/www/html/joomla>
Options FollowSymLinks
AllowOverride All
Order allow,deny
allow from all

ErrorLog /var/log/apache2/joomla-error_log
CustomLog /var/log/apache2/joomla-access_log common

6. Enable the Virtual Host File

and do not forget to replace “” with your own domain name. Finally, you need to enable the virtual host file with:

ln -s /etc/apache2/sites-available/joomla.conf /etc/apache2/sites-enabled/joomla.conf

7. Restart Apache

Restart your Apache with:

systemctl restart apache2
