Install Joomla on Ubuntu 22.04

Step 1: Install Apache

sudo apt update

sudo apt install apache2

Check that it starts at boot and that it runs:

sudo systemctl is-enabled apache2

sudo systemctl status apache2

Open the firewall. Allow SSH first so that you do not lock yourself out:

sudo ufw allow OpenSSH
sudo ufw allow "Apache Full"

sudo ufw enable

sudo ufw reload

sudo ufw status

Step 2: Install MariaDB

sudo apt install mariadb-server

sudo systemctl is-enabled mariadb

sudo systemctl status mariadb

Secure the install:

sudo mysql_secure_installation

Step 3: Install PHP

sudo apt install php libapache2-mod-php php-mysql php-xml php-mbstring php-curl php-zip php-gd php-intl

Restart Apache and test PHP:

sudo systemctl restart apache2
sudo nano /var/www/html/phpinfo.php

Add:

<?php
phpinfo();
?>

Open http://your_server_ip/phpinfo.php.

Delete this file after the test: sudo rm /var/www/html/phpinfo.php.

Step 4: Create the database

sudo mysql -u root -p

CREATE DATABASE joomla;
CREATE USER 'joomlauser'@'localhost' IDENTIFIED BY 'StrongPassword';
GRANT ALL PRIVILEGES ON joomla.* TO 'joomlauser'@'localhost';
FLUSH PRIVILEGES;
EXIT;

Step 5: Download Joomla

Get the link of the current full package from the Joomla website, and download it:

cd /tmp
wget https://downloads.joomla.org/cms/joomla5/5-1-2/Joomla_5-1-2-Stable-Full_Package.zip

Unzip it into the web folder:

sudo mkdir -p /var/www/html/joomla
sudo unzip Joomla_5-1-2-Stable-Full_Package.zip -d /var/www/html/joomla

Set the owner:

sudo chown -R www-data:www-data /var/www/html/joomla
sudo chmod -R 755 /var/www/html/joomla

Step 6: Finish in the browser

Open http://your_server_ip/joomla. The Joomla installer starts.

1. Enter the site name and the admin user details.
2. Enter the database details: type MySQLi, host localhost, the user and password from step 4, and the database name joomla.
3. Click Install.
4. When it ends, remove the installation folder if the installer asks for it.

Add an SSL certificate (for example with certbot --apache) before you use the site for real.

Quick recap

• Install Apache, MariaDB and PHP.
• Create a database and user.
• Unzip Joomla into /var/www/html/joomla and run the web installer.
