It is built on PHP and stores its data on an SQL-based database engine on the backend such as MySQL/MariaDB.

In this tutorial, we will show you how to install Joomla 4 on your Ubuntu 22.04 OS.

Step 1: Update Operating System

Update your Ubuntu 22.04 operating system to make sure all existing packages are up to date:

$ sudo apt update && sudo apt upgrade -y

Step 2: Install Apache webserver

You can install Apache via apt package manager by executing the following command.

$ sudo apt install apache2

You can start the Apache service and configure it to run on startup by entering the following commands:

$ sudo systemctl start apache2
$ sudo systemctl enable apache2

Verify the status of the Apache service using systemctl status command:

$ sudo systemctl status apache2

Output:

● apache2.service - The Apache HTTP Server
Loaded: loaded (/lib/systemd/system/apache2.service; enabled; vendor preset: enabled)
Active: active (running) since Tue 2022-04-26 15:18:33 UTC; 1min 31s ago
Docs: https://httpd.apache.org/docs/2.4/
Main PID: 13521 (apache2)
Tasks: 55 (limit: 2200)
Memory: 4.8M
CPU: 148ms
CGroup: /system.slice/apache2.service
├─13521 /usr/sbin/apache2 -k start
├─13523 /usr/sbin/apache2 -k start
└─13524 /usr/sbin/apache2 -k start

You can test to make sure everything is working correctly by navigating to:

http://your-IP-address

If everything is configured properly, you should be greeted by the default Apache2 Page, as seen below.

Step 3: Install PHP and PHP extensions for Joomla 4

You can install PHP 8.1 and other supporting packages using the following command:

$ sudo apt install php libapache2-mod-php php-dev php-bcmath php-intl php-soap php-zip php-curl php-mbstring php-mysql php-gd php-xml

Verify if PHP is installed.

php -v

Output:
PHP 8.1.2 (cli) (built: Apr 7 2022 17:46:26) (NTS)
Copyright (c) The PHP Group
Zend Engine v4.1.2, Copyright (c) Zend Technologies
with Zend OPcache v8.1.2, Copyright (c), by Zend Technologies

Step 4: Install MariaDB and create a database

You can install MariaDB with the following command:

$ sudo apt install mariadb-server

Start the database server daemon, and also enable it to start automatically at the next boot with the following commands:

$ systemctl start mariadb
$ systemctl enable mariadb

Verify the status of the MariaDB service using systemctl status command:

$ sudo systemctl status mariadb

Output:

● mariadb.service - MariaDB 10.6.7 database server
Loaded: loaded (/lib/systemd/system/mariadb.service; enabled; vendor preset: enabled)
Active: active (running)
Docs: man:mariadbd(8)
https://mariadb.com/kb/en/library/systemd/
Process: 27074 ExecStartPre=/usr/bin/install -m 755 -o mysql -g root -d /var/run/mysqld (code=exited, status=0/SUCCESS)
Process: 27075 ExecStartPre=/bin/sh -c systemctl unset-environment _WSREP_START_POSITION (code=exited, status=0/SUCCESS)
Process: 27077 ExecStartPre=/bin/sh -c [ ! -e /usr/bin/galera_recovery ] && VAR= || VAR=`cd /usr/bin/..; /usr/bin/galera_recovery`; [ $? -eq 0 ] && >
Process: 27117 ExecStartPost=/bin/sh -c systemctl unset-environment _WSREP_START_POSITION (code=exited, status=0/SUCCESS)
Process: 27119 ExecStartPost=/etc/mysql/debian-start (code=exited, status=0/SUCCESS)
Main PID: 27106 (mariadbd)
Status: "Taking your SQL requests now..."
Tasks: 7 (limit: 2200)
Memory: 57.0M
CPU: 880ms
CGroup: /system.slice/mariadb.service
└─27106 /usr/sbin/mariadbd

Once the database server is installed, log into the MariaDB prompt:

$ sudo  mysql -u root

To create a database, database user, and grant all privileges to the database user run the following commands:

MariaDB [(none)]> CREATE DATABASE joomla_db;
MariaDB [(none)]> CREATE USER 'joomla_user'@'localhost' IDENTIFIED BY 'Password';
MariaDB [(none)]> GRANT ALL ON joomla_db.* TO 'joomla_user'@'localhost';
MariaDB [(none)]> FLUSH PRIVILEGES;
MariaDB [(none)]> EXIT

Step 5: Download Joomla 4

We will now download the latest version of Joomla from the Official site.

Use the following command to download Joomla 4:

$ sudo wget https://downloads.joomla.org/cms/joomla4/4-1-2/Joomla_4-1-2-Stable-Full_Package.zip

Extract file into the folder /var/www/html/joomla/ with the following command,

$ sudo apt -y install unzip 
$ sudo unzip Joomla_4-1-2-Stable-Full_Package.zip -d /var/www/html/joomla

Enable permission for the Apache webserver user to access the files,

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

Step 6: Configure Apache Web Server for Joomla 4

Navigate to /etc/apache2/sites-available directory and run the following command to create a configuration file for your installation:

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

Add the following content:

<VirtualHost *:80>

ServerAdmin webmaster@your-domain.com

ServerName your-domain.com
ServerAlias www.your-domain.com
DocumentRoot /var/www/html/joomla

<Directory /var/www/html/joomla/>
        Options FollowSymlinks
        AllowOverride All
        Require all granted
</Directory>

ErrorLog ${APACHE_LOG_DIR}/your-domain.com_error.log
CustomLog ${APACHE_LOG_DIR}/your-domain.com_access.log combined

</VirtualHost>

Save the file and Exit.

Enable the Joomla virtual host:

$ sudo a2ensite joomla.conf

Restart the Apache web server.

$ sudo systemctl restart apache2

Step 7: Access Joomla 4 Web Installer

Open your browser type your domain e.g http://your-domain.com  and complete the required steps to finish the installation.

Once the Joomla has been installed, you will get the following screen:

Click on the Open Administrator. You will get the login screen:
