  2. A wide range of extensions, plugins, and templates for website customization - both visually and in terms of functionality.
  3. Multilingual Support: Joomla is designed to handle websites with multiple languages, making it suitable for international projects.
  4. Regular security updates,  which address and resolve potential vulnerabilities.
  5. Joomla is used for various types of websites, including blogs, e-commerce sites, and many more.
  6. Joomla is used for various types of websites, including blogs, e-commerce sites, and many more.

Joomla is an open-source platform which is built using PHP and MySQL. It is freely available to anyone.

In this tutorial, we are going to show you how to install Joomla 4 on your AlmaLinux 9 server from AlphaVPS.

Installing the LAMP stack

Joomla requires an Apache webserver to serve its content on the internet, PHP for handling almost all of its functionality, and a MySQL database for persisting data.

For a more detailed explanation of the installation process, you can refer to our guide here. Do note that will use the dnf package manager for AlmaLinux 9.

First, we will update the system packages by running the following commands:

sudo dnf update

Install, start, and enable Apache.

sudo dnf install httpd
sudo systemctl enable httpd
sudo systemctl start httpd

You can check the status of Apache by running:

sudo systemctl start httpd

You will receive similar output:

● httpd.service - The Apache HTTP Server
     Loaded: loaded (/usr/lib/systemd/system/httpd.service; enabled; preset: disabled)
     Active: active (running) since Fri 2023-08-04 13:50:22 EEST; 9s ago

             ├─57766 /usr/sbin/httpd -DFOREGROUND
             ├─57767 /usr/sbin/httpd -DFOREGROUND
             └─57768 /usr/sbin/httpd -DFOREGROUND

Aug 04 13:50:22 meta-trader-test httpd[57764]: Server configured, listening on: port 80

To enable http/https access, AlmaLinux 9 requires the ports to be open in the firewall. This can be done by running:

sudo firewall-cmd --zone=public --add-service=http --permanent
sudo firewall-cmd --zone=public --add-service=https --permanent
sudo firewall-cmd --reload

Installing PHP

You can install PHP and all the required extensions by running:

sudo dnf install php php-cli php-fpm php-curl php-mysqlnd php-gd php-readline php-mbstring php-apcu php-xml php-dom php-opcache php-zip php-intl php-common php-bcmath php-json

Confirm the PHP installation by running:

php -v

You will receive a similar output:

PHP 8.0.27 (cli) (built: Jan  3 2023 16:17:26) ( NTS gcc x86_64 )
Copyright (c) The PHP Group
Zend Engine v4.0.27, Copyright (c) Zend Technologies
    with Zend OPcache v8.0.27, Copyright (c), by Zend Technologies

Installing MySQL

Install, start, and enable your MySQL database by running:

sudo dnf install mysql-server mysql
sudo systemctl start mysqld
sudo systemctl enable mysqld

The installation can be confirmed by running:

sudo systemctl status mysqld

and its respective output should look like:

● mysqld.service - MySQL 8.0 database server
     Loaded: loaded (/usr/lib/systemd/system/mysqld.service; enabled; preset: disabled)
     Active: active (running) since Fri 2023-08-04 14:22:15 EEST; 12s ago
   Main PID: 60267 (mysqld)
     Status: "Server is operational"
      Tasks: 39 (limit: 24796)
     Memory: 455.4M
        CPU: 4.724s
     CGroup: /system.slice/mysqld.service
             └─60267 /usr/libexec/mysqld --basedir=/usr

Aug 04 14:22:15 meta-trader-test systemd[1]: Started MySQL 8.0 database server.

Now we will need to secure the MySQL installation by running the mysql_secure_installation shell script.

As of 2022, if you try to run the  mysql_secure_installation script without additional configuration, an error will occur, which will loop the script.
We will prevent this by doing the following:

sudo mysql
mysql> ALTER USER 'root'@'localhost' IDENTIFIED WITH mysql_native_password BY 'your-password-here';
mysql> exit

Now we can safely start the script by running:

sudo mysql_secure_installation

The whole process is visualized below:

Securing the MySQL server deployment.

Enter password for user root:

VALIDATE PASSWORD COMPONENT can be used to test passwords
and improve security. It checks the strength of password
and allows the users to set only those passwords which are
secure enough. Would you like to setup VALIDATE PASSWORD component?

Press y|Y for Yes, any other key for No: 

There are three levels of password validation policy:

LOW    Length >= 8
MEDIUM Length >= 8, numeric, mixed case, and special characters
STRONG Length >= 8, numeric, mixed case, special characters and dictionary                  file

Please enter 0 = LOW, 1 = MEDIUM and 2 = STRONG: 0
Using existing password for root.

Estimated strength of the password: 50
Change the password for root ? ((Press y|Y for Yes, any other key for No) : 

 ... skipping.
By default, a MySQL installation has an anonymous user,
allowing anyone to log into MySQL 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

Remove anonymous users? (Press y|Y for Yes, any other key for No) : 

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? (Press y|Y for Yes, any other key for No) : 

By default, MySQL 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

Remove test database and access to it? (Press y|Y for Yes, any other key for No) : 
 - Dropping test database...

 - Removing privileges on test database...

Reloading the privilege tables will ensure that all changes
made so far will take effect immediately.

Reload privilege tables now? (Press y|Y for Yes, any other key for No) : 

All done!

It is advisable to confirm all of the suggested settings with a y|Y and set your password validation policy to STRONG.

Create a Joomla database and user

We will need to create a database and MySQL user for our Joomla installation.
We can do this by accessing the MySQL CLI and executing the following commands:

mysql -u root -p
Enter password: 
mysql>CREATE DATABASE joomla;
mysql>CREATE USER 'joomla'@'localhost' IDENTIFIED BY 'provide-password-here';
mysql>GRANT ALL PRIVILEGES ON joomla.* TO 'joomla'@'localhost';
It is not mandatory for your database and user to be named joomla or similar. You are able to specify their names as you wish. Simply note the credentials down, because you will need to provide them during the web GUI setup in the later steps.

Install Joomla

Navigate to your webroot directory and download the latest stable release of Joomla /At the moment of making this tutorial, it is 4.3.3/.

You can check the latest Joomla versions at

cd /var/www/html
Some of the utility packages that we are using in this tutorial do not come pre-installed in AlmaLinux 9. For example, nano, wget, unzip can be easily installed with the dnf or yum package managers. 

Unzip the downloaded package with unzip and remove the downloaded package.

sudo unzip
sudo rm

Set the required permissions with the following command:

sudo chown -R apache:apache /var/www/html/
sudo chmod -R 775 /var/www/html/

Setup Apache Virtual Host

Navigate to your Apache webserver directory.

 cd /etc/httpd/conf.d/

Create an Apache virtual host configuration file

sudo nano joomla.conf

and paste the configuration below in it

<VirtualHost *:80>
     DocumentRoot /var/www/html/
     <Directory /var/www/html/>
          Options FollowSymlinks
          AllowOverride All
          Require all granted

     ErrorLog /var/log/httpd/replace-domain-here.com_error.log
     CustomLog /var/log/httpd/ combined
Make sure that you replace the part with your actual domain.

You can check for eventual syntax errors by running:

httpd -t

Everything is fine if you are receiving output, which includes Syntax OK.

Restart Apache.

sudo systemctl restart httpd

Web Setup

The final steps of the Joomla installation are processed via its Web GUI, which should be now accessible. Navigate to your VPS IP or domain via your browser. Some of the possible ways to find out  your IP by running ip addr or curl

If your browser visualized an error, such as the one below, you will need to disable SELinux on your VPS.

You can disable SELinux temporarily /until a reboot/ by running the following commands:

setenforce 0

To disable it permanently, you also need to modify its configuration file.

$ sudo nano /etc/selinux/config

Modify the SELINUX line and set it to disabled.

Proceed with the installer from your browser.

Select the language and provide your domain name.

Create your user and set credentials.

Provide your database credentials. Provide the credentials, which you have set during the MySQL setup process.

Click on the Install button and wait for the process to finish. Once ready, you will be automatically redirected to the login screen.

Log in with your user credentials and that's it. You now have full access to your Joomla installation via its web GUI.
