How to Install and Configure Joomla on RHEL 9

LAMP is an open-source web development software stack wherein Linux is the operating system, Apache is the web server, MySQL is an RDBMS, MariaDB is a community-developed fork of MySQL, and PHP is the object-oriented scripting language.

Prerequisites

Before you begin the installation of Joomla, ensure you have the following:

• A RHEL 9 server is up and running.
• You will need root (sudo) privileges to install the necessary packages and configure services.
• It’s recommended to have a domain name pointed to your server’s IP address for accessing your Joomla site.

Step 1: Setting System Hostname

To set the hostname to joomla.tecmint.com on RHEL 9, use the following hostnamectl command.

sudo hostnamectl set-hostname joomla.tecmint.com
hostnamectl

Next, open the /etc/hosts file to map the hostname to your server’s IP address.

sudo nano /etc/hosts

Add the following line to associate the hostname with your server’s IP address (replace your_server_ip with your actual IP address).

192.168.122.31  joomla.tecmint.com

Step 2: Installing LAMP Stack

Joomla requires a web server (Apache) to serve its web pages, a database (MySQL) to store its content, and PHP along with the necessary extensions to function properly.

To install the LAMP stack, run the following command.

sudo dnf install httpd mariadb-server php php-mysqlnd php-xml php-mbstring php-json php-zip php-gd php-intl

Once the LAMP stack is installed, start the Apache and MariaDB service and enable it to start on boot.

sudo ystemctl start httpd mariadb
sudo systemctl enable  httpd mariadb

Next, you need to secure the MariaDB installation by running the MySQL security script, which will ask you to set the root password, remove anonymous users, disallow root login remotely, remove the test database, and reload privilege tables.

sudo mysql_secure_installation

Once you have your MariaDB installation, you can connect to the MySQL server and create a new database and user for Joomla.

sudo mysql -u root -p
CREATE DATABASE joomla;
CREATE USER 'ravi'@'localhost' IDENTIFIED BY 'rig!43B#';
GRANT ALL PRIVILEGES ON joomla.* TO 'ravi'@'localhost';
FLUSH PRIVILEGES;
EXIT;

Next, you need to configure the following required PHP settings in the /etc/php.ini configuration file.

sudo nano /etc/php.ini

Find and update the following settings in the php.ini file:

memory_limit = 256M
upload_max_filesize = 30M
post_max_size = 30M
max_execution_time = 30

Step 3: Downloading and Configuring Joomla

Now that we have our web server, database, and PHP environment ready, we can proceed to download and configure Joomla by visiting the Joomla download page or using the following wget command to download it directly in the terminal.

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

Next, extract the Joomla package to the web root directory.

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

Now change ownership of the directory with user and group “apache” recursively with the below command.

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

Step 4: Configure Apache for Joomla

To make Joomla accessible, you’ll need to configure Apache to serve the Joomla directory.

sudo nano /etc/httpd/conf.d/joomla.conf

Add the following configuration.

<VirtualHost *:80>
    ServerAdmin [email protected]
    DocumentRoot /var/www/html/joomla
    ServerName your_domain_or_IP
    <Directory /var/www/html/joomla>
        Options Indexes FollowSymLinks
        AllowOverride All
        Require all granted
    </Directory>
    ErrorLog /var/log/httpd/joomla-error.log
    CustomLog /var/log/httpd/joomla-access.log combined
</VirtualHost>

Replace your_domain_or_IP with your domain name or server IP address.

Test the Apache configuration for syntax errors and restart Apache to apply the new configuration.

sudo apachectl configtest
sudo systemctl restart httpd

Next, you need to open port 80 for HTTP and port 443 for HTTPS on firewalld.

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

Step 5: Complete the Joomla Installation via Web Browser

Now that everything is set up, you can complete the Joomla installation through your web browser by going to the following URL.

http://your_domain_or_IP

Follow the on-screen instructions to complete the installation:

Once the installation is complete, you’ll see a success message. You can then log in to the Joomla admin panel using the admin account you created.

Conclusion

You’ve successfully installed Joomla on RHEL 9, now you can create and manage your blog, a business website, or a large e-commerce site.
