Joomla is a popular open-source content management system (CMS) that allows users to build websites and online applications. It is written in PHP and uses a MySQL or MariaDB database to store content. Joomla provides a user-friendly interface for managing content, as well as a wide range of extensions and themes to customize the website's design and functionality.

To install Joomla on CentOS 8, follow the steps below:

1. Step 1: Set up LAMP stack
   • Install Apache web server: sudo dnf install httpd
   • Install MariaDB database server: sudo dnf install mariadb-server
   • Install PHP and required extensions: sudo dnf install php php-mysqlnd php-json php-xml php-gd php-mbstring php-zip
   • Start and enable the services: sudo systemctl start httpd and sudo systemctl enable httpd
2. Step 2: Configure MariaDB
   • Secure the database installation: sudo mysql_secure_installation
   • Create a new database and user for Joomla:
     • Log in to the MySQL shell: sudo mysql -u root -p
     • Create the database: CREATE DATABASE joomladb;
     • Create the user: CREATE USER 'joomlauser'@'localhost' IDENTIFIED BY 'password';
     • Grant privileges to the user: GRANT ALL PRIVILEGES ON joomladb.* TO 'joomlauser'@'localhost';
     • Flush privileges and exit the shell: FLUSH PRIVILEGES; and EXIT;
3. Step 3: Download and extract Joomla
   • Download the latest version of Joomla: sudo dnf install wget and wget https://downloads.joomla.org/cms/joomla38/3-9-28/Joomla_3-9-28-Stable-Full_Package.tar.bz2
   • Extract the package: tar xvf Joomla_3-9-28-Stable-Full_Package.tar.bz2
   • Move the extracted files: sudo mv Joomla_3-9-28-Stable-Full_Package /var/www/html/joomla
   • Set proper permissions: sudo chown -R apache:apache /var/www/html/joomla
4. Step 4: Complete the Joomla installation
   • Access the Joomla web installer by opening a web browser and entering your server's IP address or domain name followed by "/joomla" (e.g., http://your_server_ip/joomla)
   • Follow the on-screen instructions to provide the database details (database name, username, and password) that you created earlier.
   • Once the installation is complete, remove the installation directory: sudo rm -rf /var/www/html/joomla/installation
5. Step 5: Configure Apache virtual host

     
   
       ServerName your_domain_or_ip
       DocumentRoot /var/www/html/joomla
       ErrorLog /var/log/httpd/joomla_error.log
       CustomLog /var/log/httpd/joomla_access.log combined
   
   

   • Create a virtual host configuration file: sudo nano /etc/httpd/conf.d/joomla.conf
   • Add the following content to the file:
   • Save the file and exit the text editor.
   • Restart Apache for the changes to take effect: sudo systemctl restart httpd
6. Step 6: Access Joomla
   • Open a web browser and enter your server's IP address or domain name in the address bar.
   • You will see the Joomla site that you have installed.

That's it! You have successfully installed Joomla on CentOS 8. You can now start building your website or application using Joomla's powerful features and extensibility.
