Joomla is a popular, open-source content management system (CMS) that allows you to create powerful websites and online applications. Its user-friendly interface, extensibility, and vibrant community make it a top choice for website development. This guide is designed to help beginners install Joomla on Ubuntu 23.04, providing detailed instructions and real command-line examples for each step of the installation and configuration process.

Step 1: Update Your System

Always start by updating your system’s package list to ensure all your system packages are up-to-date. This helps avoid potential conflicts during the Joomla installation.

sudo apt update && sudo apt upgrade -y

Step 2: Install the LAMP Stack

Joomla requires a web server, a database, and PHP to function. Installing a LAMP (Linux, Apache, MySQL, and PHP) stack is the first step.

1. Install Apache:

   sudo apt install apache2 -y

2. Install MySQL:

   sudo apt install mysql-server -y

After installing MySQL, it’s recommended to run the mysql_secure_installation script to secure your database server.

3. Install PHP and necessary extensions: Joomla requires PHP and several PHP extensions to operate. Install PHP and the extensions with:

   sudo apt install php libapache2-mod-php php-mysql php-cli php-json php-curl php-zip php-gd php-xml php-mbstring -y

Step 3: Create a MySQL Database and User for Joomla

Joomla stores its site data in a MySQL database. You need to create a database and a user with the necessary privileges.

1. Log in to MySQL:

   sudo mysql -u root -p

2. Create a database for Joomla:

   CREATE DATABASE joomla_db;

3. Create a MySQL user and grant privileges: Replace your_password with a secure password.

   CREATE USER 'joomla_user'@'localhost' IDENTIFIED BY 'your_password';
   GRANT ALL PRIVILEGES ON joomla_db.* TO 'joomla_user'@'localhost';
   FLUSH PRIVILEGES;
   EXIT;

Step 4: Download and Install Joomla

With your LAMP stack ready and the database set up, you can now download and install Joomla.

1. Download the latest Joomla version: Navigate to the /tmp directory and use wget to download the latest Joomla package.

   cd /tmp
   wget https://downloads.joomla.org/cms/joomla3/3-9-28/Joomla_3-9-28-Stable-Full_Package.zip

2. Unzip the Joomla package to the web root directory:

   sudo unzip Joomla_3-9-28-Stable-Full_Package.zip -d /var/www/html/joomla

3. Set the correct permissions:

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

Step 5: Configure Apache for Joomla

Create a new Apache virtual host configuration for your Joomla site.

1. Create a new Apache configuration file for Joomla:

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

2. Add the following configuration, adjusting ServerAdmin and ServerName as necessary:

   <VirtualHost *:80>
       ServerAdmin admin@example.com
       DocumentRoot /var/www/html/joomla
       ServerName example.com

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

       ErrorLog ${APACHE_LOG_DIR}/error.log
       CustomLog ${APACHE_LOG_DIR}/access.log combined
   </VirtualHost>

3. Enable the site and Apache rewrite module:

   sudo a2ensite joomla.conf
   sudo a2enmod rewrite
   sudo systemctl restart apache2

Step 6: Finalizing Joomla Installation

Now, navigate to your website in a web browser to complete the Joomla installation through its web-based setup wizard. Enter the database details you created earlier, and follow the prompts to configure your Joomla site.
