If you have set up a web hosting account, installing Joomla includes four tasks.
The installation process involves several steps that include:
Check with your web hosting provider to make sure that your hosting is technically eligible for Joomla version you are planning to install. Always try to install latest version of Joomla for more secure and feature-rich website.
Download the latest version of Joomla Full Package (and not upgrade package).
Use cPanel file manager or FTP client to upload downloaded zip file to your web hosting directory you wish to install Joomla.
You can perform this step in parallel with the above step 3. While your Joomla package is uploading, you can work with your database. This has three sub-steps:
Extract the zip file that you have uploaded in the step 3.
Open your website directory where you have extracted Joomla files in any browser (Google chrome recommended). You will see the beginning of your Joomla installation.
The installation of Joomla! takes place using screens. Each screen is accessed by completing the information requested on the previous one and then by executing a Next or Install action.
Screen 1: Main Configuration - Add the site name and the super user administrator information.
Screen 2: Database Configuration - Connects the installation to a specific database and identifies the assigned user. Use the details from the step 4 above to fill username, password and database name. Then, click Next. This password is not required anymore.
Final: Nothing much to be done here. You can choose to install sample data, but it is not required and I don't recommend it. Just click Install. You will see following message:
Congratulations! Joomla! is now installed
Click on Remove installation folder. This is important for security purpose. Also, delete the zip file you uploaded in the step 3.
Simple! You have just finished installing Joomla. Now you can login to your administrator panel using log in details created in step 3.
