Install Joomla

Steps

Download Joomla from downloads.joomla.org. The zip file will be saved to your ~/Downloads folder.
Unzip Joomla_x.x.x-Stable-Full_Package.zip. This creates a ~/Downloads/Joomla_x.x.x-Stable-Full_Package folder.
Move the contents of that folder to /Applications/MAMP/htdocs. If asked whether to overwrite the existing index.php, click Replace.
In MAMP, click WebStart in the toolbar, then open phpMyAdmin from the tools menu.
Create a new database named joomla.

The message “No tables found in database.” is expected – Joomla creates its tables automatically during installation.
In MAMP, click WebStart, then click My Website. The Joomla installation wizard opens automatically.
Select your installation language and enter a site name.
Set up your administrator login.
Enter the database details:

Field Value
Database Type MySQLi
Host Name localhost
Username root
Password root
Database Name joomla
Table Prefix jo_ (or any prefix you choose)
Wait for the installation to complete.
Installation is complete.
