Introduction:
Installing Joomla via Fantastico is a huge time saver when you are
working on multiple sites and don’t have time to wait for Joomla’s
install files to upload. I have come across a few posts in the forums
about people having a hard time installing Joomla! into the root
directory of their site. Here is a quick and easy guide to install into
your sites root. Please note, that this is assuming that you do not
have any live sites currently running within your home directory.
Step 1:
Login to Cpanel and click on file manager. Delete the public_html folder and then recreate it.
Step 2:
Close the file manager, click on fantastico & then Joomla (under CMS). Select “New Installation”
to proceed.
Step 3:
Add all your site’s relevant info. Make sure to leave the “Install
in directory” box empty. This will tell the installer that you want
Joomla! installed into your home directory. Thats about it. Complete the
rest of the steps and you’re done
