Softaculous is a handy add-on for cPanel that gives your users the ability to quickly and nearly effortlessly install web application scripts. You can administer it through WHM, but once it is installed, any of your cPanel users can do one-click script installations. Installing Softaculous is relatively easy. Just follow these steps.
First, you should make sure that your firewall will allow downloads from *.softaculous.com. You will also need to have iconCube loaders enabled for PHP.
From the command line, type:
wget -N http://files.softaculous.com/install.sh
chmod 755 install.sh
You should now be able to login to WHM, navigate to Plugins and find Softaculous – Instant Installs. If all goes well, you should see information about your software and server. Your installation is complete, and your users can now access it from within cPanel according to your settings and hosting plans.
