Install Softaculous in cpanel Server
first you need to make sure that ionCube already installed, you just run this command to verify if
installed php -v
if ionCube installed then you need to follow the below commands
cd /usr/local/cpanel/whostmgr/docroot/cgi
wget -N http://www.softaculous.com/ins/addon_softaculous.php
chmod 755 addon_softaculous.php
Now go to : WHM > Plugins (Add-Ons on older versions than 11) > Softaculous – Instant Installs
then few seconds and will see the installation already done successfully
Thank you
