Configuring PHP and suEXEC from the Command Line cPanel Print

You may see "The EasyApache4 Technology Preview needs to be configured via command-line tools. The WHM user interface does not currently support this Technology Preview." when using easyapache4

 /usr/local/cpanel/bin/rebuild_phpconf --current 5 suphp suphp 1
