How to install Apache Tomcat using WHM
Apache Tomcat's installation will require an Apache/PHP recompile on your server. Acenet strongly suggests processing an Apache/PHP recompile during your server's non peak hours. The reason being because an Apache/PHP recompile may cause sporadic performance issues on your server while it's processing and it takes about an hour for the recompile to complete.
 Log into your server's WHM as root.
 Click on 'EasyApache (Apache Update)' which is under the 'Software' section.
 Ensure 'Previously Saved Config (** DEFAULT **)' is selected.
 On the 'Short Options List' page, check the box next to 'Tomcat'.
 Wait for the recompile to complete. (usually takes about an hour)
