What is WHM?

Last updated: March 28, 2011

WebHost Manager (WHM) is a browser based tool used by system administrators and resellers to manage services and aspects of the server that would usually require command line interaction. It is also used to create and manage hosting accounts on a web server. WHM listens on ports 2086 and 2087 (secure) by default.

Usually WHM is access using the root account but WHM is also accessible to users with reseller privileges. Reseller users of WHM have a smaller set of features than the root user, generally defined by the server administrator. These features usually only affect the resellers customers accounts rather than the server as a whole. From WHM, the server administrator can perform maintenance operations such as compile Apache and upgrade RPMs installed on the system as well as add, suspend or terminated reseller or individual accounts.
