    Hi all,

    I am not familiar with cPanel nor a user at this stage but I am trying to understand the limitations of cPanel and WHM. I understand that cPanal is really the customer interface where it can control the settings of its website. This module sounds great.

    As far as I understand, WHM is the administrator interface where he/she will be able to manage one server only. It means that the administrator needs to keep track of where a web site is installed if the customer requires some support.

    Is there a way to manage all the accounts from one WHM interface or do you need to install one per server? What happens if you have one server managing MySQL, another one the FTP space and another one again managing the mail? Would SHM be compatible with this structure?

    Thanks in advance for your answers

    WHM is used for running both the server and cpanel and there is one instance of WHM per server; you actually access it via a domain name or IP on the server: eg: or

    To log into WHM for an account, you do need to keep track of where the account is held; but frankly this doesn't get hard until you get bigger and is something you'll have time to deal with then. Some workarounds are that you can also use the domain name to access WHM (, or just use a whois facility, or ping it to see which IP is involved. We use internal utilities for this purpose (to show us where an account is held, and to do some management) and I have toyed with the idea of productizing it and releasing it, but it's a lot of work to do so.

    There is currently no way to manage all accounts on multiple servers from one WHM interface.

    WHM/Cpanel aren't really designed for this structure and I don't think that's a disadvantage - you can get into a lot of needless complication with a structure like this, which really only applies for large, high volume/load accounts which can be hosted differently or indeed put on dedicated servers. The model is very much all-in-one and it keeps things simple and generally works pretty well. I personally think the games that, for instance, Hsphere gets into (with accounts spread over multiple servers) get very confusing and complex and don't add much reliability or performance and in fact may make things less reliable (more complex is always less reliable, in IT).

    Having said that, you can run MySQL on another server and I know that works for some people. Of course, FTP space needs to be on the webserver for obvious reasons! Most load for email comes from excessive spam and there are other ways to reduce the load there - nolisting and ASSP are two strategies that come to mind.
