Installation on RHEL6: RHN error

[DWZ]

Hi there,

I'm attempting to install cPanel on a RHEL6 box we have here; however when attempting to start the installation cPanel throws an error and the installation terminates:

[[email protected] home]# sh latest

My problem, however, is that as far as I can tell, the server already is registered with RHN. If I follow cPanel's instructions and run /usr/sbin/rhn_register, I get a warning that the server is already registered.

If I run rhn_check I get a 0 exit code (suggesting RHN is configured correctly and working):

[[email protected] ~]# rhn_check -v
[[email protected] ~]# echo $?
0

Has anyone got any idea what might be wrong?

Hello

There is an additional step to take when installing cPanel on RHEL. Before you install cPanel & WHM on a Red Hat Enterprise Linux v.6 server, you must subscribe the server to the Red Hat Enterprise Linux 6 Server - Optional (RPMs) channel. To subscribe to the RHEL Server - Optional (RPMs) channel, run the following command:

# subscription-manager repos --enable rhel-6-server-optional-rpms

This is documented at:

cPanel Installation - Configuring OS

If the issue persists after following this step, please provide us with the output of the following command:

# yum check-update

Thank you.

Just thought I'd post an update in case anyone has the same problem and stumbles across this thread: The problem ended up being that we had the RPMs for subscription-manager installed; but it wasn't configured. This is because we were in fact using Satellite. So, as far as I can tell, cPanel noted the subscription-manager RPM was installed, and made an assumption we weren't using Satellite, which wasn't the case.

So, the fix was simply just to 'yum remove subscription-manager'
