Nagios Support Forum

Can you show me the output from:

I think we'll be installing CentOS at this point and just be done with it. I've run the install on a clean CentOS vm and it installed without issue. I believe the problem stems from (not) being registered with RHN, as you had previously suggested. We're managing our systems with Satellite, which registers our boxes with RHN and should associate them with the right core repos. But, technically it's a proxy and it must be restricting access to a repo that's needed. For whatever dumb reason I didn't think of it as being an issue when I read the part in the FAQ about not supporting proxies. It all adds up though, when you look at all the different symptoms. Thanks though, I appreciate all the help.

Just in case this sheds any more light, here's the yum update output...

Is this ok [y/N]:


Also, here are the repos listed after a yum clean all...

Could you, please, run in terminal (as root) these commands and post the outputs of each one:
# rhn_register
# yum repolist
# yum install mysql
# yum install yum postgresql

I was able to get the install to work under Red Hat after disconnecting from Satellite, registering directly with Red Hat and then adding the EPEL repo manually. All dependencies installed after those steps. I removed the following directories and then ran the full install again:
/usr/local/nagiosxi/
/usr/local/nagios/
/etc/nagios/
/etc/nagiosql/
/var/lib/mysql
/var/lib/pgsql/
/var/www/html/nagiosql/

It's now working. Thanks for the help all!

Glad we could help.
