I am very new to Linux. So, any suggestions are going to have to be spelled out quite basically for me to follow them. I am trying to install an RPM that should allow me to install NAGIOS on a CentOS 5 machine that I just installed.

The problem I'm running into is this. After typing in the following command as root in a terminal window to add a repository to yum so I can install nagios I get this:

[root@localhost ~]# rpm -Uhv http://apt.sw.be/redhat/e15/en/x86_64/rpmforge/RPMS
//rpmforge-release-0.3.6-1.e15.rf.x86_64.rpm
Retrieving http://apt.sw.be/redhat/e15/en/x86_6...mforge-release

error: skipping http://apt.sw.be/redhat/e15/en/x86_6...S//rpmforge-re

warning: u 0xac65520 ctrl 0xac68e10 nrefs != 0 (apt.sw.be http)


Any thoughts on how I should proceed with an error like this?

Just as a reference I was using this guide to help me with the Nagios install....

Hello and Welcome to LinuxQuestions,

Have a look at this site:
http://wiki.centos.org/HowTos/Nagios

It lists all you need in very easy steps to install Nagios on your CentOS machine.

Kind regards,

Eric

Unfortunately I have already been to that site, when I enter in their command to install NAGIOS (see below)
[me@mymachine ~] yum install nagios nagios-plugins nagios-plugins-nrpe nagios-devel

I get a message about "NO PACKAGE NAGIOS AVAILABLE" and so on for each of the plugins as well. I assumed I needed the repositories installed for the above yum install line to work. Is that not the case?

Thanks

Did you run:
before trying to install the packages? Have you already installed other packages using yum? What do you have listed as repositories in your directory:
or
Kind regards,

Eric

I had not run "yum update". I just did that and its installing 90 updates I assume? I'll try the nagios install after that and see if it works. Back in a moment...

Hi,

OK, that looks promising. The update option synchronizes to the repositories. So most likely after the updates you can install Nagios the normal way. Let's hope so. Looking forward to your next post.

Kind regards,

Eric

Ok ran the updates then ran the Nagios install command and got the same message. "No Nagios Package"

In my /etc/yum.repos.d/ folder I have two files.
CentOS-Base.repo
CentOS-Media.repo

Not sure what that means?

Thanks!

Hi,

In the meantime I've been searching Google in order to find what repo has to be added so that you can install Nagios. I found this site:
RPMForge repository

That repository apparently contains the Nagios packages. Follow the instructions on that site to add the repository to your yum configuration and after that it should work.

Kind regards,

Eric

That did it!

First I downloaded the package to my root desktop.
http://packages.sw.be/rpmforge-relea....rf.x86_64.rpm

I had to run this command: Install DAG's GPG key

rpm --import http://dag.wieers.com/rpm/packages/RPM-GPG-KEY.dag.txt

Then I ran this one: Install the package

rpm -i rpmforge-release-0.5.1-1.el5.rf.*.rpm (Ran this after switching directories to my desktop where I downloaded the file)

Then ran yum-check update and it snagged updates. Then I was able to install Nagios by running my previous command.

Thanks so much for the help!

That's great news. Glad you got it working. Happy to be of assistance. If you consider this solved then please mark it as such using the Thread Tools.

Kind regards,

Eric
