Installation of nagios core 3.4.1 on RHEL 5.8 fails

[Hiroshi]

Hello All,

I'm trying to install nagios-3.4.1 & nagios-plugins-1.4.15 on a RHEL 5.8 server. I followed all the instructions from:

http://www.thegeekstuff.com/2008/05/nag ... on/#more-5

The instructions were for installation and configuration of nagios-3.0.1 & nagios-plugins-1.4.11, but everything seemed to work for the newer version as well.

After I finished all the steps and tried adding nagios to the startup routine, I got the following error:

# chkconfig --add nagios
error reading information on service nagios: No such file or directory

Apparently the whole thing has failed, but I have no idea where to begin troubleshooting. The strange thing is the fact that when I try to verify for the consistency of the config file, I get no errors (please see below):

[root@dns2 Downloads]# /usr/local/nagios/bin/nagios -v /usr/local/nagios/etc/nagios.cfg

Everything's fine, the guide you followed just forgot to tell you to run 'make install-init' during installation. Go back and run the command and it should work.

[Hiroshi]

agriffin, thanks so much for the quick reply. It took me a while to implement the change, as I'm the only Unix/Linux SA for a mid-size city in California, and I do it all: Backups, SAN, Solaris, Linux, etc.

Anyhow, after running 'make install-init' command, everything else worked like a charm. As a final test, when I opened a browser and tried going to "http://localhost/nagios" with nagiosadmin as user, I got the following error:

Forbidden
You don't have permission to access /nagios/ on this server.
Apache/2.2.3 (Red Hat) Server at localhost Port 80

Could it be because of wrong password (I may have forgotten it) or is it something else. Could I reset the password by running "htpasswd -c /usr/local/nagios/etc/htpasswd.users nagiosadmin" command again?

Thanks again,
Hiroshi

That may help, give it a try.

[Hiroshi]

Nope, that didn't do it; just to be on the safe side, I repeated the following steps, and still same error about "You don't have permission to access /nagios/ on this server."

[root@localhost]# make install-webconf
[root@localhost# htpasswd -c /usr/local/nagios/etc/htpasswd.users nagiosadmin
New password:
Re-type new password:
Adding password for user nagiosadmin

Is there anything else I can try? Please advise; many thanks.

Hiroshi
