Problem restarting nagios

[anaigini45]

Hi,

I am a newbie in Nagios. I installed nagios, and nagiosgraph. It worked initially, when I ran it on the browser (http://localhost/nagios). However, while configuring some *.cgi files for nagiosgraph, I accidently corrupted all those files, including the ones that belonged with nagios. Therefore I wasn't able to view services and hosts, etc etc in nagios.

I removed and reinstalled nagios and its dependencies. However, when I reach the part to restart nagios, I fail to get pass it. This is the error that I receive :

Code: Select all

aigini@aigini-Studio-1555:/usr/local/nagios/etc$ service nagios start
Starting nagios:CONFIG ERROR!  Start aborted.  Check your Nagios configuration.

I even tested nagios cfg with this command :

Code: Select all

aigini@aigini-Studio-1555:/usr/local/nagios/etc$ sudo /usr/local/nagios/bin/nagios -v /usr/local/nagios/etc/nagios.cfg

Things look okay - No serious problems were detected during the pre-flight check

It says no errors. But why do I still get an error when I attempt to start nagios?
I tried looking for nagios error logs but could not find any. Please help.

If you look in /usr/local/nagios/var/nagios.log there should be some information as to why it's failing.

Can you try starting nagios daemon by giving:
#/usr/local/nagios/bin/nagios -c /usr/local/nagios/etc/nagios.cfg -d
I think while recompiling, there might have been some problem with the init script for starting Nagios daemon.
