Nagios Support Forum

We are in the process of evaluating Nagios XI.

We successfully ran the manual installation for Nagios XI on CentOS 5.5

However, we are unable to start the Nagios server. Error given below.

[root@ltenav1 etc]# service nagios start
Starting nagios:CONFIG ERROR! Start aborted. Check your Nagios configuration.
You have new mail in /var/spool/mail/root

What does the output of the following command indicate?

[root@ltenav1 etc]# /usr/local/nagios/bin/nagios -v /usr/local/nagios/etc/nagios.cfg

Check your configuration file(s) to ensure that they contain valid
directives and data defintions. If you are upgrading from a previous
version of Nagios, you should be aware that some variables/definitions
may have been removed or modified in this version. Make sure to read
the HTML documentation regarding the config files, as well as the
'Whats New' section to find out what has changed.

[root@ltenav1 etc]#

It sounds like the default object definitions didn't get setup properly. Did you go through all the commands outlines in the manual installation document?

Also, are you running or using any type of proxy software on this server?

We did go through all the commands (./0-yum until ./Z-webroot) outlines in the manual installation document.

Yes we are behind proxy server. Accordingly, we did update the following-

In /etc/yum.conf :
proxy=http://someproxyserver:port/

In /etc/wgetrc :
http_proxy=http://someproxyserver:port/
no_proxy=localhost,127.0.0.0/8,10.0.0.0/8,172.16.0.0/12,192.168.0.0/16

Only then, it started to install all packages/rpm's.

After a fresh installation, are we expected to update the nagios.cfg file. If yes, then could you please send us a sample nagios.cfg file. There is no information on this in the Manual Installation Document.

Did you re-run all the scripts after configuring things for your proxy?

In particular, it sounds like the configure import failed. This is accomplished with scripts that issue wgets to localhost. These scripts are kicked off by the following step in the install:
You might be able to just re-run that particular command to get things imported.

We don't see an issue with it... but here are the logs for you to trace ....

I'm noticing there may have been some problems with postgresql installing or starting correctly. Check the following:

service postgresql status
service postgresql restart

If it's not installed then I'm guessing that had an issue with the proxy. See if you can get it installed if it isn't there already, then try running through the install scripts again.

Since the db_servertype=mysql in ndo2db.cfg, shouldnt Nagios use MySQL DB? Does nagios require both Postgress and MySQL?

Anyways,here is the status from the commands:
