Hi,

I have configured nagios on my local VM machine and i got no error

Total Warnings: 0
Total Errors: 0

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

But when i am unable to start nagios
# service nagios start
nagios: unrecognized service

Can anybody help me to fix this issue ?

Thanks in advance

Can you show me the output of the following:

Code:

ls -al /etc/rc.d/init.d/nagios*

---------- Post added 03-23-11 at 10:29 PM ----------

And what distro are you using?

# ls -al /etc/rc.d/init.d/nagios*
ls: /etc/rc.d/init.d/nagios*: No such file or directory

Create a new file called nagios in /etc/rc.d/init.d/ with the following command and chmod it to 755:

Code:

touch /etc/rc.d/init.d/nagios

chmod /etc/rc.d/init.d/nagios 755

Then use gedit or any program to edit the file, and paste the following contents into it and save it:

Code:

#!/bin/sh

Hi rajesh,

I think you forget this step while compiling nagios

Quote:

make install-init

once you install init you got that init config file so then you can able to start the nagios.!!!

Thanks for your reply.I can able to start nagios service.But when i try to browse http://localhost/nagios. I am getting error as

Not Found

The requested URL /nagios was not found on this server.
Apache/2.2.3 (CentOS) Server at localhost Port 80

Any idea ?

I found both apache and nagios are running now.

Thanks

Hello,

You need to configure Apache in order to be able to access Nagios. Have a look at this documentation.

Kind regards,

Eric

Hi rajesh,

Please while compiling do with complete documents, for nagios in nagios forums itself most of the details available, so please go through documents first

http://www.ziddu.com/download/143199...agios.doc.html

Download this doc, i hope its really useful for you, with out entry in Apache also its work fine, please disable the SELINUX context and try.

I have a doubt whether need to do nagios installation on /etc or we can do any location like / ?

Hi rajesh,

Mark your thread as [SOLVED] if your questions are answered, and give reputation if you feel like it.

Hey anishkumarv, way to copy part of my signature into your own. At least edit it a bit to change it up next time.
