I need some help getting started on Nagios. When I try to type ./nagios ../etc/nagios.conf, I get the following error(s) (see below). This is a Redhat 8 box with Apache loaded. I did not encounter any problems when I compiled it. Thanks in advance

Bailing out due to errors encountered while running the pre-flight check. Run Nagios from the command line with the -v option to verify your config before restarting. (PID=7375)

I don't know the program, but it looks like a configuration problem. The default configuration may not be OK.

I figured that I have something misconfigured, I was hoping that someone could let me know what that is. Thanks

Maybe post your .conf file? If it's a configuration issue someone will be able to help you after reading it.

There are about 14 conf files, so I am not sure which to post. If I could narrow it down to one then I would post it. Thanks again

The error messages mention 'Website#1', 'Website #2' and 'nt1'. So you should post all the files they're mentioned in.

Hi to all.

Im trying to install Nagios over Redhat 8.0. but when i try to see de Host status and other options, a message goes out saing to me that a security problem whith the CGI is happenning, that i dont have permit to enter to see the information.

I have a Linux Box with RedHat 7.2 and all works fine, no problems at all. But with 8.0 dosent works.

Anybody Knows about an RPM for 8.0???


With respect to the problem of shelby pls, see the cfg files: hosts, services and hostsgroups there is the problem and run from /usr/local/nagios/bin/nagios -v /usr/local/nagios/etc/nagios.cfg, if you have any problem there will be relfected.

Bye,

Xeux

Hey Shelby... do this: in dependencies.cfg put # at the start of all lines, like comentaries in C. Try it!

bye

Thanks, I will give a shot tommorow.

I deleted my dependencies.cfg and did a touch /usr/local/nagios/etc/dependencies.cfg <enter>

Assuming you have installed to default locations... run this command and reply the output here...

/usr/local/nagios/bin/nagios -v /usr/local/nagios/etc/nagios.cfg

still a newbie but i ran into the same problem. whats really cool about nagios is that when you verify the nagios.cfg file it tells you what line in what config file is messed up. very, very nice.

Hi all, I'm new to Linux myself and my first project is Nagios. I'm running Redhat 8 with Apache. I have verified all of my configuration files and even created authorization files for my users, but for some reason when I go to the webpage http://localhost/nagios/ I can't log in. It gives me the log in box and when I put user id and password in it just pops the box back up. I think that possibly Apache is not able to read my htpasswd.users file, but I've gone through the instructions back and forth and have started over 3 times with out any success. I guess I could just run it with out the web interface, but I'm a Windows guy and am not comfortable with that yet. Any ideas?

Sorry to throw this into your post shelby. but I would recommend just as others have, run the verify script it points out every little mistake you have. Thx for any replies.

Sounds like you have not setup your .htaccess files or your web server cant read them.

Take a look at my demo configs page at [url]http://demo.square-box.com[url] If you read the apache section it will tell you all you need to know about setting up authentication on your web server.

The " you are not authorised" messages are probably being generated by your cgi.cfg file

look for lines in your cgi.cfg

use_authentication=1 #use authentication
authorized_for_system_information=someuser #someuser is authorised
authorized_for_configuration_information=someuser #someuser is authorised

You can of course put in an * here and allow anyone to be authenticated and granted access, note this is bad.

Try my nagios tutorial HERE I will update it as i work on it
