Hello and Welcome to LinuxQuestions,

Did you create the htpasswd file for the Nagios user? And did you configure Apache for Nagios? What version of CentOS are you running and what version of Nagios did you install.

Kind regards,

Eric

Dear vikas.
I have installed nagios and nagios plugins. My boss ordered me to just install nagios on server(not to configure). But when i try my server ip, it gives error. I'm unable to know the error that is there need to install nrpe on my server? or anything else i'm missing.
Thanks for your reply

Hi,

Check if you have a file apache2.conf or httpd.conf in your nagios configuration directory (/etc/nagios ?). That file holds what needs to be configured on Apache in order to access Nagios.

Kind regards,

Eric

Dear Eric
There is no any httpd.conf file in /etc/nagios.
I have another server working properly nagios and there is also no any http.conf file in /etc/nagios.
All other files/configuration are same in both the servers but one (which i installed) not working on nagios. I don't know what is missing..

regards
Shahnawaz Uqaili

Hi,

Do you have Apache (httpd) set up with VirtualHosts? You might need to add a directory statement for your Nagios directory.

Kind regards,

Eric

Sounds like you've forgotten the URL alias for Nagios in your Apache conf.

Hi,

Check if you have a file for it in /etc/httpd/conf.d/ or if not, if you have the directory statement present in /etc/httpd/conf/httpd.conf for your Nagios installation. Have a look at this site for specifications on what to set up.

Kind regards,

Eric

Dear Eric
I have nagios.conf in /etc/httpd/conf.d/ and i don't understand /etc/httpd/conf/httpd.conf file, because there are many other things running on our server like RT and some other applications. should i need to do something in /etc/httpd/conf/httpd.conf file?
Thanks for continuing replying Eric.
Kind Regards
Shahnawaz
