Apache proxy for nagios

Posted: Tue Jun 10, 2014 2:52 am

I want to proxy nagios using apache virtual host: eg. nagios.example.com
My apache is working on 192.168.0.133, my nagios is on 192.168.0.31
I have tried to use some examples from net but i have problem with /nagios/cgi-bin

my config:

Code: Select all

<VirtualHost 192.168.0.133:80>
    ServerName nagios.example.com
    DirectoryIndex index.cgi

    Options MultiViews Indexes SymLinksIfOwnerMatch IncludesNoExec FollowSymLinks

    LogLevel debug
    CustomLog /var/log/httpd/nagios-ssl.log combined
    ErrorLog  /var/log/httpd/nagios-ssl.error

    ProxyPass / http://192.168.0.31/nagios/
    ProxyPassReverse / http://192.168.0.31/nagios/

    ProxyPass /nagios/cgi-bin http://192.168.0.31/nagios/cgi-bin
    ProxyPassReverse /nagios/cgi-bin http://192.168.0.31/nagios/cgi-bin
</VirtualHost>
I can access to main nagios page using proxy, but i can't use link on site ( every links in left panel have wrong address :The requested URL /nagios/nagios/cgi-bin/status.cgi was not found on this server.)

Can anybody tell me what I'm doing wrong ? or what is correct config of apache proxy virtual host ?
Thanks a lot

What do your apache logs show?

Lets look at your running vhost config:

I don't have bigger problems with proxying to joomla, bugzilla, nconf, own wiki page, and zimbra mail system.
I have problem only with nagios (but i still don't know why)

My conclusion:
Links in left panel leads me to wrong directory :
Services - > (http://nagios.example.com:81/nagios/cgi ... i?host=all) give me below result:

Code: Select all

Not Found
The requested URL /nagios/nagios/cgi-bin/status.cgi was not found on this server.
Apache/2.2.15 (CentOS) Server at 192.168.0.31 Port 80


But when will I do modifications (delete nagios from url) (put http://nagios.example.com:81/cgi-bin/st ... i?host=all) i can see content of page (but without good formating: no background, no colors, only text)

We're not really an Apache forum, but we'll help with what we can. However you might want to try posting on an Apache forum since they would be more knowledgeable about it.

I'm not too familiar with the proxy settings, but maybe you have your mapping set incorrectly? That /nagios/nagios/ part makes me think it's processing the rewrite rule twice, so your links are failing. If you just type in the IP address to the address bar does it still bring you to the Nagios web page? If so you might need to remove a /nagios/ from your proxy somewhere since the redirection is already being done.

Many thanks for suggestions - I tried to change combination of proxypass directives and it looks like everything is working.
It seems that previos configuration does not prevent dual rewrite - warning "Sharing worker 'http://192.168.0.31/nagios/' instead of creating new worker 'http://192.168.0.31/nagios/cgi-bin' " has big sesne.

I think we can close this topic.

Fixed config (working)

Code: Select all

    ProxyPass /nagios/stylesheets/  http://192.168.0.31/nagios/stylesheets/
    ProxyPassReverse /nagios/stylesheets/  http://192.168.0.31/nagios/stylesheets/
