Nagios and Plesk

[dez]

Hi,
I've installed nagios on centOS 6.5 with plesk installed too and I keep getting the "Internal server error" when I try to access to "host".
I've tried to install nagios in the plesk directory like /var/www/vhosts/###/nagios-dev/ but it's not working either.
I also disabled SELinux.
I can't find anything wrong in the different log

I've already installed nagios on a server without plesk, and it works, si I presumed the error is due to plesk.

Thanks in advance

We've seen a lot of issues with things like PHPMyAdmin, cPanel, Plesk, etc.

These seem to suggest that a recent python upgrade has broken compatibility, but my Plesk admin experience is nil so that's just an educated guess.

Hello Together
i searched very long to solve my different problems with installing Nagios on my Webserver with plesk.
There are only a few things to do that it works. but it was had to find them.

Here is a short HowTo:
[*] download the Core and the Plugins from nagios.org
[*] make a copy of your "/etc/group" because some installation-routines are removing your apache from his groups
[*] install the Nagios - Core by the manual on nagios.org
[*] at the point with "make install-webconf" you have to copy the content of the config-file /etc/httpd/conf.d/nagios.conf into your apache-config in the Plesk-Domain-administration (HTTP and HTTPS)
[*] disable the Apache-Module "suexec" on the Plesk-Server-Administration / Apache... - i know that it is used for security. but i don't found a sollution to allow the execution of cgi-scripts in /usr/local/nagios/sbin/ and so i always received the SERVER ERROR 500. Some said that i have to compile it ner. But i don't know if this works with PLESK. But my Server only allows connections from my own adress so i thing that i can accept this "security-problem"
[*] if you are using nconf for administration, you should add the user "nagios" to the group psaserv, too. or you don't have access to the Configs in the Webfolder.

Thanks for sharing your solution! Do you mind if we mark this as resolved then?
