Installing Nagios On WHM/Cpanel Server

[sheikhatif]

Hi Support,

I spent about 5 hours to find a solution for viewing nagios web interface since cpanel is using SuPhp bind with Apache. I’ve done the nagios installation so quickly but cpanel apache config. didn’t allow to include “conf.d” folders in “include” list. obviously this command wont work.
#make install-webconf

Everything is seems to be OK but when I open http://ip/nagios
after enter credentials this page appears.

"500 Internal Server Error
The request was not completed. The server met an unexpected condition."

In my nagios.conf

first I made the “include” file entry on main config. file.
#vi /etc/httpd/conf/httpd.conf and include the line on my domain virtual host part.
Include “/home/myuser/conf/nagios.conf”

#vi /home/myuser/conf/nagios.conf and add the following line in it.

in my nagios.conf
ScriptAlias /nagios/cgi-bin "/usr/local/nagios/sbin"

<Directory "/usr/local/nagios/sbin">
# SSLRequireSSL
Options ExecCGI
AllowOverride None
Order allow,deny
Allow from all
# Order deny,allow
# Deny from all
# Allow from 127.0.0.1
AuthName "Nagios Access"
AuthType Basic
AuthUserFile /usr/local/nagios/etc/htpasswd.users
Require valid-user
</Directory>

Alias /nagios "/usr/local/nagios/share"

<Directory "/usr/local/nagios/share">
# SSLRequireSSL
Options None
AllowOverride None
Order allow,deny
Allow from all
# Order deny,allow
# Deny from all
# Allow from 127.0.0.1
AuthName "Nagios Access"
AuthType Basic
AuthUserFile /usr/local/nagios/etc/htpasswd.users
Require valid-user
</Directory>

Any help will be appreciated.

Hey all!

There are a couple of things I would like to say in regard to this. First I will reply to Harsh:

Could you please let me know whether we can install Nagios Server Software on Vistural machine.

In response to this, YES, you can install this on a virtual machine. I have had this working on a Cpanel virtual machine within the last week.



Now on to sheikhatif

in my httpd logs

Unfortunately I had to run the EasyApache system on my virtual machine, and in doing so, I have somehow killed my installation. I am getting the same error in my logs when I attempt to get to my Nagios install now.

If anyone has any way of fixing this, I would greatly appreciate it. I know that it is a permissions issue with relation to suPHP, but for the life of me I have not been able to resolve it. I know that it can work with suPHP because I just had it working, but I can not figure out what broke the page load causing the 500 error.

FYI == My actual monitoring still works, I just can't load the admin...
