Killed my Nagios install!

[mhuntbsb]

I had everything working, but I wanted graphing in Core. I was following this:

https://www.openscript.ch/en/articles/h ... n-centos-7

but I only yum -y pnp4nagios but saw it installed:

Package nagios.x86_64 0:4.0.8-2.el7 will be installed

Which then threw this error in the yum:

Running transaction
Installing : nagios-4.0.8-2.el7.x86_64 1/4
warning: /etc/httpd/conf.d/nagios.conf created as /etc/httpd/conf.d/nagios.conf.rpmnew 2/4

I backed out of the graph install, changed all the .cfg's back, and nagios claims to run (from /var/log/nagios):

yet it is giving the "standard error": Whoops!

Error: Could not read host and service status information!
etc etc.

There are two nagios.conf in /etc/httpd/conf.d now! one is just nagios.conf, the other is nagios.conf.rpmnew and there are major differences. The rpmnew has a script alias //usr/lib64/nagios/cgi-bin/" and just the conf is set to /usr/local/nagios/sbin BOTH of which seem valid. I tried moving the .rpmnew out of httpd...I restarted apache and nagios, but still have the same issue. I see the side menu, but there is no data/hosts/etc in the middle.

Any suggestions?

Did you run service httpd restart after removing the RPM apache file? It will be needed in order to reload the configuration.

To add to this, you may need to remove the package it installed as well, but this could lead to issues with other files that may have been modified. Is spinning up a new fresh machine and moving your configuration files over possible?

Lol, that's what I'm doing right now. I did a yum history rollback, got to access denied in the cgi-bin, and finally went home and to sleep. I just finished the reinstall, from boot to Nagios admin login was about an hour. Luckily I snagged all the .cfg's out of objects first. Back up and running.

What is the "normal" and non-system-destroying way to get graphs working?
