Broken Nagios Log Server after PHP upgrade

[wat_006]

Hi all,

We're currently using the Trial/Free version of Nagios Log Server. It is the downloadable VM supplied by Nagios. OS of that VM is CentOS 6.7

I attempted to upgrade PHP on the Nagios Log server. This was prompted by a vulnerability scan showing that the version of PHP Nagios Logserver is running was vulnerable. After the upgrade the server was broken. I experienced the following:
-AD integration broken as it was missing files
-Database was offline

I have since rolled the snapshot of the VM back to a workable state, but I still need to know how to upgrade PHP, and even Apache, so that PHP is not running a vulnerable version and that the log server doesn't break.

What steps should we take to to accomplish this goal?

What version of PHP and Apache do you want to upgrade to?

Did you follow any specific guide to do the upgrade which caused it to break? Can you provide a link to the guide?
