Loris: Confirm that Apache can be configured by the install script for CentOS

[johnsaigle]

OK well it sounds like further testing should be done to make sure that Apache can be automatically configured by the install script for CentOS. I'll make an issue for it.

@maltheism could you actually check this issue, during your minor release testing? That would be super useful to diagnose next steps.

Hi @johnsaigle and @christinerogers. The install.sh script gives me this output:

Generating autoload files
CentOS distribution detected.
Would you like to automatically create/install apache config files? (In development for CentOS 6.5) [yn] y

I'm guessing the httpd apache module for php is missing. I don't really know what to do for fixing this issue. Seems like centos 7 specific.

Okay so maybe this is something helpful for the issue

Okay I think the solution is this command:
sudo yum --enablerepo=remi-php72 install php
for installing php72.

That changes the Repository to be "remi-php72" instead of "remi-safe" and solves the php_value error inside httpd. The final result will be a clean install.sh output of handling the apache configuration.

[maltheism]

https://github.com/aces/Loris/pull/5492 was merged and addressed an issue. The install.sh script does create the apache file on centos but the user does have to configure it. I think that's intended.
