Fresh Install - CentOS7 - FOG 1.5.7 - "database is updated/installed" - blank screen in browser

[InfoOverload]

I have been attempting to install a new instance of FOG onto a fresh install of CentOS 7.
All seems to be going well right up until I get to the following prompt:

 * You still need to install/update your database schema.
 * This can be done by opening a web browser and going to:

   http://<HOST_IP>/fog/management

 * Press [Enter] key when database is updated/installed.

I have seen this problem mentioned before in these forums and I have attempted pretty much ALL of the fixes mentioned.

1. MariaDB service is up and running. I have tried both with blank password and entering a password for root. No difference.
2. HTTPD error logs show NO problems

[root@foghost ~]#  tail -100 /var/log/httpd/error_log

3. HTTPD Access logs shows a single line with a server error 500

<MY WKSTN IP> - - [12/Aug/2019:18:09:50 -0400] "GET /fog/management/ HTTP/1.1" 500 - "-" "Mozilla/5.0 (Windows NT 10.0; WOW64; rv:52.0) Gecko/20100101 Firefox/52.0"

If I “refresh” the page, I get a WHOLE bunch of those same entries.
4. mysql from the command line shows that fog database has not been created, but create/drop of a fog2 db performed as expected. (i.e. it worked to create and delete)

Any help would be appreciated.

Thanks, Dave

OK, well, as an update, It looks like I was banging my head against a bad repo for the php stuff
I walked through the logs of a successful install (by a colleague) and compared them.

All is good now.

Thanks

This tells me that you did not do the prerequisites before installing FOG (maybe).

1. Set selinux to permissive
2. Disable the linux firewall

Do you do these steps?
