Good advice.  As I suspect the problem is with SELinux.

So I tried an access.  What follows is the access_log entry, the 
error_log entry and the 3 entries in the audit.log: - - [28/Dec/2016:11:59:10 -0500] "GET /~rgm/family/ 
HTTP/1.1" 403 214 "-" "Mozilla/5.0 (X11; Fedora; Linux x86_64; rv:50.0) 
Gecko/20100101 Firefox/50.0"

I will say that after enabling selinux on this image per the 
instructions of the team doing the Centos7-arm builds, I got the 
following messages when I did things like 'setsebool -P 
httpd_enable_homedirs on':

[ 2273.047017] SELinux:  Class binder not defined in policy.
[ 2273.052531] SELinux: the above unknown classes and permissions will 
be allowed

So something may well not be right with my SELinux.
