Hi Jeremy,

When I take a look at my audit logs, this is the SELinux error I'm seeing
for this file:
> .
type=AVC msg=audit(1425569361.321:11416): avc: *denied* { getattr } for
pid=12404 comm="httpd" path="*/McFrazier/PhpBinaryCql/CqlClient.php*"
dev="vda" ino=1966101 scontext=system_u:system_r:httpd_t:s0
tcontext=system_u:object_r:default_t:s0 tclass=file
type=AVC msg=audit(1425569168.760:11351): avc: denied { read } for
pid=12406 comm="httpd" name="*CqlClient.php*" dev="vda" ino=1966101
scontext=system_u:system_r:httpd_t:s0
tcontext=system_u:object_r:default_t:s0 tclass=file
This is the selinux permissions on that file:
[root@web1:~] #ls -Z /McFrazier/PhpBinaryCql/CqlClient.php
-rwxrw-rw-. apache apache system_u:object_r:default_t:s0
/McFrazier/PhpBinaryCql/CqlClient.php
So I tried giving apache access to that file using this command:
[root@web1:~] #semanage fcontext -a -t httpd_sys_content
/McFrazier/PhpBinaryCql/CqlClient.php
ValueError: Type httpd_sys_content is invalid, must be a file or device type
Seemed logical enough to me, but it doesn't work. I've been googling around
for a while to figure out how to get this to work. But no luck just yet.
If I do a semanage fcontext -l | grep httpd command to see what other
labels might apply I see a lot of different types. But that one seemed to
make the most sense.
Any thoughts?
Thanks
Tim
