Re: appdynamics php agent prevented by SELinux

Well, I was having a heck of a time with the rpm install in terms of
customizing the install directory.

So I thought the easy way out might be to go for a source install. Which I
tried and this was the output from the install:

[root@web1:/opt/AppDynamics/appdynamics-php-agent] #./install.sh
appd.jokefire.com 443 beta.jokefire.com "Web Front End" web1.jokefire.com

That seemed a little more like it! At least it's out of the way and in a
directory that's a little easier to control - /opt. And also I was able to
specify some important information like what appd controller I was using
etc that I wasn't using a source install.

However, I found that really strange SELinux just followed me to the new
location. Sigh...

Why is that odd? Well mainly because I have SELinux off at the moment.

[root@web1:~] #getenforce 0
Permissive

I also tried a restorecon -R -v /opt/AppDynamics. But even after doing that
the SELinux errors in the output of systemctl status httpd are still
happening.

And if I take a look at the SELinux permissions on that directory, this is
what I have:

[root@web1:~] #ls -lZ /opt/ | grep -i appd
drwxr-xr-x. apache apache unconfined_u:object_r:usr_t:s0   AppDynamics

[root@web1:~] #ls -lZ /opt/AppDynamics/
drwxrwxr-x. apache apache unconfined_u:object_r:usr_t:s0
appdynamics-php-agent
drwxr-xr-x. apache apache unconfined_u:object_r:usr_t:s0   var

Anyone have any ideas on how I can beat this problem?

Thanks!!
Tim
