If SELinux is running on your system, SELinux can deny execution of OvenMediaEngine.

You can choose between two methods of adding a policy to SELinux or setting SELinux to permissive mode. To add a policy, you must apply the SELinux policy file for the OvenMediaEngine service to your system as follows:
$ cd <OvenMediaEngine Git Clone Root Path>$ sudo semodule -i misc/ovenmediaengine.pp$ sudo touch /.autorelabel# If you add a policy to SELinux, you must reboot the system.$ sudo reboot
Setting SELinux to permissive mode is as simple as follows. But we do not recommend this method.
$ sudo setenforce 0
