Thank you Richard. I have shared your post in my thread in the CentOS forums.

For now, to work around the issue, CentOS forum user sercan has provided the following commands to create a new SELinux policy for Nginx. I've tested it on two of my servers and it works.

- Make sure you have the policycoreutils-python package installed (yum install policycoreutils-python), then run the following 3 commands:

1. grep nginx /var/log/audit/audit.log | audit2allow -m nginx > nginx.te
2. grep nginx /var/log/audit/audit.log | audit2allow -M nginx
3. semodule -i nginx.pp
