So I tried many different ways of doing this but I can't seem to get it to work. I have the latest gitlab downloaded on CentOS 7. I changed the external_url on etc/gitlab'gitlab.rb to http://domain.com:987. No luck.
Then I changed the nginx setting listen_port to 987 and still no luck. But port 80 seem to be working fine. I am not sure what I am doing wrong. Can someone please help?
