Describe your question in as much detail as possible:
My server is like 13 years already, using latest nginx on centos 8. I want to install gitlab using omnibus but it seems it makes my current nginx not to work correctly. Do i need other applications in order to run it on my independent nginx?
What are you seeing, and how does it differ from what you expect to see?
My goal is to use my already installed nginx instead the bundled one from omnibus
Thanks for taking the time to be thorough in your request, it really helps!
