Why can't I change the owner of a file in Centos?

Question

linux

I have an nginx error "Can't open PID file /run/nginx.pid (yet?) after start"
To fix it, you need to change the owner of the file /run/nginx.pid from root to nginx I execute

the command chown -R nginx:nginx /run /nginx.pid
Owner changed, but reverts back to root file owner after nginx reload.
What to do?

Answer 1

Came across this mess. One thing is written in the config, another is written in the system unit. Somehow it needs to be more consistent. See what you have on your system /run or /var/run . There you need to fix the file.

Answer 2

I think /run/nginx.pid is a symlink. Change (or delete) the file where it points
