Description
My nginx is installed from nginx official yum repo. However, when I started nginx by the command:
systemctl start nginx
, it failed with timeout. See the error message:
systemctl status nginx Jan 15 11:05:07 dsrl2.dsrl systemd[1]: PID file /run/nginx.pid not readable (yet?) after start. Jan 15 11:07:06 dsrl2.dsrl systemd[1]: nginx.service start operation timed out. Terminating. Jan 15 11:07:06 dsrl2.dsrl systemd[1]: Failed to start nginx - high performance web server. Jan 15 11:07:06 dsrl2.dsrl systemd[1]: Unit nginx.service entered failed state. Jan 15 11:07:06 dsrl2.dsrl systemd[1]: nginx.service failed.
I find the PID file path in /lib/systemd/system/nginx.service is different form /etc/nginx/nginx.conf. After I modify the path in nginx.conf, systemctl successfully starts nginx. Please fix this inconsistent PID file paths problem.

Replying to i.bakirov@…:
Ticket 1069 said the issue is harmless. But, it is harmful on my CentOS 7, because I find /var/run is not a symbolic link to /run in my CentOS 7. With the inconsistent PID paths, systemd start nginx will be timeout and then nginx process will be killed.
Additionally, I don't very understand the issue in 884 ...

That's weird. Can you show the output of the following commands:
# rpm -q filesystem
# rpm -V filesystem
# mount | grep run
# ls -la /run/
# ls -la /var/run/
?

Interesting. It seems something went really wrong when installing your OS, because filesystem package creates /run and symlinks /var/run into it:
I would guess with such a broken install you will encounter many more issues than just nginx, so I'd advise you to fix your OS, instead of introducing /var/run/nginx.pid to nginx.service (which contradicts current CentOS/RHEL guidelines: https://access.redhat.com/documentation/en-US/Red_Hat_Enterprise_Linux/7/html/Migration_Planning_Guide/sect-Red_Hat_Enterprise_Linux-Migration_Planning_Guide-File_System_Layout.html)

Thanks for your information. I think of that I didn't install CentOS by ISO on my this PC, but by a tar of another PC, which installed CentOS by ISO.

Actually, this is the first time I encounter the /var/run symlink issue...
I have no answer whether the inconsistent paths of the nginx rpm should be made consistent or not. Nevertheless, my nginx now works.

I've made the paths consistent in the packaging sources; will be available on the next nginx releases (1.12.1 and 1.13.2).
