2571	"Start non-blocking error when using the ""user"" setting"	Mathieu REHO		"Having this as SystemD override configuration :

{{{
# cat /etc/systemd/system/nginx.service.d/override.conf 
[Service]

PIDFile=/run/nginx/nginx.pid

RuntimeDirectory=nginx
RuntimeDirectoryMode=0775

LimitNOFILE=1048576
}}}

and this as the begining of my nginx.conf :


{{{
# cat /etc/nginx/nginx.conf 
user					nginx www-data;
...
}}}

I get this error in my main Nginx error log :

{{{
2023/12/03 17:55:05 [warn] 624580#624580: the ""user"" directive makes sense only if the master process runs with super-user privileges, ignored in /etc/nginx/nginx.conf:1
2023/12/03 17:55:05 [emerg] 624580#624580: open() ""/run/nginx/nginx.pid"" failed (13: Permission denied)
}}}

While I do not user the User nor Group directive inside the Nginx's SystemD service configuration.. so nginx master process runs as root before downgrading, so the error has no sense.

For information :

{{{
# ls -la /run/nginx
total 2
drwxrwxr-x  2 root root  100 Dec  3 17:55 .
drwxr-xr-x 45 root root 1380 Dec  3 17:55 ..
-rw-r--r--  1 root root    7 Dec  3 17:55 nginx.pid
}}}
