nginx pid directive and reload doesnot work in openresty

[项楠]

user  root;

pid   /tmp/nginx.pid;

worker_processes  1;

error_log  logs/error.log  error;

events {

    worker_connections  1024;

}

http {

    default_type  "text/html; charset=UTF-8";

    server {

        listen       8080;

        server_name  localhost;

        location / {

            root   html;

        }

    }

}

I install openresty in the default path. my project path is `/root/op`, and I start with 

nginx -p `pwd`/ -c conf/nginx.conf

But 

1. openresty still create pid file in `/root/op/logs/`

2. when you try `nginx -s reload`, it fails with 

nginx: [error] open() "/usr/local/openresty/nginx/logs/nginx.pid" failed (2: No such file or directory)

so question is:

1.how to specify location of pid file?

2.how to reload nginx?

Because you started your nginx with the -p option, then you should
still use that exactly the same -p option when calling nginx with
-sreload.

BTW, do not use nginx -sreload to reload nginx unless you are on
Windows. Always send the HUP signal to your nginx master process
directly. The -s option has unwanted side-effects that may surprise
you (like loading the nginx configuration one more time).
