Nginx still try to open default error log file even though I set nginx config file while reloading

The below is my nginx configuration file located in /etc/nginx/nginx.conf

user Foo;worker_processes 1;error_log /home/Foo/log/nginx/error.log;pid /home/Foo/run/nginx.pid;events {    worker_connections 1024;    use epoll;}http {    access_log /home/Foo/log/nginx/access.log;    server {        listen 80;        location = / {            proxy_pass http://192.168.0.16:9999;        }    }}

As you can see I change log, pid files location into home directory.

When I re-start Linux it seems to work, Nginx records error logs in the file I set and pid file also.

However, when it tries nginx -s reload or the other, It tries to open other error log file.

nginx: [alert] could not open error log file: open() "/var/log/nginx/error.log" failed (13: Permission denied)2015/12/14 11:23:54 [warn] 3356#0: the "user" directive makes sense only if the master process runs with super-user privileges, ignored in /etc/nginx/nginx.conf:1nginx: the configuration file /etc/nginx/nginx.conf syntax is ok2015/12/14 11:23:54 [emerg] 3356#0: open() "/home/Foo/run/nginx.pid" failed (13: Permission denied)nginx: configuration file /etc/nginx/nginx.conf test failed

I know, I can solve permission error with sudo but the main issue in here is a error log file(/var/log/nginx/error.log) Nginx tries to open.

Why does it try to access another error log file?
