OSX - Start and Stopping of Nginx error

Question

I install nginx via home brew and when i try to start or stop it i get the following error

➜  ~  sudo nginx -s stop
nginx: [error] open() "/usr/local/var/run/nginx.pid" failed (2: No such file or directory)
➜  ~  sudo nginx
nginx: [emerg] bind() to 0.0.0.0:8080 failed (48: Address already in use)
nginx: [emerg] bind() to 0.0.0.0:8080 failed (48: Address already in use)
nginx: [emerg] bind() to 0.0.0.0:8080 failed (48: Address already in use)
nginx: [emerg] bind() to 0.0.0.0:8080 failed (48: Address already in use)
nginx: [emerg] bind() to 0.0.0.0:8080 failed (48: Address already in use)
nginx: [emerg] still could not bind()

File structure

➜  ~  /usr/local/var/run
➜  run git:(master) ls
nginx
➜  run git:(master) cd nginx
➜  nginx git:(master) ls
client_body_temp fastcgi_temp     proxy_temp       scgi_temp        uwsgi_temp
➜  nginx git:(master)

To check if nginx is running

➜  ~  ps waux | grep nginx
harshamv          963   0.0  0.0  2432772    656 s000  S+    1:32PM   0:00.00 grep --color=auto --exclude-dir=.bzr --exclude-dir=.cvs --exclude-dir=.git --exclude-dir=.hg --exclude-dir=.svn nginx

When i try to run Nginx i get the following error.

➜  ~  nginx
nginx: [alert] could not open error log file: open() "/usr/local/var/log/nginx/error.log" failed (13: Permission denied)
2015/07/02 13:39:44 [emerg] 1074#0: open() "/usr/local/var/log/nginx/access.log" failed (13: Permission denied)

There is one case I have met. If you start nginx with a conf file, which looks like nginx -c my.conf, you have to stop it with nginx -s stop -c my.conf.

In your my.conf file, you may use pid /some_location/nginx.pid;, and this will generate a pid file at that location, which is not any more the default location at /usr/local/var/run/nginx.pid, and this is why you cannot stop it.

I think when you met such error, you have an option to check ps -ef | grep nginx for its pid, at least can kill it manually.
