Ref:http://learnaholic.me/2012/10/10/installing-nginx-in-mac-os-x-mountain-lion/

3. Start nginx
bash$ ngix
Chrome localhost:8080

4. Stop nginx
$nginx -s stop

4. Re-Start nginx

==> Pouring nginx-1.8.1.yosemite.bottle.tar.gz

==> Caveats

Docroot is: /usr/local/var/www

The default port has been set in /usr/local/etc/nginx/nginx.conf to 8080 so that

nginx can run without sudo.

nginx will load all files in /usr/local/etc/nginx/servers/.

To have launchd start nginx at login:

  ln -sfv /usr/local/opt/nginx/*.plist ~/Library/LaunchAgents

Then to load nginx now:

  launchctl load ~/Library/LaunchAgents/homebrew.mxcl.nginx.plist

Or, if you don't want/need launchctl, you can just run:

  nginx
