How to restart nginx on OS X

Question

I\'m using nginx on OS X 10.8. Freshly installed nginx but can\'t find a way to restart nginx except kill nginx_pid say kill 64116

Answer 1

To reload config files:

sudo nginx -s reload

To fully restart nginx:

sudo nginx -s quit
sudo nginx

Details

There is no restart signal for nginx. From the docs, here are the signals that the master process accepts:

SIGINT, SIGTERM  Shut down quickly.
SIGHUP           Reload configuration, start the new worker process with a new configuration, and gracefully shut down old worker processes.
SIGQUIT          Shut down gracefully.
SIGUSR1          Reopen log files.
SIGUSR2          Upgrade the nginx executable on the fly.
SIGWINCH         Shut down worker processes gracefully.

Presumably you could send these signals to the process id manually, but the nginx command has the flag nginx -s that sends signals to the master process for you. Your options are:

stop    SIGTERM
quit    SIGQUIT
reopen  SIGUSR1
reload  SIGHUP

No need to futz with the pid manually.
