Updating to a new nginx binary on the fly Edit

This is described on the official wiki at:

Basically it boils down to the following:

Get PID of old master process by inspecting output of ps:

$ ps auxwww | grep nginx

(You could also just cat /var/run/nginx.pid.)

Now, install the new binary:

$ sudo make install

Advise old master process to start a new master process using the updated binary:

$ sudo kill -s USR2 2941

Gracefully shut down old worker processes:

$ sudo kill -s WINCH 2941

Gracefully exit old master process:

$ sudo kill -s QUIT 2941

See the official wiki for more info on how to do other things like backing out of an update.
