 Replace the old Nginx binary (by default, /usr/local/nginx/sbin/nginx) with the new one.

 Find the pid of the Nginx master process, for example, with ps x | grep nginx | grep master or by looking at the value found in the pid file.

 Send a USR2 (12) signal to the master process kill USR2 ***, replacing *** with the pid found in step 2. This will initiate the upgrade by renaming the old .pid file and running the new binary.

 Send a WINCH (28) signal to the old master process kill WINCH ***, replacing *** with the pid found in step 2. This will engage a graceful shutdown of the old worker processes.

 Make sure that all the old worker processes are terminated, and then send a QUIT signal to the old master process kill QUIT ***, replacing *** with the pid found in step 2.
