Answer 1

Yes, you can.

nginx -s reload

Or you can send SIGHUP to the nginx process.

sudo kill -HUP [nginx pid]

Answer 2

You can load a new configuration using signals . Will be

1. Read and test the new configuration. If the configuration is incorrect, then do nothing.
2. When this is true, start working with new workers with a new configuration. Connect new workers to port listening, registration, etc.
3. Disconnect old workers from students.
4. Gracefully shut down the old workers.

You can even upgrade to a new binary on the fly. See the same document.

To reboot, send a reload signal:

 nginx -s reload
