Posted byOnur Güzel	7 September 2012	22 Comments on Supervisord: Restarting and Reloading
Supervisord is a great daemon for managing application processes. However it does not have a reload option, and restart works different than we get used to. These command makes the following effects.

service supervisor restart
Restart supervisor service without making configuration changes available. It stops, and re-starts all managed applications.

supervisorctl restart <name>
Restart application without making configuration changes available. It stops, and re-starts the application.
