how to define start order in group of processes using supervisord?

问题

Does the program priority determine the start order? i.e. baz then bar ?

If I have:

[group:foo]
programs=bar,baz

And:

[program:bar]
command=/path/to/bar
priority=200

As well as:

[program:baz]
command=/path/to/baz
priority=150

Yes. Lower priorities indicate programs that start first and shut down last at startup and when aggregate commands are used in various clients (e.g. “start all”/”stop all”). Higher priorities indicate programs that start last and shut down first.
