Python – Supervisord: Can supervisord monitor remote processes

pythonsupervisord

Can supervisord be used to start remote processes, monitor and manage the processes?

Best Answer

I'm not an expert, but I doubt it - the Features list says:

You can configure Supervisor to provide a local or remote command line and web interface.

Which means you can certainly control supervisord remotely, but there must be a copy of supervisord on the same machine as the controlled processes.

Supervisor HTTP Server Port Issue

Just ran into this as well. I fixed it by doing either of these:

sudo unlink /tmp/supervisor.sock

sudo unlink /var/run/supervisor.sock

This .sock file is defined in /etc/supervisord.conf [unix_http_server] file config value (default is /tmp/supervisor.sock or /var/run/supervisor.sock).

Hope this helps someone in the future.

Django, uWSGI and Supervisord config

I found this was pretty confusing until I discovered emperor mode.

This means you can do one supervisord instance to manage all of your configs:

[program:uwsgi]
command=/usr/local/bin/uwsgi --emperor /etc/uwsgi/apps-enabled
stopsignal=QUIT
autostart=true
autorestart=true
redirect_stderr=true

And then you'd pop any config files (ini, xml, yaml) for apps into the /etc/uwsgi/apps-enabled directory.

Not sure if this works with 0.9, but defintely works with 1.0.

Here's an example ini for a Flask app:

[uwsgi]
socket = /tmp/uwsgi_%n.sock
module = wire:app
chdir = /srv/%n/wire
env = WIRE_SETTINGS=/srv/%n/wire/config.py
virtualenv = /srv/%n
uid = wire
gid = www-data
single-interpreter = false
chmod = 770
processes = 3
