I can't get supervisord to work; after starting the process with:

# supervisord -n -c /etc/supervisord.conf
2013-05-29 11:34:11,861 CRIT Supervisor running as root (no user in config file)
2013-05-29 11:34:11,868 INFO supervisord started with pid 7893

From another terminal, I get:

# supervisorctl -c supervisord.conf status
error: <class 'socket.error'>, [Errno 2] No such file or directory: file: <string> line: 1

Running in vagrant, CentOS 6.3 x86_64.

supervisor.rpcinterface_factory = supervisor.rpcinterface:make_main_rpcinterface

serverurl=unix:///var/run/supervisor.sock ; use a unix:// URL  for a unix socket

Trying to find the socket file:

# ls /var/run/supervisor.sock
ls: cannot access /var/run/supervisor.sock: No such file or directory

  • I have the same problem. Maybe you somehow manage to fix it? Please share :) – egis Jun 30 '13 at 20:42
  • Yes, the problem was too old a version, I fixed up a puppet repo. – Henrik Jul 1 '13 at 6:14
  • FYI, the actual error error: <class 'socket.error'>, [Errno 2] No such file or directory: file: <string> line: 1 just means that supervisor is not running and supervisord cannot connect to it, hence the socket error. – A. McB Sep 15 '15 at 22:34

The problem was that the version was old and buggy:

I have upgraded this: https://github.com/haf/puppet-supervisor to install the latest version of supervisor.

The core problem seems to be that failure to launch the daemon the first time creates the socket file at the run location, but the initv script doesn't support removing it (so it must be done manually).


I had the same problem. The cause was running supervisord version 2.x instead of 3.x. Upgrading supervisord solved the problem.
