Recommended way to start supervisord from non-root bash script

rootsupervisord

I have set up supervisor to monitor some processes. Because I deploy via remote script, I need a way to send supervisor start/stop commands without sudo. I'm not sure how to do this though.

Is there a way in supervisor to run specified commands as a non root user?

The supervisorctl command can be run as a non-root user. All you need to do is give it permission to connect to the supervisord process.

You'll need to configure access in the appropriate server section, so in the [unix_http_server] section, or in the [inet_http_server] section, whichever you are using for your supervisord setup.

If you use the [unix_http_server] setup, you'd add chmod and/or chown directives to control who can access the UNIX domain socket, for example:

[unix_http_server]
chown = youruser

so that youruser can write to that socket, which means supervisorctl can send supervisord commands. You can also add a group:

[unix_http_server]
chown = youruser:yourgroup

Finally, you'll have to restart supervisord itself with service supervisor restart

Try commenting out this param. If you don't specify a user, it should run with the same user id that started the process.

user=jason ; default user

Have you tried using sudo somecommand instead of trying to switch users? Your user will need to be in the 'wheel' user group (depending on your system) to do that.

su changes the environment (user variables etc.) so, though I haven't tested this, you probably can't do it in a shell script.

Example:
Your shell script was

#Do these commands as a normal user
echo "Hello World"
cat ./somefile

#Do these commands as root
su -
echo "Hello again"
cat /etc/somesystemfile

try changing it to

#Do these commands as a normal user
echo "Hello World"
cat ./somefile

#Do these commands as root
sudo echo "Hello again"
sudo cat /etc/somesystemfile
