Running more printers on the same Pi

[guysoft]

OctoPi can support multiple instances of OctoPrint. There should be a simple way to create new instances.

Currently the workaround is to simply put another instance of OctoPrint on startup using this command:

~/oprint/bin/python ~/OctoPrint/run --daemon start --port 5001 --pid /tmp/octoprint2 --basedir ~/.octoprint2

There is also a talk about this in OctoPrint: OctoPrint/OctoPrint#113 (comment)

I know this thread is over two years old now but I'm thinking about doing just this and have a question. If you create a second OctoPrint Instance how do you connect to it? Do you jsut go to http://octopi.local:5001 to access the second instance?

[guysoft]

@LieutenantHawkeye Yes, that should do it.
But I am not sure the "restart OctoPrint" in the system menu would work, because all that is set up to work on the main instance,

[humford]

@guysoft BTW do you just type that command into the terminal for the pi? Sorry I'm a newb at this kind of thing

[guysoft]

Yes, that would be a good start to see that it works. Youncan then look in to how to make it start on boot.

know this is old but how would I make this command start at boot, right now I just replaced the restart octoprint command in octoprint settings with the one here so I can start it quickly without SSH but I would like some recomendation on how to go about enabling this command to autoluach at boot. Thanks!

General advice for running commands on boot in linux is add the commands to /etc/rc.local but no guarantee this is the best option for whatever you are trying to do here

You need to create a systemd service.

/etc/systemd/system/rc-local.service

[Unit]
Description=/etc/rc.local Compatibility

[Service]
Type=oneshot
ExecStart=/etc/rc.local
TimeoutSec=0
StandardInput=tty
RemainAfterExit=yes

[Install]
WantedBy=multi-user.target

They new RaspberryPi 4 might actually revive this talk.

Is this issue still relevant ? Because you could leverage systemd template units (ie octoprint@.service, with the port as the instace "name", and a corresponding script to prepare for another configuration directory).
I'd be willing to work on a PR to get it done.
