Moving the OctoPrint installation directory

Get Help
1

I followed the instructions to set up OctoPrint on my Raspberry Pi running Raspbian. It's running nicely and starts on boot.

However, I would like to move the installation directory from ~/OctoPrint to ~/bin/OctoPrint to keep my home directory organized. When I move the directory, OctoPrint will no longer run:

~/bin/OctoPrint/venv/bin $ ./octoprint
-bash: ./octoprint: /home/keavon/OctoPrint/venv/bin/python2: bad interpreter: No such file or directory

Can I please have a complete list of steps needed to update my installation for its life in a new location?

It's relatively simple. Due the link, change the fourth line to:

mkdir OctoPrint && cd OctoPrint -> mkdir bin/OctoPrint && cd bin/OctoPrint

If you would be sure to make all changes has effect, rename origin folder:

OctoPrint -> OctoPrint.old

and

.octoprint -> .octoprint.old

too.
So you have a chance to step back if something would be wrong and be sure the new position is running. Don't forget to modify the configuration file (if you are automtically running the OctoPrint server) in:

/etc/default/octoprint

if you are running Armbian...

Good luck

Hello, thanks for the reply. I am a bit confused reading what you wrote, but it looks like you are suggesting that I rename the old directory and then follow the steps again to reinstall the program? Is there a simpler way to just move my existing installation?

Oh, I am very sorry. Yes you are right, you have to repeat the installation process againg due the link above with your changes in creating new path.
I don't know if exist simpler process to move Octoprint to new location, but I am affraid not because during the installation the actual paths are builded-in into installation (I think).

The reason the OctoPi image was created was so that a dedicated $35 computer could be used to serve this up. In my humble opinion, "organizing the home directory" isn't required and only serves to break a perfectly working collection of activities.

I am not using OctoPi, I am installing OctoPrint on my regular Raspberry Pi that I use for many other purposes. That would be a pretty bad design if the software requires such a nonportable installation environment, do you know if that is actually the case, and the reason for the errors printed in my above reply that show up after performing the installation instructions elsewhere from the home directory?

On the plus side, OctoPrint is open source so feel free to search through the github repository to determine what's required to change it to suit your needs.
