Clean uninstall?

[DrTron]

All,
I've been playing around with genmon and came to the conclusion that I need to install it on a different machine.
It's running fine, but is there a good way to cleanly uninstall genmon (including the dependent python modules)?

For some reason "startgenmon.sh stop" doesn't even stop genmon, it keeps running...

Thanks!

Hi @DrTron

the startgenmon.sh stop command will only work if genmon was started with the startgenmon.sh script.

The uninstall depends on your python environment. If you are using a managed python environment the you can just delete the genmon folder and the /etc/genmon folder, then remove the entry in cron that starts genmon on boot. You can tell if you have a managed python environment if it was installed on bookwork or if you have a folder named genenv in the ./genmon directory. The genenv folder contains the python virtual environment so deleting that takes care of the python libraries.

from your user folder:

restore the serial port settings:

 python ./genmon/OtherApps/serialconfig.py -r

then delete the genmon files:

  sudo rm -r ./genmon

then delete the config files:

  sudo rm -r /etc/genmon

To remove the cont tab, edit the cron file

  sudo contab -e

then remove the that looks like this:

 @reboot sleep 30 && /bin/bash /home/pi/genmon/startgenmon.sh start

then save the file (Ctrl+X, y, Enter for nano editor)

Note the path could be different if your user directory is not "pi"

Once the entry in crontab is gone you can reboot and genmon should not be loaded.

If you are not in a manage python environment, before remove the genmon folder, type this command to uninstall all the python libraries (note that if you have installed other software uninstalling some libraries cause dependancies problems with your python environment):

  sudo pip3 uninstall -r ./genmon/requirements.txt -y

This step just frees up and disk space, so if your system is running ok there is an argument for not performing this step to avoid dependency problems.

Thanks!
It actually was started via the startgenmon.sh bash script, so I was a bit surprised.
But good to know the installation didn't spread beyond the install directory and /etc/genmon.

I discovered too late that the wifi module in my generator is "closed up" with no way to access it. Would have been too easy.
Now I have to consider whether I will place a Pi out at the generator like everyone else seems to do and connect it via serial port. From what I read, the generator probably has one somewhere.
