PM2 restart won’t work.
Could you have a look, please.
Thanks a lot

@kurt looks like there is currently no instance running that can be restarted so just start a new one by doing pm2 start mm

Thank you, this is what I get…

@kurt [PM2][ERROR] script not found

did you follow these steps to create the script? https://github.com/MichMich/MagicMirror/wiki/Auto-Starting-MagicMirror

kurt

@strawberry-3.141
yes I did it following the steps in that wiki

Shouldn’t pm2 start mm be executed in ~ and not in ~/MagicMirror ? The tutorial said to create mm.sh in ~

So please go back one folder with cd .. or directly with cd ~ and try again

kurt

@yawns
this is what I get,
do you think it is a good idea to start the install routine once again from the beginning? pi@raspberrypi:~ $
in my modules folder there is no PM2 folder. Should there be one?
Thanks a lot for help

If you want to start the process with npm start then you have to do that inside ~/MagicMirror
However if you want to use pm2 then I would advise following the instructions again: https://github.com/MichMich/MagicMirror/wiki/Auto-Starting-MagicMirror

pm2 seems to be working fine on your raspberry, so I would start here:

Make a MagicMirror start script. To use PM2 in combination with MagicMirror, we need to make a simple shell script. Preferable, we put this script outside the MagicMirror folder to make sure it won’t give us any issues if we want to upgrade the mirror.

cd ~
nano mm.sh

Add the following lines:

cd ~/MagicMirror
DISPLAY=:0 npm start

Save and close, using the commands CTRL-O and CTRL-X. Now make sure the shell script is executable bij performing the following command:

chmod +x mm.sh

You are now ready to the MagicMirror using this script using PM2.

@yawns
my first step was to make this start script following the instructions.
the mm.sh with the script cd ~/MagicMirror DISPLAY=:0 npm start is now in my /home/pi folder.
When I try to start the mm by npm start I get this (the mirror is not appearing):

Thank you

EADDRINUSE means, there is another process running and listening on port 8080
It looks like the magicmirror somehow is running already.
