@madoXX does it restart on boot?

pm2 remove 0
should have been
pm2 delete 0

and yep, needed a stop after the pm2 save

no, the boot menu from the magic mirror appears (booting up), no error but it goes straight to the desktop.

something strang here

@sdetweil said in Problems with starting pm2 start mm.sh:

then
pm2 list

nothing running

In fact the themm.sh is running caus i startet it above

@sdetweil said in Problems with starting pm2 start mm.sh:

pm2 start /home/pi/mm.sh

madoXX

OK command back…

A big thanks to the community here!
Very helpfull people here!

I’m actually having thus EXACT problem and it is very frusterating. Im having a little trouble reading all of the instructions to fix it. Did you get yours fixed? If so exactly what did you do to fix it?

sdetweil

@Gomalley pm2 runs a script,
installers/mm.sh

It should read

cd /home/pi/MagicMirror
...etc

Change it if not.

Then

pm2 restart 0

Gomalley

I tried it but I do not think that it worked. My code before I touched it read

cd ~/MagicMirror

Now i tried two things both gave same output

cd ~/home/pi/MagicMirror

and

cd /home/pi/MagicMirror

It now says
[PM2] Spawning PM2 daemon with pm2_home=/home/pi/.pm2
[PM2] PM2 Successfully daemonized
Use --update-env to update environment variables
[PM2] Applying action restartProcessId on app [0](ids: [ ‘0’ ])
[PM2] [ERROR] Process 0 not found

In my mm.sh the file currently reads this:
cd /home/pi/MagicMirror
DISPLAY=:0 npm start

Gomalley

And I tried restarting the pi and the “Booting up” MagicMirror2 showed but it never actually loaded.

sdetweil

@Gomalley ok

pm2 list

If nothing

pm2 start installers/mm.sh
pm2 save

@madoXX
just did a fresh install of my magicmirror, because the sd card went corrupt.
during the install procedure it somehwere asked me if i want to autostart MagicMirror.
after that it started automatically after booting into the desktop first.
When trying to use pm2, it shows me the process is already running, but it’s name is MagicMirror , not mm.
MagicMirror version 2.8.0
