Problems with starting pm2 start mm.sh

madoXX

Hi,

i made everything link written in this tutorial
https://github.com/MichMich/MagicMirror/wiki/Auto-Starting-MagicMirror
but i stack here:

"
Starting your MagicMirror with PM2
Simply start your mirror with the following command:
pm2 start mm.sh
You mirror should now boot up and appear on your screen after a few seconds.
"

It doesn’t

when i enter pm2 start mm.sh i receive the following message:

[PM2] Starting /home/pi/mm.sh in fork_mode (1 instance)
[PM2] Done.
┌──────┬────┬──────┬────────┬───┬─────┬──────────┐

└──────┴────┴──────┴────────┴───┴─────┴──────────┘
Use pm2 show <id|name> to get more details about an app

thats it.

When i reboot i see the Magic Mirror Screen but the Raspi starts always the standard desktop.

Any suggestions?

Thank you very much!

Did you also follow this point:

Starting PM2 on boat
To make sure PM2 can do it’s job when (re) booting your operating system, it needs to be started on boot. Luckily, PM2 has a handy helper for this.

pm2 startup
PM2 wants to show you a command you need to execute.

Thanks for your reply. For the moment i want to know why it doesn’t even start, when i try to start it manually.

Moreover, here the content of the file mm.sh (saved in /home/pi)

cd ~/MagicMirror
DISPLAY=:0 npm start

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

cd ~/MagicMirror

change that 1st line to be

cd /home/pi/MagicMirror

pm2 is running under root at the time of startup

ok, seems pm2 is not setup right

1st make sure script works
is it executable?
chmod +x mm.sh

/home/pi/mm.sh &
(and stop it)
then 

pm2 remove 0
pm2 startup
   this will return a command u need to execute (cut/paste)
pm2 start /home/pi/mm.sh
pm2 save

then

pm2 list

nothing running

pm2 start mm

should start ok

reboot

Thanks anyway for your help!

@madoXX does it restart on boot?

pm2 remove 0
should have been
pm2 delete 0

and yep, needed a stop after the pm2 save
