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

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…

after a few reboots now everything is starting fine.
A big thanks to the community here!
Very helpfull people here!

Gomalley

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

Detto65

@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

sdetweil

@Detto65 yes, the install script uses a json file to configure the pm2 process

Gomalley

When i do

pm2 list

The "name, id, mode, status, cpu, and memory chart shows up. It is all in blue.
Below it, it says “use ‘pm2 show <id/name>~ to get more details about an app.’”

When i type in

pm2 start

The same chart above displays along with a message saying
[PM2] [ERROR] File ecosystem.config.js is not found

What does this mean?

Raksasas

I am having the same problem: I did what was mentioned above and after the reboot it stll did not start automaticly. Running “pm2 list” after the reboot shows mm.sh is not runnning.

@Raksasas should be executing those while in the MagicMirror folder

Raksasas

@sdetweil

Looking over the “Auto Start” page I do not see where it states that the pm2 commands are to be run while inside the MagicMirror folder.

With you stating that it seems to be saying that the “mm.sh” script needs to be ran from inside the “MagicMirror” too. Again the “Auto Start” page shows that it was created inside the ‘home’ (~) folder. So one would think/presume it can be ran from inside the “home” folder also.

Either way I will give it a go.
