Problems with starting pm2 start mm.sh

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

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

@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

sdetweil

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

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?

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.

@Raksasas My mm.sh resides in my /pi/ folder and not in the MagicMirror folder so should work. It might be that there was an error while you were setting up pm2 or setting up the autostart perhaps?

sdetweil

@Raksasas it was the

pm2 start installers/mm.sh

That needed to be done from the MagicMirror folder.

Cause I ‘ASSUMED’ if u were working on mm, you would always be in that folder.

installers folder is in mm, not in user home

Raksasas

Part 1:
@sdetweil

Just tried the

pm2 start installers/mm.sh
pm2 save

From within the “MagicMirror” folder and no change. MagicMirror starts and at reboot it does not automaticly start

See below for my fix

Part 2:
@mumblebaj
This seems possible. So i re-ran

sudo npm install -g pm2
pm2 startup

After running “pm2 startup” this time I noticed the following:

To setup the Startup Script, copy/paste the following command:
sudo env PATH=$PATH:/usr/bin /usr/lib/node_modules/pm2/bin/pm2 startup systemd -u pi --hp /home/pi

So I ran that and followed with the “pm2 start mm.sh” and “pm2 save”. Well now it is auto starting on reboot.

@Raksasas great news!

mumblebaj

@Raksasas Exellent. Great it is working now.
