Problems restarting MagicMirror (Port 8080 in use ...)

[MichMich]

@cowboysdude Ah, so you’re experiencing the same? In that case it’s worth diving into …

[PindaPower]

@MichMich I’m not running the develop branch, but I do know the background off the feedback (port 8080 is use). I’m not sure if your looking for this information, other ways let me know.

Same for me, if you mean this Messages (I’m using the main 2.1):

MagicMirror will not quit, but it might be a good idea to check why this happened. Maybe no internet connection?
If you think this really is an issue, please open an issue on GitHub: https://github.com/MichMich/MagicMirror/issues

Ups, there a bug for pm2 config. I pushed a fix
https://github.com/MichMich/MagicMirror/pull/640

The restart is work for me. Are you try stop/start?

pi@raspberrypi:~/MagicMirror $ pm2 status MagicMirror

By the way, there a interesting notice in restart process by pm2

Restarts are now immutable, to update environment or conf use --update-env

Here I’m using 2.1.5 version

pi@raspberrypi:~/MagicMirror $ pm2 -version
2.1.5

@roramirez said in Problems restarting MagicMirror (Port 8080 in use ...):

pi@raspberrypi:~/MagicMirror $ pm2 -version
2.1.5

Do I need pm2?

pi@MagicMirror:~ $ pm2 -version
-bash: pm2: Kommando nicht gefunden.

(translates: command not found)

[ostfilinchen]

@roramirez what i have to do to get the fix from github? I have installed MM v2.1.0

[MichMich]

This seem to have fixed the issue. Thanks @roramirez!

Do I need pm2?

Is optional. If you installed by script and choice. After that you can configurate mannually.

[roramirez]

@ostfilinchen That version don’t have the feature for use pm2 for process control by installer script. What is your problem in 2.1.0?

[ostfilinchen]

@roramirez my Problem is this error

when i restart the mirror via pm2

[cowboysdude]

Thanks guys!

[roramirez]

@ostfilinchen What pm2 version are using?. There are other process to start control of MagicMirror?

Please, send some log lines of pm2 and what show you
pm2 status

[ostfilinchen]

@roramirez i think the Problem is the pm2. My in Memory Version is 2.0.19 and my local Version is 2.3.0.

if i do pm2 update it updates the Version, but if i restart the pi, i have 2 Versions again.

[roramirez]

@ostfilinchen So stranger. What is for you memory version?

Note: The last stable release of pm2 is 2.2.1.

I recomend use the last version stable. In my case, the 2.1.5, work fine the restart action.

[ostfilinchen]

@roramirez thanks for the Information. how can i update to 2.1.5?

[roramirez]

@ostfilinchen by npm

sudo npm install -g pm2@2.1.5

First remove previous version installed
https://docs.npmjs.com/cli/uninstall

[ostfilinchen]

@roramirez i’ve done this and have a look on the restartprocess in the next time. thanks a lot.
