Thanks Sam

Huh. I just tried it on a fresh Buster install on a RPI 3B+ and PM2 failed to install correctly. It seems to be a permissions issue.

@bhepler show me the log please

~/install.log

bhepler

It’s not terribly illuminating.

install and setup pm2
pm2 not installed, installing
pm2 install result
get the pm2 platform specific startup command
startup command =
pm2 startup command done
configure the pm2 config file for MagicMirror
start MagicMirror via pm2 now
save MagicMirror pm2 config now
disable screensaver via lxsession

sdetweil

@bhepler hang on, I’ll be back home in a few minutes.

Can u do

pm2 startup

bhepler

@sdetweil I already went through the installation procedure to get pm2 installed. That required the npm command to install pm2.

After the initial script run, pm2 start MagicMirror returned a “bash: pm2: command not found” error. Once I got pm2 installed, getting the script monitored by pm2 was easy enough. At a guess, it’s a problem with using sudo to install pm2, but I’m afraid I don’t have the exact error message.

sdetweil

@bhepler what did u have to do for the pm2 install?

bhepler

@sdetweil - I pulled this from the official GitHub page: sudo npm install -g pm2. Once I ran that, I just changed to the ~/MagicMirrors/installers folder and told pm2 to run/maintain it: pm2 start mm.sh

sdetweil

@bhepler weird… that is that the script does between the two log entries

	echo pm2 not installed, installing >>$logfile	
	result=$(npm install $up -g pm2)
	echo pm2 install result $result >>$logfile

$up is for the mac

bet it needed sudo…

sdetweil

@bhepler

I also added to catch the stderr output to the log too

	echo pm2 not installed, installing >>$logfile	
	result=$(sudo npm install $up -g pm2 2>&1)
	echo pm2 install result $result >>$logfile

sdetweil

@bhepler could you retest the installer? just rename your current MagicMirror folder out of the way… thanks

course u have pm2 already … never mind

bhepler

@sdetweil - No worries. I have a spare Pi and a SD card I can use. I’ll get it cranked out tonight. I’ll get you that info.

sdetweil

@bhepler thanks… i got some new sd cards today, so I will test too.

bhepler

@sdetweil - Brand new Buster installation on a RPi 3B+. Installation script worked as expected.

I had trouble with pm2 on my existing mirror too. I ended up upgrading to the latest pm2 in order to get it to remember to start on boot.

At this point, I think your script is handling it properly. Thanks for the quick replies!

sdetweil

@bhepler oh, there is a script for just pm2 as well.

Thx for feedback.

Hey sam (@sdetweil ),

Thanks for this, made my life a lot easier.

So, I just did a new build with Buster on a RPI Zero W. All looked good and I have configured mm2 to start on reboot of the Pi. I am start/stop/restart and check the status of mm2 and is looks to be working, the mm2 logs are also good with no error logs.

The problem I am facing is that the magicMirror page via chromium seems to try and load (white screen which changes to a pure black screen) however seems to fail/crash and go back to the Raspbian desktop.

This happens when I reboot the pi and also when I manually try to start/restart the mm2 service.

Anything you think I am missing?

Thanks

sdetweil

@NathTheDude if u start the chromium browser from the desktop does it work?

sdetweil

U may need to increase the swap space. Pi 0 has very little memory.

NathTheDude

Thanks @sdetweil , after a couple of reboots this is now working as expected. Not sure what the issue was, I will have to keep an eye on it. Thanks for the link on swap space, I will also look in that direction if I have any more of the same issues.

sdetweil

@NathTheDude ok… let me know if there are any other issues…
