MagicMirror-Install-Guide-Raspberry-0-to-3

Rather than an install script a guide on how easy it is to install NodeJS and magic mirror works for all Pi and also includes 0 scripts which don’t use the incompatible electron Armv7l package

Grab you image from raspberrypi.org/downloads/raspbian/

Its up to you which you use but as in the name Raspbian Raspbian Stretch Lite Latest is the lightest and likely to create the best results.
For a mirror that will generally be remote and a mirror installing a full desktop is likely pointless.

Flash the image using Etcher from https://www.balena.io/etcher/
Boot and then enter your WiFi details as the presumption is you will have a WiFi mirror.

So our flash is complete and we are going to boot our pi zero and create some settings. All we need is the SSID of your WiFi router (The name it lists up as when you connect) My ssid=“TALKTALKF20CC3” My psk=“VE3JAX5F” (MyWifi password)

So we are going to login: login: = pi password = raspberry
then type: sudo raspi-config and press enter
Choose 2: Network Choose N2: WiFi Select your country. Enter your ssid. Enter your wifi password.
Choose 5: Interfaces Choose P2: SSH Yes to enable.
Tab to finish and Yes to reboot

We need a SSH client such as Putty or Bitvise.
Also Notepad++ is a great little editor that supports Unix & Windows LF/EOF formats.
If your unsure the sugestions is Bitvise & Notepad++

When the Pi reboots in the boot console log on screen you should now see a line My IP address is … copy that into the Server Host address and the pi/raspberry login details and login.

Update your system and install the base packages for MagicMirror

sudo apt-get update -y
sudo apt-get upgrade -y
sudo apt-get dist-upgrade -y

Pi0/1 owners yeap the first boot update/upgrade to get the latest will be a :sleeping: experience with Pi 2/3 owners being slightly less :sleeping:.
So now we have a completely updated and upgraded Pi and now to install Mirror specific packages.

sudo apt-get install -y chromium-browser unclutter lightdm git rpd-plym-splash plymouth-x11 xdotool

NodeJS for Pi 0/1 Armv6l is supported but not pakaged due to problems with Chromium compile for electron, this is no problem as the NodeJS NVM NodeVersionManager is excellent and probably should be used for all Pi versions.
If you have a Pi 2/3 armv7l processor then you can install NodeJS via raspbian packages sudo-apt-get instal… but the NVM gives far better control.
Read the GitHub ReadMe for a run down of how to use NVM and what it is capable of.
To install

curl -o- https://raw.githubusercontent.com/creationix/nvm/v0.34.0/install.sh | bash

As it will tell you close the current SSH console or reboot. So do so and install Node with…

nvm install --lts

As we will use the latest Long Term Support Version.

##Cloning & Installing MagicMirror
From the MagicMirror site click on repository and copy the url or click the green clone button and copy from there.

git clone https://github.com/MichMich/MagicMirror.git

Then we will enter the MagicMirror folder and start the install

cd ~/MagicMirror && npm install

More :sleeping: time.
So that MagicMirror will autostart and restart on failure we are going to install the NodeJS Process Manager PM2 and if you need further infomation the documentation is great.
So to install

npm install pm2@latest -g

Then we are going to ask PM2 for the correct startup command and paste that into the console.

pm2 startup

Which for me returns, but trust PM2 and not me.

[PM2] To setup the Startup Script, copy/paste the following command:
sudo env PATH=$PATH:/home/pi/.nvm/versions/node/v10.15.1/bin /home/pi/.nvm/versions/node/v10.15.1/lib/node_modules/pm2/bin/pm2 startup systemd -u pi --hp /home/pi

So do as said and copy & paste what PM2 tells you.
This is where us Pi0/1 and 2/3 owners depart as the need of use of Chromium rather Electron dicates some small changes.
For Pi 0/1 owners.
For Pi 2/3 owners the last thing is.

pm2 start ~/MagicMirror/installers/pm2_MagicMirror.json

Save that for autoboot

pm2 save

Copy the sample config.js to the config folder

wget https://raw.githubusercontent.com/StuartIanNaylor/MagicMirror-Install-Guide-Raspberry-0-to-3/master/config.js -O ~/MagicMirror/config/config.js

And we are ready to go with

DISPLAY=:0 npm start

Thats it unless you wish to read Make things Plymouth pretty and Save my Flash in the above to folders on instructions how to have a MagicMirror splash screen and how to use zram and tools to limit flash writes to a minimium. Apart the last bit about raspi-config and desktop autologin.

So back to Pi0/1 users.
The quickest and easiest way is to create a ~/.Xsession file and here is a sample config.

nano ~/.Xsession

Paste the following

xset s off
xset -dpms
xset s noblank
sleep 20
chromium-browser --noerrdialogs --kiosk http://localhost:8080 --incognito --disable-translate --window-size=1920,1080 --window-position=0,0

Then edit run-start.sh

sed -i 's/electron js\/electron.js /node serveronly /g' ~/MagicMirror/run-start.sh

So it looks like

if [ -z "$DISPLAY" ]; then #If not set DISPLAY is SSH remote or tty
	export DISPLAY=:0 # Set by default display
fi
node serveronly $1

So for Desktop Autologin

sudo raspi-config

3 Boot options
Desktop/CLI
Desktop Autologin

Then like the P2/3 owners add and save to PM2

pm2 start ~/MagicMirror/installers/pm2_MagicMirror.json

Save that for autoboot

pm2 save

Then reboot

pm2 save

Great job! I ve got it to work - it runs fine on my Pi0!
Thank you for your great efforts.

What you can do is add a script line to run-start-sh

Call it xdotool.sh
so you would have sh xdotool.sh

after

if [ -z "$DISPLAY" ]; then #If not set DISPLAY is SSH remote or tty
	export DISPLAY=:0 # Set by default display
	
fi
sh xdotool.sh &
node serveronly $1
xdotool.sh

xdotool.sh contains

export DISPLAY=:0
sleep 25
xdotool search --onlyvisible --class "chromium" key ctrl+F5

The above will make Chromium refresh on any config.js changes or any restart of the server.

If have been banging my head against a brick xorg / plymouth combination for no reason than to get a smooth splash screen all the way till the browser displays.
This seems far more trouble than its worth.
I included lightdm as thought that might make things easier but might drop it as it seems to make no difference and just adds bloat.

https://www.semicomplete.com/projects/xdotool/ is excellent for external control just haven’t spent much time with it yet with my plymouth waste of time.

@ stuartiannaylor

That sounds like exacly what I’m looking for :thumbs_up:

I finished my first MagicMirror and looking for tuning options.
As exp. I would like to small the case a bit and would be happy to use Rpi0 instead of Rpi3.

I followed your instruction “MagicMirror-Install-Guide-Raspberry-0-to-3”

I installed a new raspbian “Raspbian Buster with desktop”
may this cause my issues not using “Raspbian Buster Lite”?

I run in problem with command

cd ~/MagicMirror/ && npm install

as I got many WARN and ERR messages. I’m not alowed to attach because the file type is .log so I will paste only the WARN and ERR instead of the whole log-file.

Any idea :nerd_face: what to do getting the RasPi0 run?
Hold in mind what happen in case of newer MagicMirror software or other updates need to run automaticly.

Many thanks, bdream

sdetweil

@bdream try my updated installer, I am working to get this to replace the current version…

see https://forum.magicmirror.builders/topic/10171/anyone-want-to-try-updated-installer
others have reported it works ok on Pi zero

rename the MagicMirror folder or remove it before running the installer

bdream

ok, many thanks! :grinning_face: I will try it now.
Just deleted the MagicMirror folder…

If I understand you correctly the new script will replace the old one as:

~~curl -o- https://raw.githubusercontent.com/creationix/nvm/v0.34.0/install.sh | bash~~

bash -c "$(curl -sL https://www.dropbox.com/s/rlh710ng0zwv3vp/raspberry.sh?dl=0)"

but all other in your manual will stay. Right?

CU, bdream

sdetweil

@bdream the installer also fixes pm2 and the screen saver
and creates a log of the install process results

i don’t think u will need the other steps in the pi0 manual anymore

bdream

thanks for this info, so I know what to do if my attempt to fix first installation only by deleting /MagicMirror and start your script fails :frowning_face: :winking_face:. And it failed :frowning_face:

I get a new “Raspbian Buster Lite” now and start again :nerd_face:

Will let you know about the outcome. It will take long time :sleeping_face:

Best gerads, bdream

sdetweil

@bdream said in YAPi0 Installer Stretch Lite:

start your script fails . And it failed

please post the contents of ~/install.log

bdream

Ohh sdetweil, my bad. I overwrote the SD-card already with the new image. I have to learn how to work with forum and being sensitive for upcoming questions/requests.

For now I started your script again an it seems it’s running :sleeping_face:

I wonder as I have on screen a warning
