I wanted to get node.js and mongoDB up and running on my pi. I’ve got a couple of pet projects which I’m going to tackle and I’ve decided to use the MEAN stack (MongoDB, Express, AngularJS and Node.js). The future, for now, is JavaScript and I’m looking to know enough to make informed decisions about my place in that future.
These are the steps that I followed to get it going …
First up, node.js …

Before doing this step you want to check what the latest version is – go to http://nodejs.org/dist/ and browse, starting from the biggest number backwards, looking for a release that includes “linux-arm-pi” in the title. That’s the one to use in the following code snippet, for me it was v0.10.24/node-v0.10.24-linux-arm-pi.tar.gz
sudo mkdir /opt /node
wget http : //nodejs .org /dist /v0 . 10.24 /node -v0 . 10.24 -linux -arm -pi .tar .gz
tar xvzf node -v0 . 10.24 -linux -arm -pi .tar .gz
sudo cp -r node -v0 . 10.24 -linux -arm -pi /* /opt /node
sudo nano /etc /profile
add the following before “export PATH ”
NODE_JS_HOME ="/opt/node"
PATH ="$PATH:$NODE_JS_HOME/bin"
That’s it! Next let’s get a server running so we can make sure it’s working … create the following content in a file called nodejs.sh

#!/bin/bash
NODE =/opt /node /bin /node
SERVER_JS_FILE =/home /pi /app /server .js
USER =pi
OUT =/home /pi /nodejs .log
case "$1" in
start )
echo "starting node: $NODE $SERVER_JS_FILE"
sudo -u $ USER $ NODE $ SERVER_JS_FILE > $ OUT 2 > $ OUT &
; ;
stop )
killall $ NODE
; ;
*)
echo "usage: $0 (start|stop)"
esac
exit 0
then do the following to get it to run on pi boot
chmod 755 nodejs .sh
sudo cp nodejs .sh /etc /init .d
sudo update -rc .d nodejs .sh defaults
now for the server.js that will run our server
mkdir /home /pi /app
cd /home /pi /app
nano server .js
put the following in the server.js file
var http = require ( 'http' ) ;
http . createServer ( function ( req , resp ) {
resp . writeHead ( 200 , { "Content-Type" : "text/plain" } ) ;
resp . write ( "Hello World" ) ;
resp . end ( ) ;
console . log ( "sample output to console" ) ;
} ) . listen ( 8080 ) ;
then start the server
sudo /etc /init .d /nodejs .sh start
A quick visit to http://192.168.0.123:8080 should result in a nice “Hello World” message.
Finally a bit of tidying up in /home/pi/
rm nodejs .sh
rm -rf node -v0 . 10.24 -linux -arm -pi
rm node -v0 . 10.24 -linux -arm -pi .tar .gz
Next up – mongoDB
https://github.com/RickP/mongopi and http://ni-c.github.io/heimcontrol.js/get-started.html
Note, the scons commands performs the build and will take a few hours each
sudo apt -get install git -core build -essential scons libpcre ++-dev xulrunner -dev libboost -dev libboost -program -options -dev libboost -thread -dev libboost -filesystem -dev
git clone git : //github .com /RickP /mongopi .git
cd mongopi
scons
sudo scons --prefix =/opt /mongo install
scons -c
sudo nano /etc /environment
add this before “export PATH ”
PATH =$ PATH : /opt /mongo /bin /
Then set up a new db and configure it to start on boot:
sudo useradd mongodb
sudo mkdir /var /lib /mongodb
sudo chown mongodb : mongodb /var /lib /mongodb
sudo mkdir /etc /mongodb /
sudo sh -c 'echo "dbpath=/var/lib/mongodb" > /etc/mongodb/mongodb.conf'
cd /etc /init .d
sudo wget -O mongodb https : //gist .github .com /ni -c /fd4df404bda6e87fb718 /raw /36d45897cd943fbd6d071c096eb4b71b37d0fcbb /mongodb .sh
sudo chmod +x mongodb
sudo update -rc .d mongodb defaults
sudo service mongodb start
You can test everything went ok by launching the MongoDB shell with the command “mongo” … see the docs for more info.
Job Done!
