SFW RaspberryPi

Smallest Federated Wiki on hosted on a Raspberry pi

This example is used on a default Raspberry-pi installation (Wheezy).

The installation of SFW with node.js can take several hours on the Raspberry-pi. You can copy/paste the following codes one by one and have a functional SFW setup when finshed.

Make sure you can access the Rpi over ssh ... if you need to enable ssh you can run the config with:

sudo raspi-config

(find the ssh entry in the list and enable)

Connect to your Rpi on another pc in a terminal with ssh (you need to know the ip of the Rpi):

ssh pi@your_local_ip 

example:

ssh [email protected]

(default password is "raspberry")

Once you have access with ssh you should be able to paste the following code's in the terminal one by one and end with a functional SFW hosted on the Raspberry Pi. (on linux copy with: Ctrl-c and paste in the terminal with Ctrl-Shift-v)

Start here:

cd /

Install node.js

sudo apt-get install python g++ make

create a folder for node

mkdir ~/nodejs && cd $_

get a known working version of node currently (Apr 2013) the limiting factor is substack/bouncy

wget -N http://nodejs.org/dist/v0.8.23/node-v0.8.23.tar.gz

unpack

tar xzvf node-v0.8.23.tar.gz && cd node-v0.8.23

configure

./configure

make (this step takes about 2.5 hours ...)

sudo make install

...check if node is installed properly by checking the version:

node -v

SFW is distributed as a GitHub repository ... so we need to install git

sudo apt-get install git

(follow the instructions and confirm on installation with a "y")

We make a directory to install the SFW node app

sudo mkdir  /opt/apps

adjust the rights

sudo chmod -R 775 /opt/apps/

make the user a member ("pi" the user)

chown ${USER}:pi -R /opt/apps/

cd in the folder

cd opt/apps

Get the SFW repo with git

git clone https://github.com/WardCunningham/Smallest-Federated-Wiki.git

cd to server/express

cd Smallest-Federated-Wiki/server/express

install with npm

npm install

go to bin

cd bin

Start SFW

node server.js

Visit SFW in a browser on another pc with the local ip you use for the Raspberry pi and add the default port :3000

example:

192.168.1.68:3000

In the terminal you can stop SFW again by typing Ctrl-C
