The Raspberry PI is a really inexpensive little computer. It has an ARM
processor, 512 MB of RAM and it runs Linux. I use it to host my website
at home. It's a perfect fit for Octopress.
In this article I explain, how you I set it up. I assume that its pretty
simple for everyone using Octopress of course ;)
First download Raspbian. It's a variant of Debian, that is optimized for
the Raspberry Pi.
And then transfer it onto a SD-Card.
sudo dd bs=1m if=2012-12-16-wheezy-raspbian.img of=/dev/rdisk2
Now put the SD-Card into your Raspberry Pi and boot.
Afterwards you should change some defaults in the configuration tool for
sudo reboot now
Now is the time to use your bigger computer and SSH into your
Look up the ip for eth0. In my case it's 192.168.2.102. Another possibility is to use the Web Interface of your router. Usually you should see the IP there as well.
Now log into your pi.
We need a webserver, so lets install one.
sudo aptitude install apache2
Check if it works - enter the IP of your Raspberry Pi into your
Webbrowser. You should see It Works.
Octopress uses rsync in order to deploy its files. You can install it with:
sudo aptitude install rsync
Now its time to configure octopress.
cd octopress vim Rakefile
Change the Rsync options to:
## -- Rsync Deploy config -- ssh_user = "pi@THE_IP_OF_YOUR_RASPBERRY_PI" ssh_port = "22" document_root = "/var/www/" rsync_delete = false rsync_args = "" # Any extra arguments to pass to rsync deploy_default = "rsync"
Copy your public key into your clipboard. If you do not have one yet, you have to generate a key-pair.
Your key should be stored in ~/.ssh and end with a .pub
Copy it into your clipboard.
Then add it to your Raspberry Pi
cd ~ mkdir .ssh nano ~/.ssh/authorized_keys
Paste your key and save. Then adjust the permissions.
chmod 600 .ssh/authorized_keys
We're nearly done now. The webserver runs. You should be able to login
into you Raspberry Pi without a password and rsync is ready to go. So
cd octopress bundle exec rake gen_deploy
Now reload the browser again.
Tada! You're done. You should see your website on the RaspberryPi now.
