3. How?
Don't reinvent the wheel,
use existing tools:

• git
• sinatra

4. nginx/passenger configuration
>sudo gem install passenger
>sudo passenger-install-nginx-module
server {
listen 80;
server_name bivouac.com www.bivouac.com;
root /home/bivouac/current/public;
passenger_enabled on;
}
server {
listen 80;
server_name *.bivouac.com;
root /home/bivouac/apps/$host/public;
passenger_enabled on;
}

5. git
• how we get our code on the server
• hooks for restarting the site
Look in .git/hooks/ for samples
We use the post-receive hook

6. The Sinatra App
• one model – Sites
• name:string
• ssh_public_key:string

7. on Site creation
• create folder in webserver dir
• git init .
• create git post-receive hook
• add key to authorized_keys
• show git commands

8. post-receive hook
cd #{site.directory} && git --git-dir=`pwd`/.git reset –hard;
# Matches the working tree and index to that
of the tree being switched to (defaults to HEAD).
touch #{site.directory}/tmp/restart.txt
# tells passenger to restart the site
