# BDSM Rails Extension
2+
3+
The Rails extension is used to manage all aspects of a Ruby/Rails
4+
application project deployment as a user.
5+
6+
For example, if the project name is 'todo' then for deployment
7+
you would typically create an 'todo' user on the server with
8+
home directory of /home/todo.
9+
10+
An example walkthrough of using BDSM Rails extension in conjunction
11+
with other extensions (below) to manage an application deployment.
12+
13+
root# bdsm install rails deploy unicorn nginx
14+
15+
todo$ bdsm bdsmrc
16+
todo$ vim ~/.bdsmrc # Adjust any settings necessary, set repo url.
17+
todo$ bdsm rails setup
18+
todo$ vim ~/shared/config/database.yml # Tune your database.
19+
todo$ bdsm deploy # Deploy the applicatoin using the 'deploy' ext.
20+
todo$ cd ~/current
21+
todo$ gem install bundler && bundle install # If you swing that way.
22+
todo$ bdsm unicorn install
23+
todo$ bdsm rails console
24+
todo$ bdsm unicorn start # If console loaded properly, start er up!
25+
26+
root# bdsm nginx install
27+
root# bdsm nginx server todo
