Setting up a project

Let’s deploy a project using Mina.

Step 0: Configure server

Your server needs to be properly configured for mina to work. Requirements for mina 1.0 to work:

Step 1: Create a config/deploy.rb

In your project, type mina init to create a sample of this file.

$ mina init
Created config/deploy.rb.

This is just a Rake file with tasks! See How to write your own tasks for more info on what deploy.rb is. You will want to at least configure your server:

# config/deploy.rb
set :user, 'username'
set :domain, ''
set :deploy_to, '/var/www/'

Notes: You may be using a ruby versioning tool (rbenv or RVM) to manage ruby and gems. If you are using one of them, don’t forget to uncomment these settings:

require 'mina/bundler'
require 'mina/rails'
require 'mina/git'
# require 'mina/rbenv'  # for rbenv support. (
# require 'mina/rvm'    # for rvm support. (
task :environment do
  # If you're using rbenv, use this to load the rbenv environment.
  # Be sure to commit your .ruby-version or .rbenv-version to your repository.
  # invoke :'rbenv:load'

  # For those using RVM, use this to load an RVM version@gemset.
  # invoke :'rvm:use', 'ruby-1.9.3-p125@default'

Step 2: Run ‘mina setup’

Back at your computer, do mina setup to set up the folder structure in deploy_to path. This will connect to your server via SSH and create the right directories.

$ mina setup
-----> Creating folders... done.

See directory structure for more info.

Step 3: Deploy!

Use mina deploy to run the deploy task defined in config/deploy.rb.

$ mina deploy
-----> Deploying to 2012-06-12-040248
       Lots of things happening...
-----> Done.
