Let’s deploy a project using Mina.
Your server needs to be properly configured for mina to work. Requirements for mina 1.0 to work:
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, 'your.server.com'
set :deploy_to, '/var/www/flipstack.com'
...
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. (http://rbenv.org)
# require 'mina/rvm' # for rvm support. (http://rvm.io)
...
...
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'
end
...
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.
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.
If you changed shared_files and shared_dirs in your deploy.rb you have to run mina setup again. This ensures all needed folders are created.
