1. vim Gemfile, 增加:

gem 'capistrano'

2. $ bundle install

3. $ capify .
会生成两个文件: Capfile ,  config/deploy.rb

4. 编辑后者,然后 $ cap deploy.

5. $ cap deploy:setup 会建立必须的 文件夹

6. 编辑 $ shared/config/database.yml

7. 加入下面几行:

  1 load 'deploy/assets'
  2 set :rake,      "bundle exec rake"
32 namespace :assets do
33   task :precompile do
34     run "cd #{release_path} && bundle exec rake RAILS_ENV=production RAILS_GROUPS=a
35   end
36 end
37
38 desc "Copy database.yml to release_path"
39   task :cp_database_yml do
40     puts "executing my customized command: "
41     puts "cp -r #{shared_path}/config/* #{release_path}/config/"
42     run "cp -r #{shared_path}/config/* #{release_path}/config/"
43   end
44
45 before "deploy:assets:symlink", :cp_database_yml
46
