Install nginx

複製底下的 output

which passenger-install-nginx-module

然後把 output 用 rvmsudo 執行

rvmsudo OUTPUT

# Choose "download, compile, and install Nginx for me"
# Accept defaults for any other questions it asks you

setup a script to control Nginx

sudo git clone git://github.com/jnstq/rails-nginx-passenger-ubuntu.git
sudo mv rails-nginx-passenger-ubuntu/nginx/nginx /etc/init.d/nginx
sudo chown root:root /etc/init.d/nginx
sudo /etc/init.d/nginx restart

set up nginx.conf

vim /opt/nginx/conf/nginx.conf

insert following codes into the /opt/nginx/conf/nginx.conf

server {
      listen 80;
      server_name my_project.cc;
      root /home/apps/my_project/current/public;
      passenger_enabled on;
      rails_env production;
    }

create folder for the project

cd ~
mkdir ~/my_project

set production database.yml and secrets.yml

cd ~
mkdir ~/my_project/shared
mkdir ~/my_project/shared/config

加入database.yml

vim /home/apps/my_project/shared/config/database.yml

production:
  adapter: my_project_use_adapter
  encoding: utf8
  reconnect: false
  database: my_project_database
  pool: 5
  username: username
  password: password

加入secrets.yml

vim /home/apps/my_project/shared/config/secrets.yml

production:
  secret_key_base: <%= ENV["SECRET_KEY_BASE"] %>

set up deploy key for apps

ssh-keygen
more ~/.ssh/id_rsa.pub
複製！！

Add the SSH key to GitHub

https://help.github.com/articles/generating-ssh-keys

Set up authorized keys for developers

vim /home/apps/.ssh/authorized_keys

Paste the ssh public keys into the "/home/apps/.ssh/authorized_keys" file

（複製本機的id_rsa.pub貼在server的authorized_keys檔案內）

Set up Capistrano

Add the following Gems to your Gemfile

gem 'capistrano', '3.1.0'
gem 'capistrano-rails', '~> 1.1.0'
gem 'capistrano-bundler'
gem 'capistrano-rvm'

run

bundle install
bundle exec cap install

Paste following codes into the "/my_project/Capfile" file

# Load DSL and Setup Up Stages
require 'capistrano/setup'

# Includes default deployment tasks
require 'capistrano/deploy'

# Includes tasks from other gems included in your Gemfile
#
# For documentation on these, see for example:
#
#   https://github.com/capistrano/rvm
#   https://github.com/capistrano/rbenv
#   https://github.com/capistrano/chruby
#   https://github.com/capistrano/bundler
#   https://github.com/capistrano/rails
#
require 'capistrano/rvm'
require 'capistrano/rails'
require 'capistrano/bundler'
#require 'capistrano/rbenv'
#require 'capistrano/chruby'
#require 'capistrano/rails/assets'
#require 'capistrano/rails/migrations'

# Loads custom tasks from `lib/capistrano/tasks' if you have any defined.
Dir.glob('lib/capistrano/tasks/*.cap').each { |r| import r }

Paste following codes into the "/my_project/config/deploy.rb" file

# Ensure that bundle is used for rake tasks
SSHKit.config.command_map[:rake] = "bundle exec rake"

set :application, 'my_project'
set :scm, :git
set :repo_url, '[email protected]:yourself/my_project.git'
set :deploy_via, :remote_cache
set :stages, ["production"]
set :deploy_to, '/home/apps/my_project'

# how many old releases do we want to keep
set :keep_releases, 5

# files we want symlinking to specific entries in shared.
set :linked_files, %w{config/database.yml config/secrets.yml}


namespace :deploy do

  # make sure we're deploying what we think we're deploying

  desc 'Restart application'
  task :restart do
    on roles(:app), in: :sequence, wait: 5 do
      # Your restart mechanism here, for example:
      # execute :touch, release_path.join('tmp/restart.txt')
    end
  end

  after :publishing, :restart

  after :restart, :clear_cache do
    on roles(:web), in: :groups, limit: 3, wait: 10 do
      # Here we can do anything such as:
      # within release_path do
      #   execute :rake, 'cache:clear'
      # end
    end
  end

  after :finishing, 'deploy:cleanup'

end

Paste following codes into the "/my_project/deploy/production.rb" file
(請自行修改使用ssh_key登入或是使用password登入,官方建議使用ssh_key,設定方式為上面的_Set up authorized keys for developers_)

server "your_production_ip", user: 'apps', roles: %w{app web db},
       ssh_options: {
           user: 'apps', # overrides user setting above
           keys: %w(/home/user_name/.ssh/id_rsa),
           forward_agent: false,
           auth_methods: %w(publickey password),
           #password: 'password'
       }
