服务器

帐户用ROOT最方便，装sshd git

chmod 600 /root/.ssh/id_rsa

本地

capify .

部署脚本

vi config/deploy.rb

default_run_options[:pty] = true

set :user, "root"
set :use_sudo, false
set :group_writable, false

set :application, "hululuu.com"
set :deploy_to, "/srv/http/#{application}"
set :repository, "[email protected]:takafan/hululuu.git"
set :scm, :git

@domain = domain rescue nil
set :domain, application unless @domain

role :web, domain                   # Your HTTP server, Apache/etc
role :app, domain                   # This may be the same as your `Web` server
role :db,  domain, :primary => true # This is where Rails migrations will run
role :db,  domain

第一次生成目录结构

cap deploy:setup

部署

cap deploy

unicorn配置脚本

vi config/unicorn.rb

app = 'hululuu.com'
app_path = "/srv/http/#{app}/current"
user = 'root', 'root'
worker_processes 1

working_directory app_path

listen "/tmp/#{app}.sock", backlog: 2048

timeout 30

pid_file = "/tmp/#{app}.pid"
pid pid_file

preload_app true

before_fork do |server, worker|
  old_pid = pid_file + '.oldbin'
  if File.exists?(old_pid) && server.pid != old_pid
    begin
      Process.kill("QUIT", File.read(old_pid).to_i)
    rescue Errno::ENOENT, Errno::ESRCH
    end
  end
end
