关键字: capistrano
1，客户端机器安装Capistrano 
gem install -y capistrano


2，应用到项目 
cd D:\projects\beyondrails
capify .


3，修改config\deploy.rb 
DEPLOY_PATH = "/var/www/vhosts/hideto/html/www.beyondrails.com"

set :application, "beyondrails"
set :repository, "https://beyondrails.googlecode.com/svn/trunk/beyondrails"
set :scm_username, "hideto.bj"
set :scm_password, "######"

set :deploy_to, DEPLOY_PATH
set :user, "hideto"
set :password, "######"
ssh_options[:port] = 2048

role :app, "120.72.34.135"
role :web, "120.72.34.135"
role :db,  "hideto", :primary => true


desc "Restart the web server for www.beyondrails.com"
task :restart, :roles => :app do
  run "cd ~;./restart-www.beyondrails.com.sh"
  quit
end

desc "Stop the web server for www.beyondrails.com"
task :stop, :roles => :app do
  run "cd ~;./stop-www.beyondrails.com.sh"
end

desc "Update and restart web server for www.beyondrails.com"
task :update_and_restart, :roles => :app do
  run "cd #{DEPLOY_PATH};svn up"
  run "cd #{DEPLOY_PATH};rake db:migrate"

cap update_and_restart
cap stop
cap restart

需要注意的是必须在一条run命令中执行cd到某一目录，可能cap的实现就是一条run命令执行一次ssh连接，所以放在多条run命令下的话上下文就无法保持了
