1.操作系统 centos5.4
2.安装ruby
yum install ruby
会安装得到 1.8.5
如果你公司用的是1.8.X就无所谓了，
拿这个学习就行了
如果你们公司用的是1.9.X，那么你需要去下载源码进行安装。【你会很悲剧的发现下载已被伟大祖国的万里长城封锁了】
我这里使用1.8.5学习就ok了
3.安装rails
yum -y install rubygem-rails.noarch
4.看看安装完毕的成果
[root@localhost projects]# ruby -v
ruby 1.8.5 (2006-08-25) [x86_64-linux]
[root@localhost projects]# rails -v
Rails 2.1.1
5.建立rails档案
mkdir projects
cd projects
rails new demo
圣经说：
如果出現建立出來的目錄不是demo而是new，表示你的Rails版本是舊版的，請輸入rails -v檢查Rails的版本必須是3.0以上。不是的話，請回上一章末執行gem install rails安裝Rails 3
老版本就老版本吧
不管他
6.启动服务器 ./script/server
[root@localhost new]# ./script/server
=> Booting WEBrick...
=> Rails 2.1.1 application started on http://0.0.0.0:3000
=> Ctrl-C to shutdown server; call with --help for options
