client让我远程 帮他把项目部署到服务器上。什么都没给，只好自己想办法，边查资料边部署。
首先把代码给搞下来。
[yzhang@localhost ~]$ mkdir trust
[yzhang@localhost ~]$ cd trust
[yzhang@localhost trust]$ svn checkout http://........
用户名：
密码：
[yzhang@localhost trust]$ cd trunk
[yzhang@localhost trunk]$ ls
app config doc lib public README sendmails.rb tmp
components db document log Rakefile script test vendor
[yzhang@localhost trunk]$ vi config/database.yml

从命令行模式转到末行模式用 “：”，然后用wq保存修改并推出。

[yzhang@localhost trunk]$ vi config/database.yml
[yzhang@localhost trunk]$ pwd
查看当前目录路径
/home/yzhang/trust/trunk
[yzhang@localhost trunk]$ mongrel_rails cluster::configure -e development -p 8090 -N 4 -c /home/yzhang/trust/trunk -a 127.0.0.1
Writing configuration file to config/mongrel_cluster.yml.
[yzhang@localhost trunk]$ mongrel_rails cluster::start
starting port 8090
starting port 8091
starting port 8092
starting port 8093
[yzhang@localhost trunk]$ pwd
/home/yzhang/trust/trunk
[yzhang@localhost trunk]$ mysql -u wwsr_user -p
