git服务部署及capistrano部署完整教程20101220
生成远程git仓库
mlzboy@mlzboy:~$ mkdir -p git/b2c2.git
mlzboy@mlzboy:~$ cd git/b2c2.git/
mlzboy@mlzboy:~/git/b2c2.git$ git init --bare
Initialized empty Git repository in /home/mlzboy/git/b2c2.git/
生成ssh公钥
将生产服务器上的公钥,放到远程git仓库所在的服务器上
ssh-keygen -t rsa
一路回车
进入到cd ~/.ssh目录下
mlzboy@mlzboy-MacBook ~/.ssh $ ls
authorized_keys id_rsa id_rsa.pub known_hosts
mlzboy@mlzboy-MacBook ~/.ssh $
将id_rsa.pub命名为authorized_keys上传到git仓库所在服务器的 ~/.ssh下
如果没有该目录,则可以使用ssh-keygen -t rsa创建
将本地库添加远程仓库
mlzboy@mlzboy-MacBook ~/my/b2c2 $ git remote add vm mlzboy@192.168.1.103:/home/mlzboy/git/b2c2.git
mlzboy@mlzboy-MacBook ~/my/b2c2 $ git push vm master
使用git remote -v查看当前库所有的远程仓库

使用cap deploy:setup构建初始结构
在shared下创建config文件夹,将config下的database.yml和smtp_gmail.yml放到该config下
将public下system文件夹放到对应的shared/system中
执行cap deploy
注意要启动nginx,目录ubuntu下没有设为开机自动启动nginx
注意cap deploy:migrate执行的生产环境,所以建议还是上服务器上去使用rake db:migrate去执行

#使用capistrano-helper还可以改进,不过使用这个gem目前还有依赖问题,有待研究

nginx+passenger在实际部署时遇到,即使sudo kill pid也没办法删除假死的passenger,只有重启服务器,不知道该如何解决
如果想在capistrano中集中migrate功能,为保险起见一定要先执行完整备份mysql的操作,以免意外情况发生
