把GAE程序通过SSH部署到VPS

大部分在文档上都写了, 写这篇文章的目的是发现现在appcfg.py update xxxx的时候会打开浏览器访问google请求授权(后台内建了一个本地server, 端口是8090, 授权成功后会带授权码请求本地的8090端口, 所以我们在 ssh 环境中是没有浏览器的, 该怎么解决呢?

我玩 linux 不多, 就以我的知识量这么解决:

1. 碰到需要访问网站的时候, 程序已经给出了提示, 要你退出, 你当然不退出, 而是把网址复制出来, 在本地打开, 授权成功后, 本地浏览器会请求127.0.0.1:8090, 当然, 什么都不会发生, 但从地址栏里把地址复制到剪贴板.
2. 回到SSH, 把当前任务放到后台(ctrl+z)
3. 用curl访问剪贴板里的地址
4. 继续ctrl+z把curl请求放到后台
5. jobs命令查一下, 如果后台没有别的任务的话, appcfg任务的id 应该是1, curl任务id 应该是2(现在以我的1和2为准)
6. 把appcfg提到前台: fg %1
7. 你会看到程序顺利进行下去了
8. 继续, fg %2把 curl 任务提到前台, 你会看到提示, 什么授权成功之类的
