之前做的Python小站点均是用nginx反代方式，实际使用python app.py方式启动，显着是非常不专业啊。而且效率也没测试过。

真正对Python感兴趣时候是从[observer专栏杂记]的 使用python爬虫抓站的一些技巧总结等文章开始的。So，之前因为部署uwsgi太麻烦虽然收藏了observer的配置Nginx＋uwsgi更方便地部署python应用文章，但一直没有实际去配置过。

为了表示不停折腾精神，这几天把网址缩短项目用bottle重写一下（bottle只有一个文件，比tornado轻量多了，反正俺也无需考虑效率问题），部署在一个亚马逊免费的EC2(Elastic Compute Cloud)上。此次修改Todo list还包含引入免费的redis（使用redis4you提供的免费5M服务）等。

所以趁此从头开始的机会，配置了一下uwsgi。记录下完整安装过程（其中好多安装配置copy自lnmp.org的centos.sh中配置）。

申请亚马逊免费EC2的教程不提供了，自己Google一下，网上有详细的图文教程的。

    return "Hello world!"
if __name__ == "__main__":
    # Interactive mode
    run()
else:
    # Mod WSGI launch
