关于服务器——安装配置tornado

tornado是另一个基于python的服务器框架，虽然不能向django一样给我们提供丰富的“建站工具”，不过它对epoll的支持使得非阻塞特性比较吸引人。下面也简单记录一下安装使用方法。

首先下载安装tornado，运行它还需要安装下面两个库

1，pycurl

2，mysql-python?

?（python setup.py install）

?

tornado没有提供django的manage.py，django-admin.py等工具，直接编码如下

list_publishers.html（模板）

?简单用ab测试一下性能，要比django性能高出一倍的样子（不过鉴于两个项目操作数据库的方式有些不一样，还是没有说服力，原因在于没能找到tornado对sqlite的原生支持）

?简单的配置，就让我们可以远离老掉牙的php-cgi编程了。
