Python Web 部署是 uWSGI 还是 gunicorn 更优？

不知道....不会 [Python]

vi ~/.pip/pip.conf
[global]
index-url = http://pypi.tuna.tsinghua.edu.cn/simple
# 或者
http://pypi.douban.com/simple  豆瓣

# 安装 lxml ，依赖啊依赖
$sudo apt-get install libxml2-dev libxslt-dev python2.7-dev
$sudo pip install lxml

Gunicorn 看起来很简单直观，uWSGI 还没研究过。。

不过就算用 Gunicorn，也要有个 nginx 搭配。

@onlyice Gunicorn 实际上启动的是 python 自己的 Http 服务？而 WSGI 是另外的基于 socket 的协议

使用测试服务器

看来是 uwsgi 最快

@zonghua 难以一两句话说清楚，可以参考下我之前写的帖子：

测试很棒

@onlyice 网络的话除了 Http 的东西我都看不懂了
