之前一直使用Nginx+Fastcgi來搭建python web服務器，本文介紹Nginx+UWSGI組合來實現。uWSGI 是一個快速的、純C語言開發的、自維護的、對開發者友好的WSGI服務器，旨在提供專業的 Python web應用發布和開發。它更符合python web的標準協議，速度要比Fastcgi要快、性能更加穩定。

一、安裝平臺
1、安裝pcre

2、安裝Nginx

3、安裝python&Mysql-python

4、安裝MySql-python

5、安裝Django

6、安裝uWSGI

二、平臺配置

1、平臺環境說明
  1.1、項目位置：/opt/www/Purgesys
   創建項目方法：

  1.2、查看項目(出現以下文件結構說明項目已創建成功)
  #tree Purgesys

2、Nginx相關配置

#cd /usr/local/nginx/conf
#vi django_uwsgi.conf

# Django projectserver {        listen  80;        server_name purgesys.domain.com;        location / {            uwsgi_pass   127.0.0.1:9000;            include     uwsgi_params;            access_log  off;        }        location ^~ /static {                root   /opt/www/Purgesys;        }        location ^~ /admin/ {            uwsgi_pass   127.0.0.1:9000;            include  uwsgi_params;            access_log   off;        }        location ~* ^.+/.(mpg|avi|mp3|swf|zip|tgz|gz|rar|bz2|doc|xls|exe|ppt|txt|tar|mid|midi|wav|rtf|mpeg)$ {            root   /opt/www/Purgesys/static;            access_log   off;        }}

*Nginx-0.8.50默認已添加uwsgi輸出頭支持
include uwsgi_params;

#vi nginx.conf
追加子配置文件django_uwsgi.conf

http{ ........ include django_uwsgi.conf; } 

3、UWSGI配置
#mkdir -p /home/uwsgi;cd /home/uwsgi
#mkdir -p /opt/www/logs
#echo "" > /opt/www/logs/django.log
#vi uwsgi.xml

<uwsgi> <socket>127.0.0.1:9000</socket> <listen>200</listen> <master>true</master> <pidfile>/usr/local/nginx/uwsgi.pid</pidfile> <processes>8</processes> <pythonpath>/opt/www/Purgesys</pythonpath> <pythonpath>/opt/www/</pythonpath> <module>django_wsgi</module> <profiler>true</profiler> <memory-report>true</memory-report> <enable-threads>true</enable-threads> <logdate>true</logdate> <limit-as>6048</limit-as> <daemonize>/opt/www/logs/django.log</daemonize></uwsgi>

4、創建應用模塊
cd /opt/www/Purgesys
vi django_wsgi.py

import osos.environ['DJANGO_SETTINGS_MODULE'] = 'Purgesys.settings'import django.core.handlers.wsgiapplication = django.core.handlers.wsgi.WSGIHandler()

5、啟動服務
#/usr/bin/uwsgi -x /home/uwsgi/uwsgi.xml
#/usr/local/nginx/sbin/nginx

6、查看進程
#[liuts@webserver nginx]# ps -ef|grep uwsgi|grep -v grep

7、監聽端口
#[liuts@webserver nginx]# netstat -an|grep 9000
引用

tcp 0 127.0.0.1:9000 0.0.0.0:* LISTEN

8、訪問測試
輸入http://serverip/

大功告成！

*附uwsgi啟動腳本
#cd /home/uwsgi
#vi uwsgiserver.sh

#!/bin/bashif [ $1 = start ];then psid=`ps aux|grep "uwsgi"|grep -v "grep"|wc -l` if [ $psid -gt 2 ];then echo "uwsgi is running!" exit 0 else /usr/bin/uwsgi -x /home/uwsgi/uwsgi.xml fi echo "Start uwsgi service [OK]"elif [ $1 = stop ];then killall -9 uwsgi echo "Stop uwsgi service [OK]"elif [ $1 = restart ];then killall -9 uwsgi /usr/bin/uwsgi -x /home/uwsgi/uwsgi.xml echo "Restart uwsgi service [OK]"else echo "Usages: sh uwsgiserver.sh [start|stop|restart]"fi

#sh uwsgiserver.sh start
[uWSGI] parsing config file /home/uwsgi/uwsgi.xml
Start uwsgi service [OK]

以下是補充：

1、MySQL-python 安裝錯誤如下
from setuptools import setup ImportError:

先安裝
python ez_setup.py

在安裝
python setup.py install

貼一下,方便其他兄弟了

2、我的nginx+uwsgi+django遇到大header的request，經常出現502，uwsgi報的是 invalid request header size,何解我的uwsgi配置為[uwsgi]socket = :8010master = truemodule = django_wsgiprocesses = 8home = /path/to/virtualenvharakiri = 20daemonize = /path/to/uwsgi.logpidfile = /path/to/uwsgi.pidpythonpath = /path/to/projectpythonpath = /path/to/uwsgibuffer-size = 32768reload-mercy = 8max-requests = 5000socket-timeout = 4

解決方法：大header可以修改nginx http head部分參數。

3、Nginx報502，但是uwsgi正常啟動端口9000也正常監聽。有可能是應用程序有錯誤導致。
