之前一直使用Nginx+Fastcgi來搭建python web服務(wù)器，本文介紹Nginx+UWSGI組合來實現(xiàn)。uWSGI 是一個快速的、純C語言開發(fā)的、自維護的、對開發(fā)者友好的WSGI服務(wù)器，旨在提供專業(yè)的 Python web應(yīng)用發(fā)布和開發(fā)。它更符合python web的標準協(xié)議，速度要比Fastcgi要快、性能更加穩(wěn)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(huán)境說明
  1.1、項目位置：/opt/www/Purgesys
   創(chuàng)建項目方法：

  1.2、查看項目(出現(xiàn)以下文件結(jié)構(gòu)說明項目已創(chuàng)建成功)
  #tree Purgesys

2、Nginx相關(guān)配置

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

# Django project
server {
        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(chuàng)建應(yīng)用模塊
cd /opt/www/Purgesys
vi django_wsgi.py

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

5、啟動服務(wù)
#/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(jiān)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/bash
if [ $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(jīng)常出現(xiàn)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(shù)。

3、Nginx報502，但是uwsgi正常啟動端口9000也正常監(jiān)聽。有可能是應(yīng)用程序有錯誤導(dǎo)致。
