运维进行时

     之前一直使用Nginx+Fastcgi来搭建python web服务器，本文介绍Nginx+UWSGI组合来实现。uWSGI 是一个快速的、纯C语言开发的、自维护的、对开发者友好的WSGI服务器，旨在提供专业的 Python web应用发布和开发。它更符合python web的标准协议，速度要比Fastcgi要快、性能更加稳定。
一、安装平台
1、安装pcre

2、安装Nginx

3、安装python&Mysql-python

4、安装MySql-python

5、安装Django

6、安装uWSGI

二、平台配置
1、平台环境说明
  1.1、项目位置：/opt/www/Purgesys
   创建项目方法：

  1.2、查看项目(出现以下文件结构说明项目已创建成功)
  #tree Purgesys

2、Nginx相关配置
#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默认已添加uwsgi输出头支持
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、创建应用模块
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、启动服务
#/usr/bin/uwsgi -x /home/uwsgi/uwsgi.xml
#/usr/local/nginx/sbin/nginx

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

7、监听端口
#[liuts@webserver nginx]# netstat -an|grep 9000

8、访问测试
输入http://serverip/

大功告成！

*附uwsgi启动脚本
#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]
