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
引用
tcp 0 127.0.0.1:9000 0.0.0.0:* listen
8、访问测试
输入http://www.lhsxpumps.com/_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]

以下是补充:
1、mysql-python 安装错误如下
from setuptools import setup importerror:
先安装
python ez_setup.py
在安装
python setup.py install
贴一下,方便其他兄弟了
2、我的nginx+uwsgi+django遇到大header的request,经常出现502,uwsgi报的是 invalid request header size,何解我的uwsgi配置为[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
解决方法:大header可以修改nginx http head部分参数。
3、nginx报502,但是uwsgi正常启动端口9000也正常监听。有可能是应用程序有错误导致。
