一、安装平台
1、安装pcre

复制代码 代码如下:

cd /home
mkdir -p /home/install/nginx && cd /home/install/nginx
wget http://ftp.exim.llorien.org/pcre/pcre-8.00.tar.gz
tar -zxvf pcre-8.00.tar.gz
cd pcre-8.00
./configure
make && make install
cd ..

2、安装nginx

复制代码 代码如下:

wget http://nginx.org/download/nginx-0.8.50.tar.gz
tar -zxvf nginx-0.8.50.tar.gz
cd nginx-0.8.50/
./configure --user=nobody --group=nobody --prefix=/usr/local/nginx --with-http_stub_status_module --with-cc-opt='-o3' --with-cpu-opt=opteron
make && make install
cd ..

3、安装python&mysql-python

复制代码 代码如下:

wget http://www.python.org/ftp/python/2.5.1/python-2.5.1.tgz
tar -zxvf python-2.5.1.tgz
cd python-2.5.1
./configure && make && make install
echo "export path=\$path:/usr/local/bin" >> /etc/profile
source /etc/profile

4、安装mysql-python

复制代码 代码如下:

cd ../
wget http://downloads.sourceforge.net/project/mysql-python/mysql-python/1.2.2/mysql-python-1.2.2.tar.gz?r=&ts=1285248455&use_mirror=nchc
cd mysql-python-1.2.2
python setup.py install

5、安装django

复制代码 代码如下:

wget http://www.djangoproject.com/download/1.2.3/tarball/
tar -zxvf django-1.2.3.tar.gz
cd django-1.2.3
python setup.py install
cd ..

6、安装uwsgi

复制代码 代码如下:

wget http://projects.unbit.it/downloads/uwsgi-0.9.6.2.tar.gz
tar -zxvf uwsgi-0.9.6.2.tar.gz
cd uwsgi-0.9.6.2
make
cp uwsgi /usr/bin

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：

复制代码 代码如下:

cd /opt/www
django-admin.py startproject purgesys

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

复制代码 代码如下:

purgesys
|-- __init__.py
|-- manage.py
|-- settings.py
`-- urls.py

2、nginx相关配置

#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

 127.0.0.1:9000 200 true /usr/local/nginx/uwsgi.pid 8 /opt/www/purgesys /opt/www/ django_wsgi true true true true 6048 /opt/www/logs/django.log

4、创建应用模块
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、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

复制代码 代码如下:

root 21652 1 0 17:12 ? 00:00:00 /usr/bin/uwsgi -x /home/uwsgi/uwsgi.xml
root 21653 21652 0 17:12 ? 00:00:00 /usr/bin/uwsgi -x /home/uwsgi/uwsgi.xml
root 21654 21652 0 17:12 ? 00:00:00 /usr/bin/uwsgi -x /home/uwsgi/uwsgi.xml
root 21655 21652 0 17:12 ? 00:00:00 /usr/bin/uwsgi -x /home/uwsgi/uwsgi.xml
root 21656 21652 0 17:12 ? 00:00:00 /usr/bin/uwsgi -x /home/uwsgi/uwsgi.xml
root 21657 21652 0 17:12 ? 00:00:00 /usr/bin/uwsgi -x /home/uwsgi/uwsgi.xml
root 21658 21652 0 17:12 ? 00:00:00 /usr/bin/uwsgi -x /home/uwsgi/uwsgi.xml
root 21659 21652 0 17:12 ? 00:00:00 /usr/bin/uwsgi -x /home/uwsgi/uwsgi.xml
root 21660 21652 0 17:12 ? 00:00:00 /usr/bin/uwsgi -x /home/uwsgi/uwsgi.xml

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://serverip/

*附uwsgi启动脚本
#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。
