搭建python的web环境 Centos5.4+Nginx-0.8.50+UWSGI-0.9.6.2+Django-1.2.3搭建高性能WEB服务器环境

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

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

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

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

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

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

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：

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

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 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

#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

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

tcp 0 127.0.0.1:9000 0.0.0.0:* LISTEN

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]
