Centos5.4+Nginx-0.8.50+UWSGI-0.9.6.2+Django-1.2.3搭建高性能WEB服务器

Centos5.4+Nginx-0.8.50+UWSGI-0.9.6.2+Django-1.2.3搭建高性能WEB服务器

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

引用
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

引用
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

引用
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

引用
cd ../
wget mysql-python/mysql-python/1.2.2/MySQL-python-1.2.2.tar.gz?r=&ts=1285248455&use_mirror=nchc">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

引用
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

引用
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：

引用
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

引用
Purgesys
|– __init__.py
|– manage.py
|– settings.py
`– urls.py

2、Nginx相关配置
#cd /usr/local/nginx/conf
#vi django_uwsgi.conf

view plaincopy to clipboardprint?
# 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;
}
}
# 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;
}
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

view plaincopy to clipboardprint?
<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>
<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

view plaincopy to clipboardprint?
import os
os.environ[DJANGO_SETTINGS_MODULE] = ‘Purgesys.settings’
import django.core.handlers.wsgi
application = django.core.handlers.wsgi.WSGIHandler()
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
