Centos5.4+Nginx-0.8.50+UWSGI-0.9.6.2+Django-1.2.3搭建高性能WEB服务器
<p>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。</p>
<p>
<strong>一、安装平台</strong><br>
1、安装pcre</p>
<p>
</p>
<div class="codetitle">
<span><u>复制代码</u></span> 代码如下:</div>
<div class="codebody" id="code67501">
<br>
cd /home<br>
mkdir -p /home/install/nginx && cd /home/install/nginx<br>
wget http://ftp.exim.llorien.org/pcre/pcre-8.00.tar.gz<br>
tar -zxvf pcre-8.00.tar.gz<br>
cd pcre-8.00<br>
./configure<br>
make && make install<br>
cd ..</div>
<p>
</p>
<p>
2、安装nginx</p>
<p>
</p>
<div class="codetitle">
<span><u>复制代码</u></span> 代码如下:</div>
<div class="codebody" id="code59215">
<br>
wget http://nginx.org/download/nginx-0.8.50.tar.gz<br>
tar -zxvf nginx-0.8.50.tar.gz<br>
cd nginx-0.8.50/<br>
./configure --user=nobody --group=nobody --prefix=/usr/local/nginx --with-http_stub_status_module --with-cc-opt='-o3' --with-cpu-opt=opteron<br>
make && make install<br>
cd ..</div>
<p>
</p>
<p>
3、安装python&mysql-python</p>
<p>
</p>
<div class="codetitle">
<span><u>复制代码</u></span> 代码如下:</div>
<div class="codebody" id="code37189">
<br>
wget http://www.python.org/ftp/python/2.5.1/python-2.5.1.tgz<br>
tar -zxvf python-2.5.1.tgz<br>
cd python-2.5.1<br>
./configure && make && make install<br>
echo "export path=\$path:/usr/local/bin" >> /etc/profile<br>
source /etc/profile</div>
<p>
</p>
<p>
4、安装mysql-python</p>
<p>
</p>
<div class="codetitle">
<span><u>复制代码</u></span> 代码如下:</div>
<div class="codebody" id="code76710">
<br>
cd ../<br>
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<br>
cd mysql-python-1.2.2<br>
python setup.py install</div>
<p>
</p>
<p>
5、安装django</p>
<p>
</p>
<div class="codetitle">
<span><u>复制代码</u></span> 代码如下:</div>
<div class="codebody" id="code58147">
<br>
wget http://www.djangoproject.com/download/1.2.3/tarball/<br>
tar -zxvf django-1.2.3.tar.gz<br>
cd django-1.2.3<br>
python setup.py install<br>
cd ..</div>
<p>
</p>
<p>
6、安装uwsgi</p>
<p>
</p>
<div class="codetitle">
<span><u>复制代码</u></span> 代码如下:</div>
<div class="codebody" id="code40393">
<br>
wget http://projects.unbit.it/downloads/uwsgi-0.9.6.2.tar.gz<br>
tar -zxvf uwsgi-0.9.6.2.tar.gz<br>
cd uwsgi-0.9.6.2<br>
make<br>
cp uwsgi /usr/bin</div>
<p>
</p>
<p>
<strong>二、平台配置</strong></p>
<p>
1、平台环境说明<br>
1.1、项目位置：/opt/www/purgesys<br>
创建项目方法：</p>
<p>
</p>
<div class="codetitle">
<span><u>复制代码</u></span> 代码如下:</div>
<div class="codebody" id="code67096">
<br>
cd /opt/www<br>
django-admin.py startproject purgesys</div>
<p>
</p>
<p>
1.2、查看项目(出现以下文件结构说明项目已创建成功)<br>
#tree purgesys</p>
<p>
</p>
<div class="codetitle">
<span><u>复制代码</u></span> 代码如下:</div>
<div class="codebody" id="code86986">
<br>
purgesys<br>
|-- __init__.py<br>
|-- manage.py<br>
|-- settings.py<br>
`-- urls.py</div>
<p>
</p>
<p>
2、nginx相关配置</p>
<p>
#cd /usr/local/nginx/conf<br>
#vi django_uwsgi.conf</p>

4、创建应用模块<br>
cd /opt/www/purgesys<br>
vi django_wsgi.py</p>
<div class="jb51code">
<div>
<div class="syntaxhighlighterplain" id="highlighter_714740">
<div class="toolbar">
<span>?</span>
</div>
<table border="0" cellpadding="0" cellspacing="0"><tbody><tr>
<td class="gutter">
<div class="line number1 index0 alt2">
1</div>
<div class="line number2 index1 alt1">
2</div>
<div class="line number3 index2 alt2">
3</div>
<div class="line number4 index3 alt1">
4</div>
</td>
<td class="code">
<div class="container">
<div class="line number1 index0 alt2">
<code class="plain plain">import os</code>
</div>
<div class="line number2 index1 alt1">
<code class="plain plain">os.environ['django_settings_module'] = 'purgesys.settings'</code>
</div>
<div class="line number3 index2 alt2">
<code class="plain plain">import django.core.handlers.wsgi</code>
</div>
<div class="line number4 index3 alt1">
<code class="plain plain">application = django.core.handlers.wsgi.wsgihandler()</code>
</div>
</div>
</td>
</tr></tbody></table>
</div>
</div>
</div>
<p>
5、启动服务<br>
#/usr/bin/uwsgi -x /home/uwsgi/uwsgi.xml<br>
#/usr/local/nginx/sbin/nginx</p>
<p>
6、查看进程<br>
## ps -ef|grep uwsgi|grep -v grep</p>
<p>
</p>
<div class="codetitle">
<span><u>复制代码</u></span> 代码如下:</div>
<div class="codebody" id="code53874">
<br>
root 21652 1 0 17:12 ? 00:00:00 /usr/bin/uwsgi -x /home/uwsgi/uwsgi.xml<br>
root 21653 21652 0 17:12 ? 00:00:00 /usr/bin/uwsgi -x /home/uwsgi/uwsgi.xml<br>
root 21654 21652 0 17:12 ? 00:00:00 /usr/bin/uwsgi -x /home/uwsgi/uwsgi.xml<br>
root 21655 21652 0 17:12 ? 00:00:00 /usr/bin/uwsgi -x /home/uwsgi/uwsgi.xml<br>
root 21656 21652 0 17:12 ? 00:00:00 /usr/bin/uwsgi -x /home/uwsgi/uwsgi.xml<br>
root 21657 21652 0 17:12 ? 00:00:00 /usr/bin/uwsgi -x /home/uwsgi/uwsgi.xml<br>
root 21658 21652 0 17:12 ? 00:00:00 /usr/bin/uwsgi -x /home/uwsgi/uwsgi.xml<br>
root 21659 21652 0 17:12 ? 00:00:00 /usr/bin/uwsgi -x /home/uwsgi/uwsgi.xml<br>
root 21660 21652 0 17:12 ? 00:00:00 /usr/bin/uwsgi -x /home/uwsgi/uwsgi.xml</div>
<p>
</p>
<p>
7、监听端口<br>
## netstat -an|grep 9000<br>
引用</p>
<p>
tcp 0 127.0.0.1:9000 0.0.0.0:* listen</p>
<p>
8、访问测试<br>
输入http://serverip/</p>
<p>
<img style="max-width:100%!important;height:auto!important;"title="Centos5.4+Nginx-0.8.50+UWSGI-0.9.6.2+Django-1.2.3搭建高性能WEB服务器" alt="Centos5.4+Nginx-0.8.50+UWSGI-0.9.6.2+Django-1.2.3搭建高性能WEB服务器" src="https://zhuji.jb51.net/uploads/img/202305/c888243cce7584c5c5ed30f070f59592.jpg"></p>

<span>以下是补充：</span></p>
<p>
1、mysql-python 安装错误如下<br>
from setuptools import setup importerror:</p>
<p>
先安装<br>
python ez_setup.py</p>
<p>
在安装<br>
python setup.py install</p>
<p>
贴一下,方便其他兄弟了</p>
<p>
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</p>
<p>
解决方法：大header可以修改nginx http head部分参数。</p>
<p>
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。</p>
