之前使用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、安装软件
1、安装pcre
cd /opt
wget ftp://ftp.csx.cam.ac.uk/pub/software/programming/pcre/pcre-8.31.tar.gz
tar zxvf pcre-8.31.tar.gz
cd pcre-8.31
./configure
make && make install
cd ..
2、安装nginx
tar zxvf nginx-1.2.4.tar.gz
cd nginx-1.2.4
./configure --prefix=/usr/local/nginx/ --with-http_stub_status_module --with-pcre=../pcre-8.31/
make && make install
3、yum安装mysql
yum -y install mysql*
/etc/init.d/mysqld start
4、安装python
wget http://www.python.org/ftp/python/2.7.3/Python-2.7.3.tar.bz2
tar jxvf Python-2.7.3.tar.bz2
cd Python-2.7.3
./configure
make && make install
改下yum的py版本，不然yum报错
sed -i '1s/\/usr\/bin\/python/\/usr\/bin\/python2.4/1' /usr/bin/yum
5、安装MySql-python
wget http://pypi.python.org/packages/source/M/MySQL-python/MySQL-python-1.2.3.tar.gz
cd MySQL-python-1.2.3.tar.gz
python setup.py install
6、安装Django
wget http://www.djangoproject.com/m/releases/1.4/Django-1.4.2.tar.gz
tar zxvf Django-1.4.2.tar.gz
cd Django-1.4.2
python setup.py install
7、安装uWSGI
wget http://projects.unbit.it/downloads/uwsgi-1.3.tar.gz
tar zxvf uwsgi-1.3.tar.gz
cd uwsgi-1.3
make
cp uwsgi /usr/bin
二、平台配置：项目位置：/opt/www/Purgesys
1、mkdir -p /opt/www/
创建项目方法：
django-admin.py startproject Purgesys
查看项目(出现以下文件结构说明项目已创建成功)
tree Purgesys
[root@localhost www]# tree Purgesys
Purgesys
|-- Purgesys
| |-- __init__.py
| |-- __init__.pyc
| |-- settings.py
| |-- settings.pyc
| |-- urls.py
| |-- urls.pyc
| `-- wsgi.py
|-- django_wsgi.py
|-- django_wsgi.pyc
`-- manage.py
1 directory, 10 files
2、nginx配置
cd /usr/local/nginx/conf
vim django_uwsgi.conf
server {
listen 80;
server_name 10.1.20.151;
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;
}
}
vim nginx.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
vim 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>2048</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
uwsgi: error while loading shared libraries: libpcre.so.1: cannot open shared object file: No such file or directory
解决方法：
64位系统 # ln -s /usr/local/lib/libpcre.so.1 /lib64
32位系统 # ln -s /usr/local/lib/libpcre.so.1 /lib
/usr/local/nginx/sbin/nginx
6、查看进程
[root@localhost ~]# ps -ef|grep uwsgi|grep -v grep
root 13035 1 0 10:25 ? 00:00:00 uwsgi -x /home/uwsgi/uwsgi.xml
root 13036 13035 0 10:25 ? 00:00:00 uwsgi -x /home/uwsgi/uwsgi.xml
root 13037 13035 0 10:25 ? 00:00:00 uwsgi -x /home/uwsgi/uwsgi.xml
root 13038 13035 0 10:25 ? 00:00:00 uwsgi -x /home/uwsgi/uwsgi.xml
root 13039 13035 0 10:25 ? 00:00:00 uwsgi -x /home/uwsgi/uwsgi.xml
root 13040 13035 0 10:25 ? 00:00:00 uwsgi -x /home/uwsgi/uwsgi.xml
root 13041 13035 0 10:25 ? 00:00:00 uwsgi -x /home/uwsgi/uwsgi.xml
root 13042 13035 0 10:25 ? 00:00:00 uwsgi -x /home/uwsgi/uwsgi.xml
root 13043 13035 0 10:25 ? 00:00:00 uwsgi -x /home/uwsgi/uwsgi.xml
7、访问测试
输入http://ip/
