Centos 5.8+Nginx-1.4.1+Uwsgi+Django 高性能WEB服务器搭建

系统环境:Centos 5.8_64
相关站点:
Pcre: http://ftp.exim.llorien.org/pcre/
Nginx: http://nginx.org/download/nginx-1.4.1.tar.gz
Uwsgi: http://projects.unbit.it/downloads/uwsgi-1.4.9.tar.gz
Python: http://www.python.org/getit/
Mysql-Python: http://sourceforge.net/projects/mysql-python/files/mysql-python/1.2.3/
Django: https://www.djangoproject.com/download/
virtualenv: https://pypi.python.org/pypi/virtualenv#downloads

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.

安装部署:
一:安装PCRE
yum install -y pcre-devel
tar zvfx pcre-8.32.tar.gz
cd pcre-8.32
./configure
make
make install
cd ..

二:安装Nginx
tar zvfx nginx-1.4.1.tar.gz
cd nginx-1.4.1
./configure --prefix=/usr/local/nginx-1.4.1 \
--with-http_stub_status_module \
--with-http_ssl_module \
--with-pcre
make && make install
cd ..
groupadd develop -g 507
useradd -g develop www -u 2000

三:安装Python
tar zvfx Python-2.7.5.tgz
cd Python-2.7.5
./configure
make && make install
cd ..

四:安装相关依赖
tar zxvf mysql-5.1.68.tar.gz
cd mysql-5.1.68
./configure --prefix=/usr/local/mysql-5.1.68 \
--without-server \
--with-extra-charsets=all
make
make install
cd ..
echo "export PATH=/usr/local/mysql-5.1.68/bin:\$PATH" >> /etc/profile
source /etc/profile
echo "/usr/local/mysql-5.1.68/lib/mysql" > /etc/ld.so.conf.d/mysql.conf
ldconfig

tar zvfx setuptools-0.6c9.tar.gz
cd setuptools-0.6c9
python setup.py install
cd ..

五:安装Mysql-Python
tar zvfx MySQL-python-1.2.3.tar.gz
cd MySQL-python-1.2.3
python setup.py install
cd ..

六:安装Django
tar zvfx Django-1.5.1.tar.gz
cd Django-1.5.1
python setup.py install
cd ..

七:安装uWSGI
tar zvfx uwsgi-1.4.9.tar.gz
cd uwsgi-1.4.9
make
cp uwsgi /usr/bin
cd ..
ln -s /usr/local/lib/libpcre.so.1 /lib64

VirtualEnv用于在一台机器上创建多个独立的python运行环境,VirtualEnvWrapper为前
者提供了一些便利的命令行上的封装.
使用 VirtualEnv 的理由:
隔离项目之间的第三方包依赖,如A项目依赖django1.2.5,B项目依赖django1.3.
为部署应用提供方便,把开发环境的虚拟环境打包到生产环境即可,不需要在服务器上再折腾一翻.
tar zvfx virtualenv-1.9.1.tar.gz
cd virtualenv-1.9.1
python setup.py install
cd ..

八:平台环境配置
创建项目:
[root@CN-BJ-MT-02 ~]#mkdir -p /data/python_web
[root@CN-BJ-MT-02 python_web]django-admin.py startproject phone

如下说明创建成功:
[root@CN-BJ-MT-02 python_web]# tree phone/
phone/
|-- manage.py
`-- phone
|-- __init__.py
|-- settings.py
|-- urls.py
`-- wsgi.py
