1、nginx的安装。这里采用nginx-1.6.0，建立一个shell脚本然后执行。

#!/bin/bash
nginx_version="nginx-1.6.0"
yum -y install gcc gcc-c++ pcre pcre-devel openssl openssl-devel
cd soft
tar zxvf $nginx_version".tar.gz" 
cd $nginx_version
./configure   --error-log-path=/var/log/nginx/error.log --http-log-path=/var/log/nginx/access.log --with-http_stub_status_module --with-http_ssl_module
make
make install
cp /usr/local/nginx/conf/nginx.conf /usr/local/nginx/conf/nginx.conf.bak
/usr/local/nginx/sbin/nginx  -c /usr/local/nginx/conf/nginx.conf
echo "/usr/local/nginx/sbin/nginx" >>/etc/rc.local
cd ..
rm -rf $nginx_version

这里是iptables的设置

iptables -F
iptables -A INPUT -m state --state NEW -m tcp -p tcp --dport 3306 -j ACCEPT
iptables -A INPUT -p tcp -m tcp --dport 80 -j ACCEPT
iptables -A INPUT -p tcp -m tcp --dport 22 -j ACCEPT
iptables -A INPUT -i lo -j ACCEPT
iptables -A INPUT -m state --state RELATED,ESTABLISHED -j ACCEPT
iptables -P INPUT DROP
service iptables save

2.mysql的安装，在这里mysql使用的是5.6.14，新建一个shell脚本粘贴上下面的文字

#!/bin/bash
mysql_version="mysql-5.6.14"
yum -y install vim  libevent*  libtool* autoconf* libstd* ncurse* bison* openssl*
cd soft
tar zxvf cmake-2.8.12.1.tar.gz
cd cmake-2.8.12.1
./configure && make && make install
cd ..
rm -rf cmake-2.8.12.1
tar zxvf $mysql_version".tar.gz"
cd $mysql_version
cmake -DCMAKE_INSTALL_PREFIX=/usr/local/mysql -DMYSQL_DATADIR=/usr/local/mysql/data -DSYSCONFDIR=/etc -DWITH_MYISAM_STORAGE_ENGINE=1 -DWITH_INNOBASE_STORAGE_ENGINE=1 -DWITH_MEMORY_STORAGE_ENGINE=1 -DWITH_READLINE=1 -DMYSQL_UNIX_ADDR=/var/lib/mysql/mysql.sock -DMYSQL_TCP_PORT=3306 -DENABLED_LOCAL_INFILE=1 -DWITH_PARTITION_STORAGE_ENGINE=1 -DEXTRA_CHARSETS=all -DDEFAULT_CHARSET=utf8 -DDEFAULT_COLLATION=utf8_general_ci
make && make install
groupadd mysql
useradd -g mysql mysql
chown -R mysql:mysql /usr/local/mysql
cd /usr/local/mysql
scripts/mysql_install_db --basedir=/usr/local/mysql --datadir=/usr/local/mysql/data --user=mysql --ldata=/var/lib/mysql
cp support-files/mysql.server /etc/init.d/mysql
chkconfig mysql on
chmod 755 /etc/init.d/mysql
service mysql start
echo "PATH=/usr/local/mysql/bin:$PATH" >> /etc/profile
echo "export PATH" >> /etc/profile
source /etc/profile
mysqladmin -u root password 123456
cd -
cd ..
rm -rf $mysql_version

3.开始安装django，这里使用的是django最新稳定版1.6.5

安装必要的软件包

yum groupinstall "Development tools"
yum install zlib-devel bzip2-devel pcre-devel openssl-devel ncurses-devel sqlite-devel readline-devel tk-devel python-devel libxml2  libxml2-devel  python-setuptools  zlib-devel wget openssl-devel pcre pcre-devel sudo gcc make autoconf automake

安装pip软件

wget http://pypi.python.org/packages/source/p/pip/pip-1.0.2.tar.gz --no-check-certificate  
tar xvfz pip-1.0.2.tar.gz   
cd pip-1.0.2  
python setup.py  install

pip --version  查看pip是否安装

安装uwsgi

pip install uwsgi
uwsgi --version

新建web.py文件，内容如下：

def application(env, start_response):
    start_response('200 OK', [('Content-Type','text/html')])
    return "Hello World"

然后在终端运行：

uwsgi --http :8001 --wsgi-file test.py

在浏览器内输入：http://127.0.0.1:8001，看是否有“Hello World”输出。

安装django

pip install django

django-admin.py startproject demosite
cd demosite

python manage.py runserver 0.0.0.0:8002

在浏览器内输入：http://127.0.0.1:8002，检查django是否运行正常。

配置uwsgi

在/ect/目录下新建uwsgi9090.ini，添加如下配置：

[uwsgi]
socket = 127.0.0.1:9090
master = true         //主进程
vhost = true          //多站模式
workers = 2           //子进程数
reload-mercy = 10     
vacuum = true         //退出、重启时清理文件
max-requests = 1000   
limit-as = 512
buffer-sizi = 30000
pidfile = /var/run/uwsgi9090.pid    //pid文件，用于下面的脚本启动、停止该进程
daemonize = /website/uwsgi9090.log

设置uwsgi开机启动，在/ect/init.d/目录下新建uwsgi9090文件，内容如下：

#! /bin/sh
# chkconfig: 2345 55 25
# Description: Startup script for uwsgi webserver on Debian. Place in /etc/init.d and
# run 'update-rc.d -f uwsgi defaults', or use the appropriate command on your
# distro. For CentOS/Redhat run: 'chkconfig --add uwsgi'
 
### BEGIN INIT INFO
# Provides:          uwsgi
# Required-Start:    $all
# Required-Stop:     $all
# Default-Start:     2 3 4 5
# Default-Stop:      0 1 6
# Short-Description: starts the uwsgi web server
# Description:       starts uwsgi using start-stop-daemon
### END INIT INFO
 
# Author:   licess
# website:  http://lnmp.org
 
PATH=/usr/local/sbin:/usr/local/bin:/sbin:/bin:/usr/sbin:/usr/bin
DESC="uwsgi daemon"
NAME=uwsgi9090
DAEMON=/usr/bin/uwsgi
CONFIGFILE=/etc/$NAME.ini
PIDFILE=/var/run/$NAME.pid
SCRIPTNAME=/etc/init.d/$NAME
 
set -e
[ -x "$DAEMON" ] || exit 0
 
do_start() {
    $DAEMON $CONFIGFILE || echo -n "uwsgi already running"
}
 
do_stop() {
    $DAEMON --stop $PIDFILE || echo -n "uwsgi not running"
    rm -f $PIDFILE
    echo "$DAEMON STOPED."
}
 
do_reload() {
    $DAEMON --reload $PIDFILE || echo -n "uwsgi can't reload"
}
 
do_status() {
    ps aux|grep $DAEMON
}
 
case "$1" in
 status)
    echo -en "Status $NAME: \n"
    do_status
 ;;
 start)
    echo -en "Starting $NAME: \n"
    do_start
 ;;
 stop)
    echo -en "Stopping $NAME: \n"
    do_stop
 ;;
 reload|graceful)
    echo -en "Reloading $NAME: \n"
    do_reload
 ;;
 *)
    echo "Usage: $SCRIPTNAME {start|stop|reload}" >&2
    exit 3
 ;;
esac
 
exit 0

设置uwsgi开机启动

chkconfig --add uwsgi9090 
chkconfig uwsgi9090 on

修改nginx的conf文件

server {
        listen       80;
        server_name  localhost;
        
        location / {            
            include  uwsgi_params;
            uwsgi_pass  127.0.0.1:9090;              //必须和uwsgi中的设置一致
            uwsgi_param UWSGI_SCRIPT demosite.wsgi;  //入口文件，即wsgi.py相对于项目根目录的位置，“.”相当于一层目录
            uwsgi_param UWSGI_CHDIR /demosite;       //项目根目录
            index  index.html index.htm;
            client_max_body_size 35m;
        }
    }

service uwsgi9090 start

在浏览器输入：http://127.0.0.1，恭喜你可以看到django的“It work”了~

安装mysql-python

pip install mysql-python

测试django与mysql的连接性

在项目中运行python manage.py shell

然后

from django.db import connection
cursor=connection.cursor()
