nginx连接uwsgi使用web.py框架构造pythonweb项目

相关页面：
http://webpy.org/install
http://uwsgi-docs.readthedocs.org/en/latest/WSGIquickstart.html
http://projects.unbit.it/uwsgi/wiki/Example
uwsgi的安装需要python-devel，可以使用yum search python-devel进行查找
没有的话可以到
http://www.rpmfind.net/进行相关rpm包进行查找

uwsgi安装：
wget http://projects.unbit.it/downloads/uwsgi-latest.tar.gz
tar zxvf uwsgi-latest.tar.gz
cd <dir>
make
生成可执行的二进制文件uwsgi
文件位置：
mkdir /home/uwsgi
mv uwsgi /home/uwsgi/

web.py安装：
http://webpy.org/install
python setup.py install 在解压的tar包中进行安装

简单运行文件：
vim test.py ：

/usr/bin/python
import web
urls=('/(.*)','hello')
app=web.application(urls,globals())
class hello:
    def GET(self,name):
        if not name:
            name='World'
        return 'Hello'+name+'!'    
application=app.wsgifunc()

 uwsgi启动方式：
/home/uwsgi/uwsgi --socket 127.0.0.1:9000 --chdir /home/project/maintence.xxx.xxx.com/ -w test
/home/project/maintence.xxx.xxx.com/目录为test.py所在目录

nginx配置：
server {
        listen  80;
        server_name  maintence.xxx.xxx.com;
        access_log  logs/access_maintence.xxx.xxx.com.log  main;
        error_log   logs/error_maintence.xxx.xxx.com.log   warn;
        root         /home/nginx/html/maintence.xxx.xxx.com;
        location / {
            include uwsgi_params;
            uwsgi_pass 127.0.0.1:9000;
        }
}

以上配置可以完成nginx-uwsgi的直连，使用web.py框架
uwsgi可以使用配置文件的方式进行配置：
<whousexml>
    <uwsgi id='e-commerce'>
        <socket>127.0.0.1:9000</socket>
        <chdir>%d/../src</chdir>
        <module>test</module>
        <master />
        <workers>4</workers>
        <cpu-affinity>2</cpu-affinity>
        <daemonize>%d/../log/uwsgi.log</daemonize>
        <pidfile>%d/../log/uwsgi.pid</pidfile>
    </uwsgi>
</whousexml>

启动方式：
uwsgi_home='/home/uwsgi'
service_home='/home/project/maintencexxx.xxx.com'
service_id='xxx'
$uwsgi_home/uwsgi --xml $service_home/conf/uwsgi.conf:$service_id
停止：
$uwsgi_home/uwsgi --stop $pid_file
reload：
$uwsgi_home/uwsgi --reload $pid_file

一个简单的启动脚本：

if [ `whoami` != appuser ]
then
    echo 'This script need appuser user'
    exit 1
fi
if [ $# -ne 1 ]; then
    echo "Usage:$0 {stop|start|restart|reload}"
    exit -1
fi
uwsgi_home='/home/uwsgi'
service_home='/home/project/maintence.xxx.xxx.com'
service_id='xxx'
pid_file=$service_home/log/uwsgi.pid
pid=$(cat $pid_file)

function start(){
    $uwsgi_home/uwsgi --xml $service_home/conf/uwsgi.conf:$service_id
}
function stop(){
    $uwsgi_home/uwsgi --stop $pid_file
    sleep 3
    ( netstat -tlunp | grep $pid | grep -q uwsgis ) 2> /dev/null
    if [ $? == 0 ];then
        kill -9 $pid
        sleep 1
    fi
}
function reload(){
    $uwsgi_home/uwsgi --reload $pid_file
}

case $1 in 
    stop)
        stop
    ;;
    start)
        start
    ;;
    restart)
        stop
        start
    ;;
    reload)
        reload
    ;;
