Linux系统上Nginx+Python的web.py与Django框架环境


            1.编译nginx

在网上买了一本《实战nginx-取代Apache的高性能服务器》，写的比较浅，主要是些配置方面的东西，不过却正是目前我所需要的。由于需要支持https和rewrite，所以除了nginx的源码之外，又下载了 openssl-0.9.8r.tar.gz 和 pcre-8.12.tar.gz，把他们和nginx-1.0.4.tar.gz放到同一个目录。

为了方便编译，笔者写了一个脚本，代码如下:





#!/bin/bash

 

#=============================================================================

#脚本所在绝对目录

abs_path(){

 local path=$1

 local basename=$( basename $path )

 local dirname=$( dirname $path )

 cd $dirname

 if [ -h $basename ]; then

  path=$( readlink $basename )

  abs_path $path

 else

  pwd

 fi

}

 

#=============================================================================

#依赖的目录

src_base_dir=$( abs_path $0 )

src_openssl_dir=$src_base_dir'/openssl-0.9.8r'

src_pcre_dir=$src_base_dir'/pcre-8.12'

src_nginx_dir=$src_base_dir'/nginx-1.0.4'

 

#=============================================================================

#目标的目录

dest_base_dir=$src_base_dir'/release'

dest_nginx_dir=$dest_base_dir'/nginx'

 

#=============================================================================

#把所有的tar.gz解压

find . -name "*.tar.gz" | xargs -IX tar zxvf X

 

#=============================================================================

#编译nginx

cd $src_nginx_dir

chmod u+x ./configure

./configure --with-http_stub_status_module --with-http_ssl_module --with-openssl=$src_openssl_dir --with-pcre=$src_pcre_dir --prefix=$dest_nginx_dir

make && make install







2.配置nginx

在server配置项下增加







location / {

 #这两种方法都可以，只不过spawn-cgi启动的方法不同

 #fastcgi_pass 127.0.0.1:9002;

 fastcgi_pass unix:webpy.sock;

 

 fastcgi_param REQUEST_METHOD $request_method;

 fastcgi_param QUERY_STRING $query_string;

 fastcgi_param CONTENT_TYPE $content_type;

 fastcgi_param CONTENT_LENGTH $content_length;

 fastcgi_param GATEWAY_INTERFACE CGI/1.1;

 fastcgi_param SERVER_SOFTWARE nginx/$nginx_version;

 fastcgi_param REMOTE_ADDR $remote_addr;

 fastcgi_param REMOTE_PORT $remote_port;

 fastcgi_param SERVER_ADDR $server_addr;

 fastcgi_param SERVER_PORT $server_port;

 fastcgi_param SERVER_NAME $server_name;

 fastcgi_param SERVER_PROTOCOL $server_protocol;

 fastcgi_param SCRIPT_FILENAME $fastcgi_script_name;

 fastcgi_param PATH_INFO $fastcgi_script_name;

}





这里的3个location配置分别解决了，与python进程通信、django后台管理端样式存放、网站样式存放的问题。对照着apache的配置来看，就很容易明白了







WSGIPythonEggs /tmp

<VirtualHost *>

 ServerName fuload.qq.com

 WSGIScriptAlias / /home/dantezhu/htdocs/fuload/conf/setting.wsgi

 <Directory />

  Options FollowSymLinks

  AllowOverride

  Order allow,deny 

  Allow from all 

 </Directory>

 <Directory "/home/dantezhu/htdocs/fuload/mysite">

  Order Deny,Allow 

  Deny from all 

 </Directory>

 Alias /admin_media "/usr/local/lib/python2.7/site-packages/django/contrib/admin/media"

 <Directory "/usr/local/lib/python2.7/site-packages/django/contrib/admin/media">

  Order allow,deny 

  Options Indexes

  Allow from all 

  IndexOptions FancyIndexing

 </Directory>

 

 #AliasMatch /site_media/(.*\.(css|gif|png|jpg|jpeg)) /home/dantezhu/htdocs/fuload/media/$1 

 Alias /site_media /home/dantezhu/htdocs/fuload/media/

 <Directory "/home/dantezhu/htdocs/fuload/media/">

  Order allow,deny 

  Options Indexes

  Allow from all 

  IndexOptions FancyIndexing

 </Directory>

</VirtualHost>





3.安装fastcgi依赖

需要到 http://trac.saddi.com/flup下载安装，之后fastcgi才能够正常启动。

4.启动django

创建django project的过程我们就不说了，只列出启动/停止的命令:

启动:







#python manage.py runfcgi daemonize=true pidfile=`pwd`/django.pid host=127.0.0.1 port=9001 maxrequests=1 &

python manage.py runfcgi daemonize=true pidfile=`pwd`/django.pid socket=/home/dantezhu/nginx/sbin/django.sock maxrequests=1 &





停止:







kill -9 `cat django.pid`





启动nginx

启动:







./nginx -p /home/dantezhu/nginx/





停止:







kill -QUIT `cat ../logs/nginx.pid`





重新载入配置:







./nginx -t -c `pwd`/../conf/nginx.conf

kill -HUP `cat ../logs/nginx.pid`





成功显示了django的后台界面:

PPPPPPPPPPPPPPPPPPPPP1

5.部署web.py版

安装依赖

spawn-cgi

flup

配置nginx

在server配置项下增加







location / {

 #这两种方法都可以，只不过spawn-cgi启动的方法不同

 #fastcgi_pass 127.0.0.1:9002;

 fastcgi_pass unix:webpy.sock;

 

 fastcgi_param REQUEST_METHOD $request_method;

 fastcgi_param QUERY_STRING $query_string;

 fastcgi_param CONTENT_TYPE $content_type;

 fastcgi_param CONTENT_LENGTH $content_length;

 fastcgi_param GATEWAY_INTERFACE CGI/1.1;

 fastcgi_param SERVER_SOFTWARE nginx/$nginx_version;

 fastcgi_param REMOTE_ADDR $remote_addr;

 fastcgi_param REMOTE_PORT $remote_port;

 fastcgi_param SERVER_ADDR $server_addr;

 fastcgi_param SERVER_PORT $server_port;

 fastcgi_param SERVER_NAME $server_name;

 fastcgi_param SERVER_PROTOCOL $server_protocol;

 fastcgi_param SCRIPT_FILENAME $fastcgi_script_name;

 fastcgi_param PATH_INFO $fastcgi_script_name;

}





一个简单的index.py







#!/usr/bin/python

# -*- coding: utf-8 -*-

 

import web 

 

urls = ("/.*", "hello")

app = web.application(urls, globals())

 

class hello:

 def GET(self):

  return 'Hello, world!'

 

if __name__ == "__main__":

 web.wsgi.runwsgi = lambda func, addr=None: web.wsgi.runfcgi(func, addr)

 app.run()





并执行:







chmod +x index.py





.启动web.py

启动:







#spawn-fcgi -P `pwd`/webpy.pid -f /home/dantezhu/htdocs/ngx_web/index.py -a 127.0.0.1 -p 9002 &

spawn-fcgi -P `pwd`/webpy.pid -f /home/dantezhu/htdocs/ngx_web/index.py -s /home/dantezhu/nginx/sbin/webpy.sock &





停止:







kill -9 `cat webpy.pid`





启动nginx

加入到rc.local中，自动启动







/home/dantezhu/nginx/sbin/start.sh

sudo -u dantezhu /home/dantezhu/htdocs/ngx_django/mysite/start.sh

sudo -u dantezhu /home/dantezhu/htdocs/ngx_web/start.sh
