webpy + nginx + fastcgi 构建python应用

1.准备环境

CentOs  6.3

nginx-1.4.2.tar.gz            http://nginx.org/download/nginx-1.4.2.tar.gz

openssl-1.0.1c.tar.gz       http://www.openssl.org/source/openssl-1.0.1c.tar.gz

pcre-8.34.tar.gz              ftp://ftp.csx.cam.ac.uk/pub/software/programming/pcre/pcre-8.34.tar.gz

spawn-fcgi-1.6.4.tar.gz    http://download.lighttpd.net/spawn-fcgi/releases-1.6.x/spawn-fcgi-1.6.4.tar.gz

zlib-1.2.8.tar.gz              http://zlib.net/zlib-1.2.8.tar.gz

flup-1.0.2.tar.gz              http://www.saddi.com/software/flup/dist/flup-1.0.2.tar.gz

yum -y install gcc automake autoconf libtool make

yum install gcc gcc-c++   python-setuptools  python-pip

pip  install  web.py

2.安装

2.1 zlib安装

tar zxvf zlib-1.2.8.tar.gz

cd zlib-1.2.8

./configure

make && make  install

2.2 pcre安装

tar zxvf pcre-8.34.tar.gz

cd pcre-8.34

./configure 

make && make install

2.3 nginx安装

tar zxvf nginx-1.4.2.tar.gz 

cd nginx-1.4.2

./configure --sbin-path=/usr/local/nginx/nginx 

--conf-path=/usr/local/nginx/nginx.conf 

--pid-path=/usr/local/nginx/nginx.pid 

--with-http_ssl_module  

--with-pcre=../pcre-8.34 --with-zlib=../zlib-1.2.8 --with-openssl=../openssl-1.0.1c

make && make install

3.测试nginx

启动：/usr/local/nginx/nginx

访问: http://x.x.x.x

出现如下表示nginx安装正常

暂时先关闭nginx，以下是关闭nginx脚本

#!/bin/sh 
# 
# nginx - this script starts and stops the nginx daemin 
# 
# chkconfig:   - 85 15 
# description:  Nginx is an HTTP(S) server, HTTP(S) reverse  
#			   proxy and IMAP/POP3 proxy server 
# processname: nginx 
# config:	  /usr/local/nginx/conf/nginx.conf 
# pidfile:	 /usr/local/nginx/logs/nginx.pid 
 
# Source function library. 
. /etc/rc.d/init.d/functions 
 
# Source networking configuration. 
. /etc/sysconfig/network 
 
# Check that networking is up. 
[ "$NETWORKING" = "no" ] && exit 0 
 
nginx="/usr/local/nginx/nginx" 
prog=$(basename $nginx) 
 
NGINX_CONF_FILE="/usr/local/nginx/nginx.conf" 
 
lockfile=/var/lock/subsys/nginx 
 
start() { 
	[ -x $nginx ] || exit 5 
	[ -f $NGINX_CONF_FILE ] || exit 6 
	echo -n $"Starting $prog: " 
	daemon $nginx -c $NGINX_CONF_FILE 
	retval=$? 
	echo 
	[ $retval -eq 0 ] && touch $lockfile 
	return $retval 
} 
 
stop() { 
	echo -n $"Stopping $prog: " 
	killproc $prog -QUIT 
	retval=$? 
	echo 
	[ $retval -eq 0 ] && rm -f $lockfile 
	return $retval 
} 
 
restart() { 
	configtest || return $? 
	stop 
	start 
} 
 
reload() { 
	configtest || return $? 
	echo -n $"Reloading $prog: " 
	killproc $nginx -HUP 
	RETVAL=$? 
	echo 
} 
 
force_reload() { 
	restart 
} 
 
configtest() { 
  $nginx -t -c $NGINX_CONF_FILE 
} 
 
rh_status() { 
	status $prog 
} 
 
rh_status_q() { 
	rh_status >/dev/null 2>&1 
} 
 
case "$1" in 
	start) 
		rh_status_q && exit 0 
		$1 
		;; 
	stop) 
		rh_status_q || exit 0 
		$1 
		;; 
	restart|configtest) 
		$1 
		;; 
	reload) 
		rh_status_q || exit 7 
		$1 
		;; 
	force-reload) 
		force_reload 
		;; 
	status) 
		rh_status 
		;; 
	condrestart|try-restart) 
		rh_status_q || exit 0 
			;; 
	*) 
		echo $"Usage: $0 {start|stop|status|restart|condrestart|try-restart|reload|force-reload|configtest}" 
		exit 2 
esac

4.安装fcgi及flup

tar zxvf spawn-fcgi-1.6.4.tar.gz

cd spawn-fcgi-1.6.4

./configure

make && make install

tar zxvf flup-1.0.2.tar.gz

cd flup-1.0.2

python setup.py  install

5.配置nginx及webpy应用

vim  /usr/local/nginx/nginx.conf

worker_processes  1;
events {
	worker_connections  1024;
}

http {
	include	   mime.types;
	default_type  application/octet-stream;
	sendfile		on;
	keepalive_timeout  65;
	server {
		listen	   80;
		server_name  localhost;
		root /data/www/;
		access_log  /data/log/test.access.log;


	    location / {
		 include fastcgi_params;
			 fastcgi_param SCRIPT_FILENAME $fastcgi_script_name;  # [1]
			 fastcgi_param PATH_INFO $fastcgi_script_name;		# [2]
		 fastcgi_pass 127.0.0.1:9002;
		}

	   location /static/ {							  #配置静态文件路径访问
		if (-f $request_filename){
			rewrite ^/static/(.*)$ /static/$1 break;
		}
	
	   }

		error_page   500 502 503 504  /50x.html;
		location = /50x.html {
			root   html;
		}
	}
}

web.py应用加上以下内容server.py

if __name__ == "__main__":
　　web.wsgi.runwsgi = lambda func, addr=None: web.wsgi.runfcgi(func, addr)
　　app.run()

同时配置一个启动脚本

[root@roddy www]# vim start.sh 
#!/bin/sh
spawn-fcgi -d /data/www -f /data/www/server.py -a 127.0.0.1 -p 9002

启动fcgi及nginx

[root@roddy www]# sh start.sh 

[root@roddy www]# /etc/init.d/nginx  start

检查监听端口

[root@roddy www]# netstat -nlpt | egrep "9002|80" 
tcp        0      0 127.0.0.1:9002              0.0.0.0:*                   LISTEN      54799/python        
tcp        0      0 0.0.0.0:80                  0.0.0.0:*                   LISTEN      54816/nginx         
[root@roddy www]# 

现在即可输入http://x.x.x.x访问你的应用吧
