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
