大罗-PHP/Python博客

我的本博客由Dreamhost提供空间. 但部分教育网同学无法访问到或速度极慢.于是产生了一个使用Nginx建立代理服务器 cn.luochunhui.com的想法

设置原理:
用户访问cn.luochunhui.com(上海S1) => S1访问www.luochunhui.com(美国S2) => S2返回内容给S1 => S1返回内容给用户.

设置方法:
增加Nginx配置文件:

#file: /etc/nginx/sites-enabled/cn.luochunhui.com 
server {
	listen   80;
	server_name  cn.luochunhui.com;

	access_log  /var/www/logs/cn.luochunhui.com_access.log;

	location /robots.txt {
		root   /home/rollenc/luochunhui.com;
	}

	location / {
  		proxy_pass http://www.luochunhui.com;
	}

}

其中有一段 关于 robots.txt 的设置. 是关于SEO方面的. 在代理服务器上设置了一个 robots文件, 告诉蜘蛛别爬cn域.

今天搞定了一台Nginx服务器，替代了lighttpd。 记录一下安装
系统： Ubuntu 8.04 Server amd64

1. 安装Nginx及php cgi
sudo apt-get install build-essential nginx php5-common php5-cgi
2. 启用php fastcgi

/etc/nginx/sites-available/default
ref: defaultPHP
==================================

server {
    listen 80;
    client_max_body_size 50M;
    server_name localhost;
    root /var/www/nginx-default;
    access_log  /var/log/nginx/localhost.access.log;
    location / {
      index  index.html index.php;
      expires  max;
      break;
    }
    location ~ \.php$ {
      fastcgi_pass   127.0.0.1:9000;
      fastcgi_index  index.php;
      fastcgi_param  SCRIPT_FILENAME  /var/www/nginx-default$fastcgi_script_name;
      include        /etc/nginx/fastcgi.conf;
      expires  max;
    }
    error_page  500 502 503 504  /50x.html;
    location =  /500.html { root  /var/www/nginx-default; }
}

3. 设置fastcgi参数

/etc/nginx/fastcgi.conf
ref: fastcgi.conf
=========================

fastcgi_param  QUERY_STRING       $query_string;
fastcgi_param  REQUEST_METHOD     $request_method;
fastcgi_param  CONTENT_TYPE       $content_type;
fastcgi_param  CONTENT_LENGTH     $content_length;

4. 建立fastcgi 脚本

/etc/init.d/php-fastcgi
ref: php-fastcgi
=======================

#!/bin/sh
### BEGIN INIT INFO
# Provides:          php-fastcgi
# Required-Start:    $all
# Required-Stop:     $all
# Default-Start:     2 3 4 5
# Default-Stop:      0 1 6

. /lib/lsb/init-functions
if [ "$START" != "yes" -a "$1" != "stop" ]; then
  log_warning_msg "To enable $NAME, edit /etc/default/$NAME and set START=yes"
  exit 0
fi
export PHP_FCGI_CHILDREN PHP_FCGI_MAX_REQUESTS
DAEMON_ARGS="-q -b $FCGI_HOST:$FCGI_PORT"
do_start()
{
  start-stop-daemon --start --quiet --pidfile $PIDFILE --exec $DAEMON --test > /dev/null || return 1
  start-stop-daemon --start --quiet --pidfile $PIDFILE --exec $DAEMON --background --make-pidfile --chuid $EXEC_AS_USER --startas $DAEMON -- $DAEMON_ARGS || return 2
}

do_stop()
{
  start-stop-daemon --stop --quiet --retry=TERM/30/KILL/5 --pidfile $PIDFILE > /dev/null # --name $DAEMON
  RETVAL="$?"
  [ "$RETVAL" = 2 ] && return 2
  start-stop-daemon --stop --quiet --oknodo --retry=0/30/KILL/5 --exec $DAEMON
  [ "$?" = 2 ] && return 2
  rm -f $PIDFILE
  return "$RETVAL"
}

case "$1" in
  start)
    [ "$VERBOSE" != no ] && log_daemon_msg "Starting $DESC" "$NAME"
    do_start
    case "$?" in
      0|1) [ "$VERBOSE" != no ] && log_end_msg 0 ;;
      2) [ "$VERBOSE" != no ] && log_end_msg 1 ;;
    esac
    ;;

    [ "$VERBOSE" != no ] && log_daemon_msg "Stopping $DESC" "$NAME"
    do_stop
    case "$?" in
      0|1) [ "$VERBOSE" != no ] && log_end_msg 0 ;;
      2) [ "$VERBOSE" != no ] && log_end_msg 1 ;;
    esac
    ;;
  restart|force-reload)
    log_daemon_msg "Restarting $DESC" "$NAME"
    do_stop
    case "$?" in
      0|1)
        do_start
        case "$?" in
          0) log_end_msg 0 ;;
          1) log_end_msg 1 ;; # Old process is still running
          *) log_end_msg 1 ;; # Failed to start
        esac
        ;;
      *)
      # Failed to stop
      log_end_msg 1
      ;;
    esac
    ;;
  *)
  echo "Usage: $SCRIPTNAME {start|stop|restart|force-reload}" >&2
  exit 3
  ;;
