一直以來都是在終端執行shell等腳本，那web界面是否也可以這樣，當然也是可以的
本文以centos 6為例安裝配置

1. 安裝spawn-fcgi
   wget https://github.com/lighttpd/spawn-fcgi/archive/spawn-fcgi-1.6.4.zip
   unzip spawn-fcgi-1.6.4.zip && rm spawn-fcgi-1.6.4.zip
   mv spawn-fcgi-spawn-fcgi-1.6.4/ spawn-fcgi
   cd spawn-fcgi/
   ./autogen.sh
   ./configure
   make && make install
2. 安裝fcgiwrap
   yum -y install fcgi fcgi-devel nginx
   wget https://github.com/gnosek/fcgiwrap/archive/1.1.0.zip
   unzip 1.1.0.zip
   rm 1.1.0.zip
   mv fcgiwrap-1.1.0/ fcgiwrap
   cd fcgiwrap/
   autoreconf -i
   ./configure
   make && make install
3. 添加fcgiwrap 啟動腳本
   腳本啟用用戶要和你nginx啟動用戶一致，註意下腳本中路徑及啟動用戶
   vim /etc/init.d/fcgiwrap
   

   #! /bin/bash
   ### BEGIN INIT INFO

   case "$1" in
       start)
           echo -n "Starting $NAME... "
   
           PID=`pidof $NAME`
           if [ ! -z "$PID" ]; then
               echo " $NAME already running"
               exit 1
           fi

           if [ "$?" != 0 ]; then
               echo " failed"
               exit 1
           else
               echo " done"
           fi
       ;;
   
       stop)
           echo -n "Stoping $NAME... "
   
           PID=`pidof $NAME`
           if [ ! -z "$PID" ]; then
               kill `pidof $NAME`
               if [ "$?" != 0 ]; then
                   echo " failed. re-quit"
                   exit 1
               else
                   rm -f $pid
                   echo " done"
               fi
           else
               echo "$NAME is not running."
               exit 1
           fi
       ;;
   
       status)
           PID=`pidof $NAME`
           if [ ! -z "$PID" ]; then
               echo "$NAME (pid $PID) is running..."
           else
               echo "$NAME is stopped"
               exit 0

       ;;
   
       restart)
           $SCRIPTNAME stop
           sleep 1
           $SCRIPTNAME start
       ;;
   
       *)
           echo "Usage: $SCRIPTNAME {start|stop|restart|status}"
           exit 1
       ;;
   esac

   fcgiwrap

   chmod +x /etc/init.d/fcgiwrap

4. 啟動
   chkconfig --add fcgiwrap
   chkconfig --level 2345 fcgiwrap on
   ./etc/init.d/fcgiwrap restart
5. nginx配置
   測試環境編輯/etc/nginx/conf.d/default.conf，添加
   

       location ~ ^/cgi-bin/cgi/.*\.(cgi|sh) {  #這裏的後綴匹配根據需要修改，可以使用統一cgi後綴
           gzip off;
           fastcgi_pass unix:/tmp/fcgiwrap.socket;
           fastcgi_index index.cgi;
           include fastcgi_params;
           fastcgi_param  SCRIPT_NAME $document_root$fastcgi_script_name;
       }

   重啟nginx：
   nginx -s reload
   mkdir -p /usr/share/nginx/html/cgi-bin 放置首頁html
   mkdir -p /usr/share/nginx/html/cgi-bin/cgi 放置腳本

6. 腳本測試
   vim /usr/share/nginx/html/cgi-bin/cgi/disk.cgi
   

   #!/bin/bash
   echo "Content-Type:text/html;charset=utf-8"
   echo "" 
   #前3行必須是這個格式，html代碼使用echo，linux命令和腳本語法一樣
   
   echo ‘<div style="padding-left:10px;">‘
   echo ‘<h1 style="color:red;border-left:4px solid;padding:4px;">硬盤使用情況</h1>‘
   echo ‘<h5>‘
   dd=`date`
   echo "統計時間: $dd"
   echo ‘</h5>‘
   echo ‘<pre style="border-left: 4px solid rgb(12, 40, 245);padding:5px">‘
   df -hT
   echo ‘</pre>‘
