CPL文件,又叫控制面板项(Control Panel Item),多保存于系统安装目录的system32文件夹下,它们分别对应着控制面板中的项目,普通用户的访问受到限制。它可由shell32.dll、control.exe打开。此外,你也可以直接在资源管理器中双击调用Open命令打开(实质上调用了shell32.dll)。
CPL文件本质是Windows可执行性文件,但不属于可以直接独立运行的文件,通常由shell32.dll打开。
system32目录里绝大多数cpl文件是Windows系统文件,具有“存档”文件属性,Windows操作系统的文件保护功能保护它们不被篡改。

如:windows防火墙 firewall.cpl

1.假设负载均衡前端端口是80,ECS后端端口也是80,ECS内网IP是:10.11.192.1

Windows系统服务器使用如下命令:

netstat -ano | findstr :80

Linux系统服务器使用如下命令:



netstat -anp|grep :80



查询监控状态的tcp连接:



netstat -ltp|grep :80



 

如果能看到:10.11.192.1:80的监听,或者0.0.0.0:80的监听则说明这部分正常。

2.检查服务器内网防火墙是否放行80端口,可以暂时关闭防火墙进行测试。

Windows系统可以运行输入firewall.cpl 操作关闭

Linux系统可以输入/etc/init.d/iptables stop 关闭

3.如果是4层负载均衡,只要后端端口telnet有响应即可,可以使用telnet 10.11.192.1 80 来测试。如果是7层负载均衡,需要HTTP状态码是200 等代表正常的状态码。检验方法如下:

Windows系统可以直接在ECS内的浏览器输入内网IP测试是否正常,本例是:http://10.11.192.1

Linux系统可以通过curl -I 命令看看状态是否为HTTP/1.1 200 OK,本例是:curl -I 10.11.192.1

OPTIONS
   --verbose , -v
       Tell the user what is going on by being verbose. Especially print some useful information about unconfigured address families.

   --wide , -W
       Do not truncate IP addresses by using output as wide as needed. This is optional for now to not break existing scripts.

   --numeric , -n
       Show numerical addresses instead of trying to determine symbolic host, port or user names.

   --numeric-hosts
       shows numerical host addresses but does not affect the resolution of port or user names.

   --numeric-ports
       shows numerical port numbers but does not affect the resolution of host or user names.

   --numeric-users
       shows numerical user IDs but does not affect the resolution of host or port names.

   --protocol=family , -A
       Specifies the address families (perhaps better described as low level protocols) for which connections are to be shown.
family is a comma (',') separated list of address family keywords like inet, inet6, unix,  ipx,  ax25,
       netrom, econet, and ddp.  This has the same effect as using the --inet|-4, --inet6|-6, --unix|-x, --ipx, --ax25, --netrom, and --ddp options.

       The address family inet (Iv4) includes raw, udp, udplite and tcp protocol sockets.

   -c, --continuous
       This will cause netstat to print the selected information every second continuously.

   -e, --extend
       Display additional information.  Use this option twice for maximum detail.

   -o, --timers
       Include information related to networking timers.

   -p, --program
       Show the PID and name of the program to which each socket belongs.

   -l, --listening
       Show only listening sockets.  (These are omitted by default.)

   -a, --all
       Show both listening and non-listening (for TCP this means established connections) sockets.  With the --interfaces option, show interfaces that are not up

   -F
       Print routing information from the FIB.  (This is the default.)

   -C
       Print routing information from the route cache.

   delay
       Netstat will cycle printing through statistics every delay seconds.



 

kill进程:
上面的命令找到监听端口的进程号,就可以使用taskkill命令来停止进程:

taskkill /F /PID 进程Id

taskkill /F /im 映像名 /T
