Windows如何查看端口占用情况
方法1. cmd命令行执行netstat命令，查看端口占用情况
netstat -ano
以上命令输出太多信息，不方便查看，通过如下命令搜索具体端口占用情况，例如：8080端口
netstat -ano | findstr "8080"
方法2. 打开资源监视器
按下Win + R键，输入resmon ，回车，打开资源监视器，点击网络，查看侦听端口
另外：
如果需要终止某个进程，使用taskkill命令，查看命令帮助
C:\Users\Administrator>taskkill /?TASKKILL [/S system [/U username [/P [password]]]]{ [/FI filter] [/PID processid | /IM imagename] } [/T] [/F]Description:This tool is used to terminate tasks by process id (PID) or image name.Parameter List:/S system Specifies the remote system to connect to./U [domain\]user Specifies the user context under which thecommand should execute./P [password] Specifies the password for the given usercontext. Prompts for input if omitted./FI filter Applies a filter to select a set of tasks.Allows "*" to be used. ex. imagename eq acme*/PID processid Specifies the PID of the process to be terminated.Use TaskList to get the PID./IM imagename Specifies the image name of the processto be terminated. Wildcard '*' can be usedto specify all tasks or image names./T Terminates the specified process and anychild processes which were started by it./F Specifies to forcefully terminate the process(es)./? Displays this help message.Filters:Filter Name Valid Operators Valid Value(s)----------- --------------- -------------------------STATUS eq, ne RUNNING |NOT RESPONDING | UNKNOWNIMAGENAME eq, ne Image namePID eq, ne, gt, lt, ge, le PID valueSESSION eq, ne, gt, lt, ge, le Session number.CPUTIME eq, ne, gt, lt, ge, le CPU time in the formatof hh:mm:ss.hh - hours,mm - minutes, ss - secondsMEMUSAGE eq, ne, gt, lt, ge, le Memory usage in KBUSERNAME eq, ne User name in [domain\]userformatMODULES eq, ne DLL nameSERVICES eq, ne Service nameWINDOWTITLE eq, ne Window titleNOTE----1) Wildcard '*' for /IM switch is accepted only when a filter is applied.2) Termination of remote processes will always be done forcefully (/F).3) "WINDOWTITLE" and "STATUS" filters are not considered when a remotemachine is specified.Examples:TASKKILL /IM notepad.exeTASKKILL /PID 1230 /PID 1241 /PID 1253 /TTASKKILL /F /IM cmd.exe /TTASKKILL /F /FI "PID ge 1000" /FI "WINDOWTITLE ne untitle*"TASKKILL /F /FI "USERNAME eq NT AUTHORITY\SYSTEM" /IM notepad.exeTASKKILL /S system /U domain\username /FI "USERNAME ne NT*" /IM *TASKKILL /S system /U username /P password /FI "IMAGENAME eq note*"例如，终止占用8080端口的7216进程，命令如下：
taskkill /f /t /pid 7216参数含义：
/f：强制终止进程
/t：终止所有子进程
/pid：根据进程id终止进程
终止使用8080端口的进程
C:\Users\Administrator>taskkill /f /t /pid 7216
SUCCESS: The process with PID 7216 (child process of PID 11896) has been terminated.再次查看8080端口的占用情况
C:\Users\Administrator>netstat -ano | findstr "8080"C:\Users\Administrator>完成！enjoy it!
