mac关闭指定端口

先执行如下命令:

lsof -i:端口号

会有类似下面的结果： 

COMMAND     PID       USER   FD   TYPE             DEVICE SIZE/OFF NODE NAME
WebProces 42624 davidzhang    5u  IPv4 0x907152bbf7b2a875      0t0  TCP localhost:64438->localhost:radan-http (ESTABLISHED)
WebProces 42624 davidzhang   10u  IPv4 0x907152bbf7b64a05      0t0  TCP localhost:64439->localhost:radan-http (ESTABLISHED)

然后执行： 

kill -9 42624

结束进程就搞定了
