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
