mac 强制关闭指定端口

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
