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
