MAC OS查看端口占用情况及杀死进程

终端命令

sudo lsof -i tcp:8889

COMMAND PID USER FD TYPE DEVICE SIZE/OFF NODE NAME
node 1519 xinchanghao 13u IPv4 0x67d5fd84c3f59e4f 0t0 TCP localhost:ddi-tcp-2->localhost:63590 (CLOSE_WAIT)
node 1519 xinchanghao 14u IPv4 0x67d5fd84c2ddcc5f 0t0 TCP *:ddi-tcp-2 (LISTEN)

然后根据PID杀进程:

sudo kill -9 1519
