Mac查看占用端口进程

说明

有的时候IDEA Intellij突然闪退了，Tomcat还没在运行，需要用命令行根据端口找出pid，并杀掉进程。

#查看进程
lsof -i tcp:8001
#杀掉进程
kill -9 $PID

举例：

% lsof -i:8001
COMMAND   PID    USER   FD   TYPE             DEVICE SIZE/OFF NODE NAME
java    21574 zgpeace  159u  IPv6 0x90d91a393b5f7de9      0t0  TCP localhost:vcom-tunnel->localhost:49735 (ESTABLISHED)
java    21574 zgpeace  160u  IPv6 0x90d91a393b111569      0t0  TCP *:vcom-tunnel (LISTEN)
java    21574 zgpeace  164u  IPv6 0x90d91a393b5f4ce9      0t0  TCP localhost:vcom-tunnel->localhost:49809 (ESTABLISHED)
java    22375 zgpeace  144u  IPv6 0x90d91a393b5f8409      0t0  TCP localhost:49809->localhost:vcom-tunnel (ESTABLISHED)

% kill -9 21574
