linux端口占用查看

1. lsof -i:端口号 用于查看某一端口的占用情况，比如查看8000端口使用情况，lsof -i:8000

   # lsof -i:8000
   COMMAND   PID USER   FD   TYPE  DEVICE SIZE/OFF NODE NAME
   lwfs    22065 root    6u  IPv4 4395053      0t0  TCP *:irdmi (LISTEN)
   

2. netstat -tunlp | grep 端口号，用于查看指定的端口号的进程情况，如查看8000端口的情况，netstat -tunlp |grep 8000

   # netstat -tunlp
