netstat 查看端口占用语法格式:
netstat -tunlp | grep 端口号
- -t (tcp) 仅显示tcp相关选项
- -u (udp)仅显示udp相关选项
- -n 拒绝显示别名,能显示数字的全部转化为数字
- -l 仅列出在Listen(监听)的服务状态
- -p 显示建立相关链接的程序名

# netstat -tunlp | grep 8000tcp 0 0 0.0.0.0:8000 0.0.0.0:* LISTEN 26993/nodejs
更多命令:
netstat -ntlp //查看当前所有tcp端口 netstat -ntulp | grep 80 //查看所有80端口使用情况 netstat -ntulp | grep 3306 //查看所有3306端口使用情况
