Linux Ubuntu系统查看本机服务器端口占用情况

1、查看所有被占用端口：netstat -ntulp

(base) qiang@09230:~$ netstat -ntulp
Active Internet connections (only servers)
Proto Recv-Q Send-Q Local Address           Foreign Address         State       PID/Program name
tcp        0      0 0.0.0.0:80              0.0.0.0:*               LISTEN      -
tcp6       0      0 :::3306                 :::*                    LISTEN      -
tcp6       0      0 :::80                   :::*                    LISTEN      -
tcp6       0      0 :::1314                 :::*                    LISTEN      -
tcp6       0      0 :::33060                :::*                    LISTEN      -
udp        0      0 127.0.0.53:53           0.0.0.0:*                           -
udp        0      0 0.0.0.0:123             0.0.0.0:*                           -
udp6       0      0 ::1:123                 :::*                                -
udp6       0      0 :::123                  :::*                                -
(base) qiang@09230:~$

2、查看某个端口被占用情况：netstat -ntulp | grep 端口号

(base) qiang@09230:~$ netstat -ntulp | grep 3306
tcp6       0      0 :::3306                 :::*                    LISTEN      -
tcp6       0      0 :::33060                :::*                    LISTEN      -
(base) qiang@09230:~$
