1)查看网卡  ifconfig

[root@promote ~]# ifconfig

        inet 172.20.46.43  netmask 255.255.255.0  broadcast 172.20.46.255
        inet6 fe80::20c:29ff:fe7e:2885  prefixlen 64  scopeid 0x20<link>
        ether 00:0c:29:7e:28:85  txqueuelen 1000  (Ethernet)
        RX packets 8384  bytes 818361 (799.1 KiB)
