2. 使用ip addr查看要配置的网卡

   cc@ubuntu:~$ ip addr
   1: lo: <LOOPBACK,UP,LOWER_UP> mtu 65536 qdisc noqueue state UNKNOWN group default qlen 1000
       link/loopback 00:00:00:00:00:00 brd 00:00:00:00:00:00
       inet 127.0.0.1/8 scope host lo
          valid_lft forever preferred_lft forever
       inet6 ::1/128 scope host
          valid_lft forever preferred_lft forever
   2: ens33: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc fq_codel state UP group default qlen 1000
       link/ether 00:0c:29:59:f9:bf brd ff:ff:ff:ff:ff:ff
       inet 192.168.93.132/24 brd 192.168.93.255 scope global dynamic ens33
          valid_lft 1688sec preferred_lft 1688sec
       inet6 fe80::20c:29ff:fe59:f9bf/64 scope link
          valid_lft forever preferred_lft forever
   cc@ubuntu:~$
