새로 설치한다면 VirtualBox에 CentOS 7 설치 참고하여 설치하면 eth0로 나옴
이미 설치했다면 아래 내용 참조

2 문제상황[ | ]

Console

Copy

[root@localhost ~]# ip addr
1: lo <LOOPBACK, UP, LOWER_UP> mtu 65536 qdisc noqueue state UNKNOWN
      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: enp0s3: <BROADCAST<MULTICAST,UP,LOWER_UP> mtu 1500 qdisc pfifo_fast state UP qlen 1000
      link/ether 08:00:27:11:e6:3a brd ff:ff:ff:ff:ff:ff

→ eth0은 없고 enp0s3이 있음
