6. service network restart 명령어를 이용해 네트워크 서비스를 재시작합니다. 여기서는 service network restart 명령어를 사용했지만, CentOS 7에서는 systemctl restart network. service 명령어로도 재시작할 수 있습니다.

[root@centos network-scripts]# service network restart
Restarting network (via systemctl):                        [  OK  ]

7. 이번에는 ifconfig 명령어를 이용해 enp0s8의 IP가 잘 설정되어 있는 것을 확인합니다.
