1. 서론
이번포스팅에서는우분투에서 호스트명과 IP 주소를 변경해보겠습니다.
2. 호스트명 변경
eevee@myserver01:/$ sudo hostnamectl set-hostname myserver02
eevee@myserver01:/$ sudo reboot now
위 실습코드는 기존의 호스트명은 myserver01인데, 이를 myserver02로 바꾸는 코드입니다.
3. IP 주소 변경
이번에는 IP 주소를 변경해보겠습니다. 기존 IP 10.0.2.15에서 
다음과 같이 10.0.2.16으로 변경해보겠습니다.
eevee@myserver02:/$ sudo vim /etc/netplan/00-installer-config.yaml
network:
ethernets:
  enp0s3:
    addresses: [10.0.2.16/8]
