linux 7 을 최소 설치 하게되면 이런저런 tool 이 설치되지 않아 불편한 점이 많다
우선 기존에 먹히던 ‘ifconfig’ 로 network 를 확인 할 수 없습니다.
ifconfig
-bash: ifconfig: command not found
그럴땐 다른 명령어로 우선 network 를 확인한다
——————————————————————————–
[root@localhost ~]# ip addr list
1: lo: <LOOPBACK,UP,LOWER_UP> mtu 65536 qdisc noqueue state UNKNOWN

그리고 yum install 로 net-tools 를 설치해 줘야 합니다.

[root@localhost ~]# yum install -y net-tools

이제 ifconfig 로 확인이 가능하다.

확인결과 linux 7.4 부터는 최소설치를 해도 net-tools 를 설치하지 않아도 ifconfig 로 ip 확인이 가능하다.
