2017년 6월 27일 (화) 01:51 기준 최신판

CentOS 7 ifconfig 명령어 없음
ifconfig: command not found

1 문제상황[ | ]

CentOS 7을 최소설치했더니 ifconfig가 없다.^[1]

[root@zetawiki ~]# ifconfig
-bash: ifconfig: command not found

[root@zetawiki ~]# /sbin/ifconfig
-bash: /sbin/ifconfig: No such file or directory

2 해결방법 1: ip 명령어 사용[ | ]

ifconfig 명령어 대신 ip 명령어를 사용하자.

[root@zetawiki ~]# 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: ens33: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc pfifo_fast state UP qlen 1000
    link/ether 00:0c:29:cb:a9:a7 brd ff:ff:ff:ff:ff:ff
    inet 192.168.245.130/24 brd 192.168.245.255 scope global dynamic ens33
       valid_lft 1786sec preferred_lft 1786sec
    inet6 fe80::20c:29ff:fecb:a9a7/64 scope link 
       valid_lft forever preferred_lft forever

3 해결방법 2: net-tools 설치[ | ]

ifconfig 명령어를 가지고 있는 net-tools 패키지를 설치하자.

[root@zetawiki ~]# yum install net-tools
