Comment regler -bash: ifconfig: command not found dans Centos 7

Si vous avez installé CentOS 7 minimal, vous pourriez voir message d’erreur si vous essayez d’utiliser ifconfig pour voir votre adresse IP:

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

Si vous cherchez l’exécutable, il est dans le paquet net-tools

[root@localhost ~]# yum search ifconfig

Au cas où vous ne voulez pas installer le paquet supplémentaire et simplement de voir votre adresse IP, vous pouvez utiliser la commande ip addr

[root@localhost ~]# ip addr

    link/loopback 00:00:00:00:00:00 brd 00:00:00:00:00:00
    inet 127.0.0.1/8 scope host lo

    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:eb:6b:89 brd ff:ff:ff:ff:ff:ff
