Some of the issues you may encounter upon installing of CentOS 7 with minimal installation, are running some commands that in the older version of CentOS exist but not in this one. Like a command running “ifconfig” this will prompt you a message as:
[root@server1 ~] # ifconfig - bash : ifconfig : command not found
An alternate command to use instead of ifconfig are “ip addr” or “ip addr sh”
In order for you to have it, you need to search for a packages that provides a certain utility like ifconfig.
You can do “yum provides utility-name” so in our case we do:
[root@server1 ~]# yum provides ifconfig Loaded plugins: fastestmirror Loading mirror speeds from cached hostfile * base: centos.uhost.hk * extras: centos.communilink.net * updates: centos.uhost.hk net-tools-2.0-0.17.20131004git.el7.x86_64 : Basic networking tools Repo : @base
So you can install the net-tools to use that deprecated utility.
[root@server1 ~]# yum -y install net-tools
You should be able to use ifconfig command after the installation.
