How to Install ifconfig and netstat on RHEL 7.0/CentOS 7.0/Oracle Linux 7

Question :
I have just setup on RHEL 7.0/CentOS 7.0/Oracle Linux 7 minimal server installation but i notice ifconfig and netstat command not found. How to make those command available ?

Solution :
By default, ifconfig and netstat utility is not installed on RHEL 7.0/CentOS 7.0/Oracle Linux 7 minimal server installation. You need to install net-tools utility manually, this include ifconfig and netstat command.

# ifconfig
-bash: ifconfig: command not found

1. Run installation command :

# yum install net-tools -y
