Centos ifconfig installation tutorial, centosifconfig tutorial

Always use the ifconfig command to view network connections in CentOS, including IP addresses, MAC addresses, and network connection status. After upgrading to CentOS 7, ifconfig cannot be found. Previously, this command has been deprecated and switched to the ip address command. The same thing happened in RHEL 7, Oracle Linux 7, and Scientific Linux 7 minimal versions.

In CentOS 7 minimal system, you can use "ip addr" and "ip link" to view network connections and their statuses, and use "ip-s link" to view statistics.

If you still want to use ifconfig, you need to install it yourself. First, you must know which package provides the ifconfig command,

Yum provides ifconfig

Or,

Yum whatprovides ifconfig

You can find the corresponding software package net-tools and install it,

Yum install net-tools

After installation, you can use ifconfig-a to view the network status.

Of course, this method can also be used to query other installation packages that want to use but cannot find the corresponding commands.
