Installed version of the image file

CentOS-7-x86_64-DVD-1511

Downloads are available on all major websites.

After the virtual machine is created, put the image file into the VM DVD CD-ROM drive

Turn on the virtual machine

Select Install CentOS 7 for installation

Enter

Select the installation language (the language of the installation process is not the language after the system installation)

Select disk

It is best to install the system with minimum installation and choose the required software package.

At the same time, you can set the machine name and configure the network

When you are finished, click start installation to proceed to the next installation step

Set the password of the administrator root

Choose to restart the system after the installation process is complete

Enter the user and password to log in, and the whole installation process is over.

After logging in, I found that the ifconfig command could not be used, and the result was that the software package net-tools.x86_64 was not installed. Well, it had to be installed by yum install.

After configuring the address and DNS information, you can connect to the network normally. In order to facilitate SSH connection, it is necessary to configure fixed IP.

[root@centos7 ~] # ifconfig

After the address configuration is completed, you can configure the yum source.
