Core installation and configuration of CentOS-7.0

I saw a variety of errors in installing CentOS-7.0 in the post bar before, I will write this centos 7 installation tutorial for beginners to refer.

We have two ways to install centos: boot through a CD and boot through a USB flash disk.

If you need to set the CD-ROM drive to the highest priority with a CD,

The USB flash drive sets the removable devices priority to the highest.

Note: After installation, remember to set hard drive to the maximum. If you still choose to enable the system to read the mobile device first, the system will read the device first when you connect to the mobile hard disk or the USB flash disk to restart the machine, causing the computer to fail to start normally.

I have installed windows before.

This interface

For the first (Date & time) time zone, we need to adjust it to our zone, which is generally Asia-China-Shanghai.

The second (keyboard) keyboard language is generally the default

The third operating language (Language Support) is generally the default English language.

The fourth (installation source) is the installation resource. Select the default value.

The fifth (software selection) software selection. By default, the installation is minimized and can be adjusted as needed. However, the installation is usually minimized by default. Then we can install the software as needed.

The sixth installation path (installation destination) must be set by yourself. Otherwise, you cannot enter the begin install

In this interface, we need to set the partition to standard partition and then add three mount points swap,/data ,/, the size is 2048 (SWAp is generally set to twice the memory size), 2048 (this data is set by yourself), and the remaining size is left to the root. For more information, see
