The editor consulted all kinds of materials and sorted out simple and easy-to-use methods of operation. I hope it will be helpful to answer the doubts of "what problems need to be paid attention to when installing Centos7?" Next, please follow the editor to study!

What the server does is raid 1.

1. Prepare a U disk of about 8G

2. Download a system from https://www.yisu.com/softs/188482.html. I use CentOS-7.0-1406-x86_64-DVD.iso.

3. Download a CentOS7.0 USB disk recording tool; https://www.yisu.com/softs/511099.html

4. Use the CentOS7.0 USB disk recording tool to burn the downloaded system into the U disk; then, copy the file CentOS-7.0-1406-x86_64-DVD.iso into the root directory of the U disk; the U disk should be larger than 4G

5. Enter the bios configuration interface of the server and set it to usb to start.

6. Insert the burned U disk into the server and restart the system

7. Press Tab when the following interface appears

CentOS 7

Install CentOS7

Test this media & install CentOS 7

Troubleshooting

Press Tab for full configuration options on menu items.

If it goes smoothly, you can install it directly. Please refer to: https://www.yisu.com/os/521868.html

8. If you burn it with UltraISO, maybe at this time, there will be

> vmlinuz initrd=initrd.img inst.stage2=hd:LABEL=CentOS\ x207\ x20x86_64 rd.live.check quiet

The text appears at the bottom of the screen. Change this line of text to

> vmlinuz initrd=initrd.img inst.stage2=hd:/dev/sdc4 quiet

.

Note that the name of the device for each computer's usb is different, mine is in / dev/sdc4. If you are not sure about the device name of your usb, you can change the text to

> vmlinuz initrd=initrd.img linux dd quiet

After you enter, the screen will display an interface of your choice, and you can try it one by one.

9. Then you can install it smoothly.

To sum up, the installation of CentOS7 is much more convenient than the previous version. However, there are some changes in the system.

Note:

1. I installed the system under raid 1. After entering the installation interface, a dialog box appears that prompts "An Unknown Error Has Occurred". The top line of detail info is probably exception "/ usr/lib64/python2.7/site-packages/pyanaconda/bootloader.py". This message appears probably because you have some raid data on your hard drive, which conflicts with the installer. Then I formatted the whole disk with diskgenius. Finally, reinstall, and finally see the interface to choose the language.

At this point, the study on "what problems you need to pay attention to when installing Centos7" is over. I hope to be able to solve your doubts. The collocation of theory and practice can better help you learn, go and try it!
