Centos7 Installation Steps and Precautions

I recently purchased a new server, and most of the current servers do not have an optical drive. This time, I installed the system using USB.
server is set up as raid 1.

1Prepare a8G左右的u盘；

2At http://mirrors.163.com/centos/7/isos/x86_64/　 Download a system, I use CentOS-7.0-1406-x86_64-DVD.iso;

3Download a trial version of UltraISO;

4Use UltraISO to burn the downloaded system into the USB flash drive; then, copy CentOS-7.0-1406-x86_64-Also copy the file DVD.iso into the root directory of the USB flash drive; if the space on your USB flash drive is not enough, you can delete all the files in the 'Packages' directory;

5Enter the BIOS setup interface of the server and set it to USB boot;

6Insert the burned USB flash drive into the server, restart the system;

7At this time, when the following interface appears, press Tab,　　

        CentOS 7
Install CentOS7
Test this media & install CentOS 7
Troubleshooting
Press Tab for full configuration options on menu items.

8At 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, and modify this line of text to

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

Note that the device name of usb varies from computer to computer. 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 pressing Enter, the screen will display an interface for you to choose from, and you can try each one individually.

9Next, you can install it smoothly.

Summary, CentOS7The installation is much more convenient than the installation of previous versions. However, the system has also changed some.

Precautions

1、我在raid 1Install the system, and after entering the installation interface, a dialog box appeared, prompting 'An Unknown Error Has Occurred', the line at the top of detail info is probably indicating exception "/usr/lib64/python2.7/site-packages/pyanaconda/bootloader.py. This message appears because there may be some raid data in your hard disk that conflicts with the installation program. Next, I formatted the entire disk with diskgenius. Finally, after reinstallation, I finally saw the language selection interface.
