In this issue, the editor will bring you about how to upgrade the CentOS kernel with yum and support reiserfs. The article is rich in content and analyzes and describes it from a professional point of view. I hope you can get something after reading this article.

The kernel of the CentOS kernel is the most basic part of the operating system. It is part of the software that provides many applications with secure access to computer hardware, which is limited, and the CentOS kernel determines when and how long a program operates on a certain part of the hardware. Operating directly on the hardware is very complex, so the kernel usually provides a hardware abstract way to accomplish these operations.

ReiserFS is a new type of file system that holds data in a different way-a fully balanced tree structure, including file data, file names, and log support. ReiserFS also supports a large number of disks and disk arrays, and can continue to maintain fast search speed and high efficiency.

1. View the CentOS kernel upgrade package

Yum-disablerepo updates,base-enablerepo=centosplus list 'kernel*'

two。 Install the name of the kernel package to upgrade

Yum-disablerepo updates,base-enablerepo=centosplus install kernel.x86_64

3. Install reiserfs tools

Yum-disablerepo updates,base-enablerepo=centosplus install reiserfs-utils.x86_64

4. Create a partition through fdisk

Fdisk / dev/sda

Partprobe

5. Use the mkfs.reiserfs tool to format the partition (N is the number of partitions you just created)

Mkfs.reiserfs / dev/sdaN

In this way, we have finished upgrading the CentOS kernel with yum and making the upgraded CentOS kernel support reiserfs.
