内核版本查看Linux英文内核版本号（linux显示英文）
Linux is an open source operating system and is composed of a kernel, system libraries and utilities, and user programs. The kernel is the core of the operating system, responsible for interfacing between user programs and hardware. The kernel also provides support for services like file systems, memory management, and process management.
When you install a Linux operating system, the version of the kernel will be determined by the distribution you are using. The Linux kernel is updated regularly, with bug fixes and new features added. It is important to be aware of which version of the kernel you are running, as this can affect applications, compatibility, and security.
To check the version of the Linux kernel you are running, you can use the command line tool “uname.” This tool prints out the kernel name, version, and release information. The output should look something like this:
[user@hostname]$ uname –a
Linux hostname 3.10.0-957.12.2.el7.x86_64 #1 SMP Tue Feb 19 03:15:02 UTC 2019 x86_64 x86_64 x86_64 GNU/Linux
This output indicates that the kernel version is 3.10.0-957.12.2.el7, which is the numerical version identifier for the Linux kernel. The “el7” in the version identifier indicates that this is a version of the Red Hat Enterprise Linux (RHEL) 7 series of kernels.
You can also use the command “cat /proc/version” to get detailed information about the kernel such as the version, patch level, and build date. The output should look something like this:
[user@hostname]$ cat /proc/version
Linux version 3.10.0-764.11.1.el7.x86_64 (mockbuild@buildhw-09.phx2.fedoraproject.org) (gcc version 4.8.5 20150623 (Red Hat 4.8.5-36) (GCC) ) #1 SMP Thu Mar 7 15:06:02 UTC 2019
In this example, the kernel version is 3.10.0-764.11.1.el7. This indicates that the kernel is a version of the Red Hat Enterprise Linux (RHEL) 7 series of kernels.
You can also view the version of the Linux kernel in the /boot/grub/grub.conf file. The version information is usually at the top of the file. For example, the output might look something like this:
default=0
timeout=5
title Red Hat Enterprise Linux Server (3.10.0-957.12.2.el7.x86_64)
In this example, the kernel version is 3.10.0-957.12.2.el7. This indicates that the kernel is a version of the Red Hat Enterprise Linux (RHEL) 7 series of kernels.
By checking the version of the Linux kernel, you can make sure that you are running the version of the kernel recommended for your system and that you have any available security patches. It can also help you debug problems and get support.
