How to view the command linux in the cluster kernel node? in view of this problem, this article introduces the corresponding analysis and solution in detail, hoping to help more partners who want to solve this problem to find a more simple and feasible method.

What does the cluster kernel node view command linux do? The command to view the Linux kernel version can be used in two ways:

First kind

Cat / proc/version [root@S-CentOS home] # cat / proc/versionLinux version 2.6.32-431.el6.x86_64 (mockbuild@c6b8.bsys.dev.centos.org) (gcc version 4.4.7 20120313 (Red Hat 4.4.7-4) (GCC)) # 1 SMP Fri Nov 22 03:15:09 UTC 2013

The second kind

Uname-a [root@S-CentOS home] # uname-aLinux S-CentOS 2.6.32-431.el6.x86_64 # 1 SMP Fri Nov 22 03:15:09 UTC 2013 x86 "64 GNU/Linux

In docker, for example, the underlying core technology includes Libcontainer (LXC), a kernel virtualization technology that provides lightweight virtualization to isolate processes and resources. The two major components of LXC include namespaces and control groups.

Namespaces is a powerful feature of the Linux kernel. Each container has its own namespace, and the applications running in it are as if they were running in a separate operating system. Namespaces ensure that containers do not affect each other, including PID resource isolation, network isolation, IPC resource isolation, file directory isolation, hostname and domain name isolation, user and group isolation.

The control group (cgroups) is mainly used to isolate, restrict, audit and so on shared resources. Only by controlling the resources allocated to the container can we avoid the competition for system resources when multiple containers are running at the same time. You can manage and control the resources such as CPU, memory and network used by the container.

This is the answer to the question about how the cluster kernel node views the command linux. I hope the above content can be of some help to you. If you still have a lot of doubts to be solved, you can follow the industry information channel for more related knowledge.
