Method steps of how to view version information under Linux

How to view version information under Linux, including digits, version information, CPU kernel information, CPU specific model, etc., the whole CPU information is clear.

1, # uname-a (Linux view version current operating system kernel information)

Linux localhost.localdomain 2.4.20-8 #1 Thu Mar 13 17:54:28 EST 2003 i686 athlon i386 GNU/Linux

2. # cat/proc/version (Linux View Current Operating System Version Information)

5. # getconf LONG_BIT (Linux View Version Note that CPU currently runs in 32bit mode, but does not mean that CPU does not support 64bit)

[hadoop@admin01 ~]$ getconf LONG_BIT
64

6, # lsb_release-a

[root@Rocky opt]# lsb_release -a
LSB Version:  :core-4.1-amd64:core-4.1-noarch
Distributor ID: CentOS
Description:  CentOS Linux release 7.4.1708 (Core) 
Release:  7.4.1708
Codename:  Cor

Note: The query version information of the sixth one is done on another machine. If you need to use this command to query on the local machine, you need yum to install this command first. In order to show the image, I personally used the command yum install-y redhat-lsb to install one on the cluster. Because there are many downloads, it will take a little longer.
