How to view version information under Linux, including the number of digits, version information, CPU kernel information, CPU specific model, and so on, the whole CPU information is clear at a glance.

1. # uname-a (Linux views the current operating system kernel information of the version)

5. # getconf LONG_BIT (Linux view version indicates that CPU is running in 32bit mode, but it does not mean that CPU does not support 64bit)

[hadoop@admin01 ~] $getconf LONG_BIT64

6. # lsb_release-a

[root@Rocky opt] # lsb_release-aLSB Version:: core-4.1-amd64:core-4.1-noarchDistributor ID: CentOSDescription: CentOS Linux release 7.4.1708 (Core) Release: 7.4.1708Codename: Cor

Note: the query version information for the sixth is done on another machine, and if you need to use this command on the local machine to query, you first need to install this command on yum. In order to show it vividly, I personally used the command yum install-y redhat-lsb to install it on the cluster. Because there are more packages downloaded, it will take a little longer.
