本文介绍了如何在Linux系统中查看各种关键信息，包括操作系统内核版本、操作系统版本、发行版信息、CPU运行模式以及详细的CPU信息。通过一系列命令，如uname-a、cat/proc/version、cat/etc/issue、cat/etc/redhat-release、getconfLONG_BIT和cat/proc/cpuinfo，读者可以全面了解其Linux系统的配置和状态。

查看版本当前操作系统内核信息
[root@node00 ~]# uname -a Linux node00 3.10.0-693.el7.x86_64 #1 SMP Tue Aug 22 21:09:27 UTC 2017 x86_64 x86_64 x86_64 GNU/Linux -
查看当前操作系统版本信息
[root@node00 ~]# cat /proc/version Linux version 3.10.0-693.el7.x86_64 (builder@kbuilder.dev.centos.org) (gcc version 4.8.5 20150623 (Red Hat 4.8.5-16) (GCC) ) #1 SMP Tue Aug 22 21:09:27 UTC 2017 [root@node00 ~]# -
查看版本当前操作系统发行版信息

查看版本说明当前CPU运行在32bit模式下， 但不代表CPU不支持64bit
[root@node00 ~]# getconf LONG_BIT 64 -
查看cpu相关信息，包括型号、主频、内核信息等
