查看Linux版本系统信息方法汇总

Linux下如何查看版本信息， 包括位数、版本信息以及CPU内核信息、CPU具体型号等等，整个CPU信息一目了然。
1、# uname －a   （Linux查看版本当前操作系统内核信息）
[songzitea@localhost ~]$ uname -a
Linux localhost.localdomain 2.6.32-642.1.1.el6.x86_64 #1 SMP Tue May 31 21:57:07 UTC 2016 x86_64 x86_64 x86_64 GNU/Linux
2、# cat /proc/version （Linux查看当前操作系统版本信息）
[songzitea@localhost ~]$ cat /proc/version
Linux version 2.6.32-642.1.1.el6.x86_64 (mockbuild@worker1.bsys.centos.org) (gcc version 4.4.7 20120313 (Red Hat 4.4.7-17) (GCC) ) #1 SMP Tue May 31 21:57:07 UTC 2016
3、# cat /etc/issue  或cat /etc/redhat-release（Linux查看版本当前操作系统发行版信息）[songzitea@localhost ~]$ cat /etc/issue
CentOS release 6.8 (Final)
Kernel \r on an \m
4、# cat /proc/cpuinfo （Linux查看cpu相关信息，包括型号、主频、内核信息等）[songzitea@localhost ~]$ cat /proc/cpuinfo
