Linux下如何查看版本信息
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。一些常用的 Linux 命令
1、# uname -a (Linux查看版本当前操作系统内核信息)
[hadoop@admin01 ~]$ uname -a
Linux admin01 2.6.32-358.el6.x86_64 #1 SMP Fri Feb 22 00:31:26 UTC 2013 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)
[hadoop@admin01 ~]$ cat /proc/version
Linux version 2.6.32-358.el6.x86_64 (mockbuild@c6b8.bsys.dev.centos.org) (gcc version 4.4.7 20120313 (Red Hat 4.4.7-3) (GCC) ) #1 SMP Fri Feb 22 00:31:26 UTC 2013
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)
[hadoop@admin01 ~]$ cat /etc/issue
CentOS release 6.4 (Final)
Kernel \r on an \m
[hadoop@admin01 ~]$ cat /etc/redhat-release
CentOS release 6.4 (Final)
4、# cat /proc/cpuinfo (Linux查看cpu相关信息,包括型号、主频、内核信息等)
[hadoop@admin01 ~]$ cat /proc/cpuinfo

5、# getconf LONG_BIT (Linux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)
[hadoop@admin01 ~]$ getconf LONG_BIT
64
6、# lsb_release -a (查询系统版本)
[root@Rocky opt]# lsb_release -a

注释:第6个的查询版本信息是在另一台机器上做的,如果需要在本地的机器使用此命令进行查询的话,首先需要yum安装此命令。为了形象的展现出来,所以我个人在集群上使用命令 yum install -y redhat-lsb 进行了一个安装,因为这个下载的包比较多,所以需要时间会稍微久一点。
