1、查看操作系统内核信息

[root@local ~]# uname -a
Linux local 2.6.18-194.el5 #1 SMP Tue Mar 16 21:52:39 EDT 2010 x86_64 x86_64 x86_64 GNU/Linux

2、查询CPU信息

整体信息

[root@local ~]# cat /proc/cpuinfo

CPU名称

[root@local ~]# cat /proc/cpuinfo | grep name
model name      :        Intel(R) Core(TM) i3-2310M CPU @ 2.10GHz
model name      :        Intel(R) Core(TM) i3-2310M CPU @ 2.10GHz
model name      :        Intel(R) Core(TM) i3-2310M CPU @ 2.10GHz
model name      :        Intel(R) Core(TM) i3-2310M CPU @ 2.10GHz

[root@local ~]# cat /proc/cpuinfo | grep name | cut -f2 -d: | uniq -c
      4         Intel(R) Core(TM) i3-2310M CPU @ 2.10GHz

CPU物理个数

[root@local ~]# cat /proc/cpuinfo | grep "physical id" | sort | uniq | wc -l
2

[root@local ~]# cat /proc/cpuinfo | grep physical | uniq -c
      1 physical id     : 0
      1 address sizes   : 40 bits physical, 48 bits virtual
      1 physical id     : 0
      1 address sizes   : 40 bits physical, 48 bits virtual
      1 physical id     : 1
      1 address sizes   : 40 bits physical, 48 bits virtual
      1 physical id     : 1
      1 address sizes   : 40 bits physical, 48 bits virtual

CPU逻辑个数

[root@local ~]# cat /proc/cpuinfo | grep "processor" | wc -l
4

查看CPU运行模式

[root@local ~]# getconf LONG_BIT
64

查看CPU是否支持64位

[root@local ~]# cat /proc/cpuinfo | grep flags | grep ‘ lm ‘ | wc -l
4
(结果大于0, 说明支持64bit计算. lm指long mode, 支持lm则是64bit)

查看CUP主频

[root@local ~]# cat /proc/cpuinfo | grep MHz | uniq
cpu MHz         : 2093.211
