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
