Linux下查看CPU信息、机器型号等硬件信息

查看CPU信息（型号）

[file@dell ~]$ cat /proc/cpuinfo | grep name | cut -f2 -d: | uniq -c 8 Intel(R) Xeon(R) CPU E5-2609 0 @ 2.40GHz

(看到有8个逻辑CPU, 也知道了CPU型号)

[file@dell ~]$ cat /proc/cpuinfo | grep physical | uniq -c 1 physical id : 0 1 address sizes   : 46 bits physical, 48 bits virtual 1 physical id : 1 1 address sizes   : 46 bits physical, 48 bits virtual 1 physical id : 0 1 address sizes   : 46 bits physical, 48 bits virtual 1 physical id : 1 1 address sizes   : 46 bits physical, 48 bits virtual 1 physical id : 0 1 address sizes   : 46 bits physical, 48 bits virtual 1 physical id : 1 1 address sizes   : 46 bits physical, 48 bits virtual 1 physical id : 0 1 address sizes   : 46 bits physical, 48 bits virtual 1 physical id : 1 1 address sizes   : 46 bits physical, 48 bits virtual

查看系统是32位还是64位

[file@dell ~]$ getconf LONG_BIT 64

(说明当前CPU运行在64bit模式下)

[file@dell ~]$ cat /proc/cpuinfo | grep flags | grep ' lm ' | wc -l 8

(结果大于0, 说明支持64bit计算. lm指long mode, 支持lm则是64bit)

 

使用uname查看

[root@intimeam webserver]# uname -a
Linux intimeam 2.6.18-194.el5 #1 SMP Fri Apr 2 14:58:35 EDT 2010 i686 i686 i386 GNU/Linux

or

[file@dell ~]$ uname -a
Linux dell.product.1 2.6.32-279.el6.x86_64 #1 SMP Fri Jun 22 12:19:21 UTC 2012 x86_64 x86_64 x86_64 GNU/Linux
