查看CPU信息（型号）
[file@dell ~]$ cat /proc/cpuinfo | grep name | cut -f2 -d: | uniq -c8 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 -c1 physical id: 01 address sizes : 46 bits physical, 48 bits virtual1 physical id: 11 address sizes : 46 bits physical, 48 bits virtual1 physical id: 01 address sizes : 46 bits physical, 48 bits virtual1 physical id: 11 address sizes : 46 bits physical, 48 bits virtual1 physical id: 01 address sizes : 46 bits physical, 48 bits virtual1 physical id: 11 address sizes : 46 bits physical, 48 bits virtual1 physical id: 01 address sizes : 46 bits physical, 48 bits virtual1 physical id: 11 address sizes : 46 bits physical, 48 bits virtual
查看系统是32位还是64位
[file@dell ~]$ getconf LONG_BIT64
(说明当前CPU运行在64bit模式下)
[file@dell ~]$ cat /proc/cpuinfo | grep flags | grep ' lm ' | wc -l8
(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 -aLinux intimeam 2.6.18-194.el5 #1 SMP Fri Apr 2 14:58:35 EDT i686 i686 i386 GNU/Linux
or
[file@dell ~]$ uname -aLinux dell.product.1 2.6.32-279.el6.x86_64 #1 SMP Fri Jun 22 12:19:21 UTC x86_64 x86_64 x86_64 GNU/Linux
