查看CPU型号cat /proc/cpuinfo | grep name | cut -f2 -d: | uniq -c

16 Intel (R) Xeon(R) CPU X5560 @ 2.80GHz

查看物理CPU个数cat /proc/cpuinfo | grep physical | uniq -c

1 physical id : 1

1 physical id : 0

查看CPU运行模式 32位或者64位如果是32位的话并不代表不能运行在64位下getconf LONG_BIT

64

查看是否CPU支持64位系统如果值大于0则支持64位运算 lm指long modecat /proc/cpuinfo | grep flags | grep ' lm ' | wc -l
