linux怎么查看服务器硬件信息?
Linux环境下查看服务器硬件信息
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
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 mode
cat /proc/cpuinfo | grep flags | grep ' lm ' | wc -l
查看内存信息
cat /proc/meminfo
