Linux环境下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 
      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 mode
      cat /proc/cpuinfo | grep flags | grep ' lm ' | wc -l
      16
