Linux下查看CPU型號,內存大小,硬盤空間命令

   1 查看CPU

  1.1 查看CPU個數

  # cat /proc/cpuinfo | grep "physical id" | uniq | wc -l

  2

  **uniq命令:刪除重復行;wc –l命令:統計行數**

  1.2 查看CPU核數

  # cat /proc/cpuinfo | grep "cpu cores" | uniq

  cpu cores : 4

  1.3 查看CPU型號

  # cat /proc/cpuinfo | grep 'model name' |uniq

  model name : Intel(R) Xeon(R) CPU E5630 @ 2.53GHz

  總結:該服務器有2個4核CPU,型號Intel(R) Xeon(R) CPU E5630 @ 2.53GHz

  2 查看內存

  2.1 查看內存總數

  #cat /proc/meminfo | grep MemTotal

  MemTotal: 32941268 kB //內存32G

  2.2 查看內存條數
