  • Linux下查看CPU型号,内存大小,硬盘空间命令

    1 查看CPU

      1.1 查看CPU个数

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

      2

      **uniq命令:删除重复行;wc –l命令:统计行数**

      1.2 查看CPU核数

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

      cpu cores : 4

      1.3 查看CPU型号

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

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

      总结:该服务器有2个4核CPU,型号Intel(R) Xeon(R) CPU E5630 @ 2.53GHz

    2 查看内存

      2.1 查看内存总数

      #cat /proc/meminfo | grep MemTotal

      MemTotal: 32941268 kB //内存32G

      2.2 查看内存条数
