    原文地址:http://hi.baidu.com/xolee/blog/item/7ddc7524f5379620c9955977.html

    1, 主板信息
      .查看主板的序列号
      --------------------------------------------------
      #使用命令
      dmidecode | grep -i 'serial number'
      #查看板卡信息
      cat /proc/pci
      --------------------------------------------------
      2, cpu信息
      --------------------------------------------------
      #通过/proc文件系统
      1) cat /proc/cpuinfo
      #通过查看开机信息
      2) dmesg | grep -i 'cpu'
      #
      3)dmidecode -t processor

    一、CPU大小
    [root@idc ~]# cat /proc/cpuinfo |grep "model name" && cat /proc/cpuinfo |grep "physical id"
    model name: Intel(R) Xeon(TM) CPU 2.80GHz
    model name: Intel(R) Xeon(TM) CPU 2.80GHz
    model name: Intel(R) Xeon(TM) CPU 2.80GHz
    model name: Intel(R) Xeon(TM) CPU 2.80GHz
    physical id    : 0
    physical id    : 0
    physical id    : 3
    physical id    : 3
    [root@idc ~]#

    说明:Linux下可以在/proc/cpuinfo中看到每个cpu的详细信息。但是对于双核的cpu,在cpuinfo中会看到两个cpu。常常会让人误以为是两个单核的cpu。

    其实应该通过Physical Processor ID来区分单核和双核。而Physical Processor ID可以从cpuinfo或者dmesg中找到.
    flags 如果有 ht 说明支持超线程技术
    判断物理CPU的个数可以查看physical id 的值,相同则为同一个物理CPU

    可以看到上面,这台机器有两个双核的CPU,ID分别是0和3,大小是2.8G。

    二、内存大小
    [root@xbidc ~]# cat /proc/meminfo |grep MemTotal
    MemTotal:              1034612 kB
    [root@xbidc ~]# 
    三、硬盘大小
    [root@xbidc ~]# fdisk -l |grep Disk
    Disk /dev/sda: 300.0 GB, 300000000000 bytes


      --------------------------------------------------
      3, 硬盘信息
      --------------------------------------------------
      #查看分区情况
      fdisk -l
      #查看大小情况
      df -h
      #查看使用情况
      du -h
      #
      hdparm -I /dev/sda
      #
      dmesg | grep sda
      --------------------------------------------------
      4, 内存信息
      --------------------------------------------------
      1) cat /proc/meminfo
      2) dmesg | grep mem
      3) free -m
      4) vmstat
      5) dmidecode | grep -i mem
      --------------------------------------------------
      5, 网卡信息
      --------------------------------------------------
      1) dmesg | grep -i 'eth'
      2) cat /etc/sysconfig/hwconf | grep -i eth
      3) lspci | grep -i 'eth'
      --------------------------------------------------
      6, 鼠标键盘和USB信息
      查看键盘和鼠标:cat /proc/bus/input/devices
      查看USB设备:cat /proc/bus/usb/devices
      查看各设备的中断请求(IRQ):cat /proc/interrupts
      7, 显卡信息
      --------------------------------------------------
      1)lspci |grep -i 'VGA'
      2)dmesg | grep -i 'VGA'
      --------------------------------------------------
      8, 声卡信息
      --------------------------------------------------
      1)lspci |grep -i 'VGA'
      2)dmesg | grep -i 'VGA'
      --------------------------------------------------
      7, 其他命令
      .用硬件检测程序kuduz探测新硬件:service kudzu start ( or restart)
      .dmesg (查看所有启动时检测到的硬件信息)
      .lspci (显示外设信息, 如usb,网卡等信息)
      .cat /etc/sysconfig/hwconf
      .mpstat
      8, 需要手动安装的工具
      lshw,hwinfo,hal-device-manager
      9, Solaris如何检测硬件参数
      俺从别处发现了些有意思的东西:
      Solaris的硬件相关命令
      发表:2004-3-8 11:20:36 出处:你的博客网(yourblog.org)
      --------------------------------------------------------------------------------
      1).查看当前处理器的类型和速度(主频)
