  • Linux 系统查看硬件配置信息（转载）

    一、查看主板
    查看主板型号

    Code example:
    dmidecode -t baseboard
    SMBIOS 2.4 present.
     
    Handle 0x0002, DMItype 2, 8 bytes
    Base Board Information
            Manufacturer: Gigabyte Technology Co., Ltd.
            Product Name: G41MT-D3   #这是我的主板型号啦
            Version:
            Serial Number:

    查看BIOS信息

    Code example:
    dmidecode -t bios
    ......
    BIOS Information
        Vendor: American Megatrends Inc.
        Version: 4.6.5
        Release Date: 04/25/2012
        .......
        BIOS Revision: 4.6
    ......

    二、查看CPU
    通过lscpu命令查看

    Code example:
    lscpu
    Architecture:          x86_64
    CPU op-mode(s):        32-bit, 64-bit
    CPU(s):                1
    Thread(s) per core:    1
    Core(s) per socket:    1
    CPU socket(s):         1
    NUMA node(s):          1
    Vendor ID:             GenuineIntel
    CPU family:            15
    Model:                 4
    Stepping:              9
    CPU MHz:               2800.135
    L1d cache:             16K
    L2 cache:              256K

    查看/proc/cpuinfo文件，获取CPU详细参数。

    Code example:
    cat /proc/cpuinfo
    processor       : 0
    vendor_id       : GenuineIntel
    cpu family      : 15
    model           : 4
    model name      : Intel(R) Celeron(R) CPU 2.80GHz  #CPU型号
    stepping        : 9
    cpu MHz         : 2800.135
    cache size      : 256 KB
    fpu             :yes
    fpu_exception   :yes
    cpuid level     : 5
    wp              :yes
    flags           : fpu vme de pse tsc msr pae mce...
    bogomips        : 5600.27
    clflush size    : 64
    cache_alignment : 128
    address sizes   : 36 bits physical, 48 bits virtual
    power management:

    三、查看内存
    内存使用情况

    Code example:
    free -m
                 total       used      free     shared    buffers     cached
    Mem:          1977       1254        722          0        150        564
    -/+ buffers/cache:        539       1438
    Swap:         3858          0       3858

    内存硬件信息

    Code example:
    dmidecode -t memory
    SMBIOS 2.7 present.
     
    Handle 0x0008, DMItype 16, 23 bytes
    Physical Memory Array
        Location: System Board Or Motherboard
    ....
        Maximum Capacity: 32 GB
    ....
     
    Handle 0x000A, DMItype 17, 34 bytes
    ....
    Memory Device
        Array Handle: 0x0008
        Error Information Handle: Not Provided
        Total Width: 64 bits
        Data Width: 64 bits
        Size: 4096 MB
    .....

    四、查看网卡
    网卡型号

    Code example:
    lspci|grep-i 'eth'
    02:00.0 Ethernet controller: Realtek Semiconductor Co., Ltd. RTL8111/8168BPCI Express Gigabit Ethernet controller (rev 06)

    参数和指标

    Code example:
    ethtooleth0
    Settings foreth0:
        Supported ports: [ TP MII ]
        Supported link modes:   10baseT/Half10baseT/Full
    baseT/Half100baseT/Full
    baseT/Half1000baseT/Full
        Supported pause frame use: No
        Supports auto-negotiation: Yes
        Advertised link modes:  10baseT/Half10baseT/Full
    baseT/Half100baseT/Full
    baseT/Half1000baseT/Full
        Advertised pause frame use: Symmetric Receive-only
        Advertised auto-negotiation: Yes
        Link partner advertised link modes:  10baseT/Half10baseT/Full

        .....
        Speed: 100Mb/s
        Duplex: Full
        .....
        Link detected:yes

    五、查看硬盘
    挂载和使用情况

    Code example:
    df -h
    Filesystem            Size  Used Avail Use% Mounted on
    /dev/sda1            323M  148M  159M  49% /
    tmpfs                 989M     0  989M   0%/lib/init/rw
    udev                  984M  172K  984M   1%/dev
    tmpfs                 989M     0  989M   0%/dev/shm
    /dev/sda9            444G   62G  360G  15% /home
    /dev/sda8            368M   11M  339M   3% /tmp
    /dev/sda5            8.3G  1.5G  6.5G  19% /usr
    /dev/sda6            2.8G  551M  2.1G  21% /var

    分区详细信息

    Code example:
    fdisk -l
     
    Disk /dev/sda: 500.1 GB, 500107862016 bytes
    255 heads, 63 sectors/track, 60801 cylinders
    Units = cylinders of 16065 * 512 = 8225280 bytes
    Sector size (logical/physical): 512 bytes / 512 bytes
    I/Osize (minimum/optimal): 512 bytes / 512 bytes
    Disk identifier: 0x0001ef9d
     
       Device Boot      Start         End      Blocks   Id  System
    /dev/sda1  *           1          43      340992   83  Linux
    Partition 1 does not end on cylinder boundary.
    /dev/sda2             43       60802   488042497    5  Extended
    /dev/sda5             43        1137     8787968   83  Linux
    /dev/sda6           1137        1502     2928640   83  Linux
    /dev/sda7           1502        1994     3951616   82  Linux swap / Solaris
    /dev/sda8           1994        2043      389120   83  Linux
    /dev/sda9           2043       60802   471981056   83  Linux
