Linux系统查看服务器硬件信息

1、查看服务器型号

[root@localhost ~]# dmidecode | grep "Product"
        Product Name: RH2288H V3
        Product Name: BC11H****

2、查看服务器的序列号

[root@localhost ~]# dmidecode -t system | grep 'Serial Number'
        Serial Number: 2102311QGG10********

3、统一查看服务器SN序列号和型号

[root@localhost ~]# dmidecode | grep "System Information" -A9 | egrep "Manufacturer|Product|Serial"
        Manufacturer: Huawei
        Product Name: RH2288H V3
        Serial Number: 2102311QGG10********

4、查看CPU信息

备注：两种方法lscpu可以查看CPU的完整信息或者cat /proc/cpuinfo

[root@localhost ~]# lscpu

5、查看GPU显卡信息

通过$ nvidia-smi -q 查看BUS-ID和显卡的序列号之间的对应关系

[root@localhost ~]#  nvidia-smi -q

==============NVSMI LOG==============

        Current                           : N/A
        Pending                           : N/A
**************************************

信息很多，再往下拉可以看到显卡的BUS-ID 信息和相对应的序列号（Serial Number）。那这张显卡插在哪个PCIE卡槽？

通过dmidecode -t slot 查看BUS-ID （BUS Address）和卡槽的对应关系：

[root@localhost ~]# dmidecode -t slot
# dmidecode 3.2
Getting SMBIOS data from sysfs.
SMBIOS 3.3.0 present.
# SMBIOS implementations newer than version 3.2.0 are not
# fully supported by this version of dmidecode.

Handle 0x0025, DMI type 9, 17 bytes
System Slot Information
        Designation: CPU0_PE1_SLOT3
        Type: x16 <OUT OF SPEC>
        Current Usage: In Use
        Length: Long
        Characteristics:
                3.3 V is provided
                Opening is shared
                PME signal is supported
        Bus Address: 0000:34:00.0

可以看到BUS对应的卡槽为SLOT3，SLOT标号一般在主板上，白色字体，在每个PCIE插槽（很长的那个插槽，插显卡的）的上方。

还可以通过 dmidecode -t slot | egrep -i "slot|add" 查看 （输出更简洁），输出类似于：

[root@localhost ~]# dmidecode -t slot | egrep -i "slot|add"
System Slot Information
        Bus Address: 0000:33:00.0
System Slot Information
        Designation: CPU0_PE1_SLOT3
        Bus Address: 0000:34:00.0
System Slot Information
        Designation: CPU0_PE1_SLOT2
        Bus Address: 0000:35:00.0
System Slot Information
        Designation: CPU0_PE1_SLOT1
        Bus Address: 0000:36:00.0
System Slot Information
        Designation: CPU0_PE1_SLOT0
        Bus Address: 0000:37:00.0
System Slot Information
        Bus Address: 0000:4b:00.0
System Slot Information
        Bus Address: 0000:65:00.0

        Designation: CPU1_PE0_SLOT7
        Bus Address: 0000:9b:00.0
System Slot Information
        Designation: CPU1_PE0_SLOT6
        Bus Address: 0000:9c:00.0
System Slot Information
        Designation: CPU1_PE0_SLOT5
        Bus Address: 0000:9d:00.0
System Slot Information
        Designation: CPU1_PE0_SLOT4
        Bus Address: 0000:9e:00.0

直接查看显卡SN序列号：

[root@localhost ~]# nvidia-smi -q | grep 'Serial Number'
    Serial Number                         : 13217220*****
    Serial Number                         : 13217220*****
    Serial Number                         : 13217220*****
    Serial Number                         : 13217220*****
    Serial Number                         : 13217220*****
    Serial Number                         : 13217220*****
    Serial Number                         : 13217220*****
    Serial Number                         : 13217220*****

6、查看硬盘信息

1、用“df -h”命令；2、用“lsblk”命令；3、用“sudo lshw -class disk”命令；4、用“fdisk -l”命令；5、用“cat /proc/partitions”命令；6、用“lsscsi”命令

7、查看内存插槽信息及使用情况

[root@localhost ~]# dmidecode -t memory | grep Size
        Size: 8192 MB
        Size: 8192 MB
        Size: 16384 MB
        Size: 16384 MB
