dmidecode 用于获取主机的硬件信息，通常是在不打开计算机机箱的情况下使用该命令来查找硬件详细信息，常见用法如下：
[root@localhost ~]$ yum install -y dmidecode
[root@localhost ~]$ dmidecode # 打印所有硬件信息 [root@localhost ~]$ dmidecode -q # 打印所有硬件信息，比较简洁 [root@localhost ~]$ dmidecode | grep 'Product Name' # 以过滤的方式来查看指定的硬件信息 [root@localhost ~]$ dmidecode --type bios # 查看BIOS相关的硬件信息 [root@localhost ~]$ dmidecode --type system # 查看系统相关的硬件信息 [root@localhost ~]$ dmidecode --type baseboard # 查看主板相关的硬件信息 [root@localhost ~]$ dmidecode --type chassis # 查看机箱相关的硬件信息 [root@localhost ~]$ dmidecode --type processor # 查看处理器相关的硬件信息 [root@localhost ~]$ dmidecode --type memory # 查看内存相关的硬件信息
[root@localhost ~]$ dmidecode -q //BIOS相关的硬件信息 BIOS Information Vendor: Bochs Version: Bochs Release Date: 01/01/2011 Address: 0xE8000 Runtime Size: 96 kB ROM Size: 64 kB Characteristics: BIOS characteristics not supported Targeted content distribution is supported BIOS Revision: 1.0 //系统相关的硬件信息 System Information Manufacturer: Bochs # 厂商 Product Name: Bochs # 服务器型号 Version: Not Specified # 版本号 Serial Number: 641ab5b5-f6c0-431f-864c-4e750d27de04 # 主板序列号 UUID: 641AB5B5-F6C0-431F-864C-4E750D27DE04 # UUID Wake-up Type: Power Switch SKU Number: Not Specified Family: Not Specified //机箱相关的硬件信息 Chassis Information Manufacturer: Bochs Type: Other Lock: Not Present Version: Not Specified Serial Number: Not Specified Asset Tag: Not Specified Boot-up State: Safe Power Supply State: Safe Thermal State: Safe Security Status: Unknown OEM Information: 0x00000000 Height: Unspecified Number Of Power Cords: Unspecified //处理器相关的硬件信息 Processor Information Socket Designation: CPU 1 Type: Central Processor Family: Other Manufacturer: Bochs ID: F1 06 04 00 FF FB 8B 1F Version: Not Specified Voltage: Unknown External Clock: Unknown Max Speed: 2000 MHz Current Speed: 2000 MHz Status: Populated, Enabled Upgrade: Other //物理内存阵列 Physical Memory Array Location: Other Use: System Memory Error Correction Type: Multi-bit ECC Maximum Capacity: 2 GB Number Of Devices: 1 //内存设备 Memory Device Total Width: 64 bits Data Width: 64 bits Size: 2048 MB Form Factor: DIMM Set: None Locator: DIMM 0 Bank Locator: Not Specified Type: RAM Type Detail: None //内存阵列映射地址 Memory Array Mapped Address Starting Address: 0x00000000000 Ending Address: 0x0007FFFFFFF Range Size: 2 GB Partition Width: 1 //内存设备映射地址 Memory Device Mapped Address Starting Address: 0x00000000000 Ending Address: 0x0007FFFFFFF Range Size: 2 GB Partition Row Position: 1 //系统引导 System Boot Information Status: No errors detected
