dmidecode 用於獲取主機的硬件信息，通常是在不打開計算機機箱的情況下使用該命令來查找硬件詳細信息，常見用法如下：
[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，比較簡潔 [root@localhost ~]$ dmidecode | grep 'Product Name' # 以過濾的方式來查看指定的硬件信息 [root@localhost ~]$ dmidecode --type bios # 查看BIOS相關的硬件信息 [root@localhost ~]$ dmidecode --type system # 查看系統相關的硬件信息 [root@localhost ~]$ dmidecode --type baseboard # 查看主板相關的硬件信息 [root@localhost ~]$ dmidecode --type chassis # 查看機箱相關的硬件信息 [root@localhost ~]$ dmidecode --type processor # 查看處理器相關的硬件信息 [root@localhost ~]$ dmidecode --type memory # 查看內存相關的硬件信息
[root@localhost ~]$ dmidecode -q //BIOS相關的硬件信息 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 //系統相關的硬件信息 System Information Manufacturer: Bochs # 廠商 Product Name: Bochs # 服務器型號 Version: Not Specified # 版本號 Serial Number: 641ab5b5-f6c0-431f-864c-4e750d27de04 # 主板序列號 UUID: 641AB5B5-F6C0-431F-864C-4E750D27DE04 # UUID Wake-up Type: Power Switch SKU Number: Not Specified Family: Not Specified //機箱相關的硬件信息 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 //處理器相關的硬件信息 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 //物理內存陣列 Physical Memory Array Location: Other Use: System Memory Error Correction Type: Multi-bit ECC Maximum Capacity: 2 GB Number Of Devices: 1 //內存設備 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 //內存陣列映射地址 Memory Array Mapped Address Starting Address: 0x00000000000 Ending Address: 0x0007FFFFFFF Range Size: 2 GB Partition Width: 1 //內存設備映射地址 Memory Device Mapped Address Starting Address: 0x00000000000 Ending Address: 0x0007FFFFFFF Range Size: 2 GB Partition Row Position: 1 //系統引導 System Boot Information Status: No errors detected
