首先檢視是否安裝了dmidecode工具

[[email protected] ~]# dmidecode

1. Linux 檢視記憶體的插槽數,已經使用多少插槽.每條記憶體多大：
   [[email protected] ~]# dmidecode|grep -A5 "Memory Device"|grep Size|grep -v Range
   Size: 4096 MB
   Size: 4096 MB
   Size: No Module Installed
   Size: No Module Installed

2. Linux 檢視記憶體的頻率：
   [[email protected]

   ~]# dmidecode|grep -A16 "Memory Device"|grep 'Speed'
   Speed: 2400 MT/s
   Speed: 2400 MT/s
   Speed: Unknown
   Speed: Unknown

3. 在linux檢視記憶體型號的命令：
   [[email protected] ~]# dmidecode -t memory

4. 最大支援幾G記憶體
   [[email protected] ~]# dmidecode|grep -P 'Maximum\s+Capacity'

5. 檢視主機板型號：
   [[email protected] ~]# dmidecode |grep -A16 "System Information$"

6. 記憶體槽及記憶體條：
   [[email protected] ~]# dmidecode |grep -A16 "Memory Device$"

7. 總共幾個插槽，已使用幾個插槽
   [[email protected] ~]# dmidecode|grep -P -A5 "Memory\s+Device"|grep Size|grep -v Range

8. 硬碟：
   [[email protected] ~]# fdisk -l
[[email protected] ~]# smartctl -a /dev/sda

9. 網絡卡：
   [[email protected]

   ~]# mii-tool

10. 檢視cpu個數與頻率
    [[email protected] ~]# cat /proc/cpuinfo

11. 檢視系統品牌和型號
    [[email protected] ~]# dmidecode |grep "Product Name"
