一、查看服务器硬件信息

（1）查看服务器型号、序列号

[root@Master ~]# dmidecode|grep "System Information" -A9|egrep  "Manufacturer|Product|Serial" 

 （2）查看主板型号

[root@Master ~]# dmidecode |grep -A16 "System Information$" 

3）查看BIOS信息

[root@Master ~]# dmidecode -t bios

# dmidecode 2。12

SMBIOS 2。8 present。

Handle 0x0008, DMI type 0, 24 bytes
