① linux如何查看伺服器序列號
1、單獨查看伺服器的序列號
[root@localhost ~]# dmidecode -t system | grep 'Serial Number'
Serial Number: 2102310YPY10J30*****
2、單獨查看伺服器型號
[root@localhost ~]# dmidecode | grep "Proct"
Proct Name: PowerEdge R730
Proct Name: 0WCJNT
3、統一查看伺服器SN序列號和型號
[root@localhost ~]# dmidecode | grep "System Information" -A9 | egrep "Manufacturer|Proct|Serial"
Manufacturer: Huawei 廠商
Proct Name: RH2288 V3 型號
Serial Number: 2102310YPY10J3****** 序列號
4、查看內存條信息及使用情況（內存的插槽數,已經使用多少插槽.每條內存多大，下圖為16個內存插糟，用了12個插槽，每根內存條16G）《Linux就該這么學》一起學習linux
