linux系統查看主板型號,cpu,記憶體,記憶體條數量,網卡資訊

說明：

因為種種原來，我們可能需要查看linux伺服器主板型號，cpu型號，記憶體大小，記憶體條數量等。因為伺服器使用raid卡，平常查看硬碟資訊的命令還不能用，待後面補充！

查看主板型號

代碼如下

複製代碼

# dmidecode |grep -A 8 "System Information"  System Information         Manufacturer: Dell                          Product Name: CS24-TY                       Version: A00                           Serial Number: 24Z1NL1                       UUID: 2656CFCF-887A-0010-BBD8-00269E9C46DC         Wake-up Type: Power Switch         SKU Number: To Be Filled By O.E.M.         Family: Server上網查DELL CS24-TY，找到說主板型號是DELL PowerEdge C1100

查看記憶體

[root@localhost ~]# df -h Filesystem            Size  Used Avail Use% Mounted on /dev/sda3             119G   17G   96G  15% / tmpfs                  16G     0   16G   0% /dev/shm /dev/sda1              97M   32M   61M  35% /boot

查看raid卡，raid卡為DELL PERC 6/i

# dmidecode |grep -A16 "Memory Device$"

查看cpu型號，主頻

代碼如下

複製代碼

# cat /proc/cpuinfo | grep name | cut -f2 -d: | uniq -c       8  Intel(R) Xeon(R) CPU            E5410   @ 2.33GHz (看到有8個邏輯CPU, 也知道了CPU型號) # cat /proc/cpuinfo | grep physical | uniq -c       4 physical id      : 0       4 physical id      : 1 (說明實際上是兩顆4核的CPU) # 其實是可能有超執行緒HT技術，不一定是有4核，也可能是2核4線程。 # getconf LONG_BIT    32 (說明當前CPU運行在32bit模式下, 但不代表CPU不支援64bit) # cat /proc/cpuinfo | grep flags | grep ' lm ' | wc -l    8 (結果大於0, 說明支援64bit計算. lm指long mode, 支援lm則是64bit) 完整查看cpu詳細資料。 # dmidecode | grep -A81 'Processor Information'
