搞运维的朋友都会遇到服务器故障的时候，小编服务器昨天出现问题了。一开始以为只是没有找到键盘呢，其实插着键盘呢，折腾了半天bios也没有什么发现，最后还是一位有经验的朋友说，B1内存脏了。呵呵。果真是这样，拆机擦擦装上去搞定了。。回到公司赶紧查查服务器硬件的情况，怎么查呢，有没有linux版本的360或者鲁大师之类的软件呢，看来是我多想了。
说正经的，看如何查看linux主机的硬件情况吧。
[root@localhost ~]# cat /proc/cpuinfo | grep "physical id" | uniq | wc -l 4 [root@localhost ~]#
[root@localhost ~]# dmidecode |grep -A16 "Memory Device$" Memory Device Array Handle: 0x0032 Error Information Handle: Not Provided Total Width: 72 bits Data Width: 64 bits Size: No Module Installed Form Factor: DIMM Set: None Locator: DIMM_A1 Bank Locator: BANK0 Type: DDR3 Type Detail: Other Speed: Unknown Manufacturer: Manufacturer0 Serial Number: SerNum1 Asset Tag: AssetTagNum1 Part Number: PartNum1 -- Memory Device Array Handle: 0x0032 Error Information Handle: Not Provided Total Width: 72 bits Data Width: 64 bits Size: 8192 MB Form Factor: DIMM Set: None Locator: DIMM_B1 Bank Locator: BANK1 Type: DDR3 Type Detail: Other Speed: 1333 MHz Manufacturer: Manufacturer1 Serial Number: SerNum2 Asset Tag: AssetTagNum2 Part Number: PartNum2
............更多的就不显示了，就拿上边两个特色的例子来。
留意看Size位置：No Module Installed是空曹位
[root@localhost ~]# cat /proc/meminfo | grep MemTotal MemTotal: 8050264 kB [root@localhost ~]#
[root@localhost ~]# cat /proc/cpuinfo | grep "cpu cores" | uniq cpu cores : 4 [root@localhost ~]#
[root@localhost ~]# cat /proc/cpuinfo | grep 'model name' |uniq model name : Intel(R) Xeon(R) CPU E5620 @ 2.40GHz You have mail in /var/spool/mail/root [root@localhost ~]#
硬盘应该都知道 fdisk -l
