Linux系统查看服务器型号、CPU、RAM、ROM以及网卡信息

首先是CPU方面的：
查看CPU型号

# cat /proc/cpuinfo | grep name | cut -f2 -d: | uniq -c      8  Intel(R) Xeon(R) CPU E5-2609 v2 @ 2.50GHz

查看物理CPU个数

# cat /proc/cpuinfo| grep "physical id"| sort| uniq| wc -l2

查看CPU核心数

# cat /proc/cpuinfo| grep "cpu cores"| uniqcpu cores   : 4

查看逻辑CPU个数

# cat /proc/cpuinfo| grep "processor"| wc -l8

查看服务器型号
方法一

# grep 'DMI' /var/log/dmesgDMI: Dell Inc. PowerEdge R720/******, BIOS 2.4.3 07/09/2014

方法二

Product Name: PowerEdge R720    Version: Not Specified    Serial Number: *******

查看是32位还是64位系统

# uname -aLinux **** 2.6.32-642.el6.x86_64 #1 SMP Tue May 10 17:27:01 UTC 2016 x86_64 x86_64 x86_64 GNU/Linux

查看RAM
方法一

方法二 (还查看到了swap分区的大小)

# free -m             total       used       free     shared    buffers     cachedMem:         32057       2573      29484         19        157       1442-/+ buffers/cache:        973      31084Swap:        16095          0      16095
