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 -l 2

查看CPU核心数

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

查看逻辑CPU个数

# cat /proc/cpuinfo| grep "processor"| wc -l 8

查看服务器型号方法一

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

方法二

# yum -y install dmidecode Loaded plugins: fastestmirror, refresh-packagekit Setting up Install Process Loading mirror speeds from cached hostfile * base: mirrors.sohu.com * epel: mirrors.sohu.com * extras: mirrors.aliyun.com * linuxtech-release: linuxsoft.cern.ch * remi-safe: mirror.innosol.asia * updates: mirrors.sohu.com Package 1:dmidecode-2.12-7.el6.x86_64 already installed and latest version Nothing to do # dmidecode |grep -A4 'System Information' System Information Manufacturer: Dell Inc. Product Name: PowerEdge R720 Version: Not Specified Serial Number: *******

查看是32位还是64位系统

# uname -a Linux **** 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

# cat /proc/meminfo MemTotal: 32826948 kB MemFree: 30190792 kB Buffers: 161544 kB Cached: 1476004 kB SwapCached: 0 kB Active: 1377540 kB Inactive: 814108 kB Active(anon): 554320 kB Inactive(anon): 20080 kB Active(file): 823220 kB Inactive(file): 794028 kB Unevictable: 0 kB Mlocked: 0 kB SwapTotal: 16482300 kB SwapFree: 16482300 kB Dirty: 5112 kB Writeback: 0 kB AnonPages: 553972 kB Mapped: 129264 kB Shmem: 20308 kB Slab: 185168 kB SReclaimable: 103320 kB SUnreclaim: 81848 kB KernelStack: 7968 kB PageTables: 19384 kB NFS_Unstable: 0 kB Bounce: 0 kB WritebackTmp: 0 kB CommitLimit: 32895772 kB Committed_AS: 2453404 kB VmallocTotal: 34359738367 kB VmallocUsed: 339064 kB VmallocChunk: 34342499988 kB HardwareCorrupted: 0 kB AnonHugePages: 280576 kB HugePages_Total: 0 HugePages_Free: 0 HugePages_Rsvd: 0 HugePages_Surp: 0 Hugepagesize: 2048 kB DirectMap4k: 5056 kB DirectMap2M: 2045952 kB DirectMap1G: 31457280 kB

方法二 (还查看到了swap分区的大小)

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

查看ROM 方法一

# cat /proc/partitions major minor #blocks name 7 0 2168646 loop0 7 1 3824640 loop1 8 0 975699968 sda 8 1 512000 sda1 8 2 975186944 sda2 253 0 52428800 dm-0 253 1 16482304 dm-1 253 2 906272768 dm-2

方法二
