1、查詢cpu的相關
a、查詢CPU的統計信息
使用命令:lscpu
得到的結果如下:
Architecture: x86_64 CPU op-mode(s): 32-bit, 64-bit Byte Order: Little Endian CPU(s): 12 On-line CPU(s) list: 0-11 Thread(s) per core: 1 Core(s) per socket: 6 Socket(s): 2 NUMA node(s): 2 Vendor ID: GenuineIntel CPU family: 6 Model: 62 Stepping: 4 CPU MHz: 2099.939 BogoMIPS: 4199.44 Virtualization: VT-x L1d cache: 32K L1i cache: 32K L2 cache: 256K L3 cache: 15360K NUMA node0 CPU(s): 0-5 NUMA node1 CPU(s): 6-11
b、查詢每個CPU信息
使用的命令:cat /proc/cpuinfo
得到如下結果:

2、查詢所有的pci設備信息(pci是一種總線,而通過pci總線連接的設備就是pci設備了,如今,我們常用的設備很多都采用pci總線了,如網卡存儲等)
使用命令:lspci
得到結果:
0:00.0 Host bridge: Intel Corporation Xeon E5 v2/Core i7 DMI2 (rev 04) 00:01.0 PCI bridge: Intel Corporation Xeon E5 v2/Core i7 PCI Express Root Port 1a (rev 04) 00:01.1 PCI bridge: Intel Corporation Xeon E5 v2/Core i7 PCI Express Root Port 1b (rev 04) 00:02.0 PCI bridge: Intel Corporation Xeon E5 v2/Core i7 PCI Express Root Port 2a (rev 04) 00:03.0 PCI bridge: Intel Corporation Xeon E5 v2/Core i7 PCI Express Root Port 3a (rev 04) 00:03.2 PCI bridge: Intel Corporation Xeon E5 v2/Core i7 PCI Express Root Port 3c (rev 04) 00:04.0 System peripheral: Intel Corporation Xeon E5 v2/Core i7 Crystal Beach DMA Channel 0 (rev 04) 00:04.1 System peripheral: Intel Corporation Xeon E5 v2/Core i7 Crystal Beach DMA Channel 1 (rev 04) 00:04.2 System peripheral: Intel Corporation Xeon E5 v2/Core i7 Crystal Beach DMA Channel 2 (rev 04) 00:04.3 System peripheral: Intel Corporation Xeon E5 v2/Core i7 Crystal Beach DMA Channel 3 (rev 04) 00:04.4 System peripheral: Intel Corporation Xeon E5 v2/Core i7 Crystal Beach DMA Channel 4 (rev 04) 00:04.5 System peripheral: Intel Corporation Xeon E5 v2/Core i7 Crystal Beach DMA Channel 5 (rev 04) 00:04.6 System peripheral: Intel Corporation Xeon E5 v2/Core i7 Crystal Beach DMA Channel 6 (rev 04) 00:04.7 System peripheral: Intel Corporation Xeon E5 v2/Core i7 Crystal Beach DMA Channel 7 (rev 04) 00:05.0 System peripheral: Intel Corporation Xeon E5 v2/Core i7 VTd/Memory Map/Misc (rev 04) 00:05.2 System peripheral: Intel Corporation Xeon E5 v2/Core i7 IIO RAS (rev 04) 00:05.4 PIC: Intel Corporation Xeon E5 v2/Core i7 IOAPIC (rev 04) 00:11.0 PCI bridge: Intel Corporation C600/X79 series chipset PCI Express Virtual Root Port (rev 06) 00:16.0 Communication controller: Intel Corporation C600/X79 series chipset MEI Controller #1 (rev 05) 00:16.1 Communication controller: Intel Corporation C600/X79 series chipset MEI Controller #2 (rev 05) 00:1a.0 USB controller: Intel Corporation C600/X79 series chipset USB2 Enhanced Host Controller #2 (rev 06) 00:1d.0 USB controller: Intel Corporation C600/X79 series chipset USB2 Enhanced Host Controller #1 (rev 06) 00:1e.0 PCI bridge: Intel Corporation 82801 PCI Bridge (rev a6) 00:1f.0 ISA bridge: Intel Corporation C600/X79 series chipset LPC Controller (rev 06) 00:1f.2 SATA controller: Intel Corporation C600/X79 series chipset 6-Port SATA AHCI Controller (rev 06) 00:1f.3 SMBus: Intel Corporation C600/X79 series chipset SMBus Host Controller (rev 06) 00:1f.6 Signal processing controller: Intel Corporation C600/X79 series chipset Thermal Management Controller (rev 06) 02:00.0 Ethernet controller: Intel Corporation I350 Gigabit Network Connection (rev 01) 02:00.1 Ethernet controller: Intel Corporation I350 Gigabit Network Connection (rev 01) 06:00.0 Network controller: Mellanox Technologies MT27500 Family [ConnectX-3] 08:04.0 VGA compatible controller: Matrox Electronics Systems Ltd. MGA G200eW WPCM450 (rev 0a)
如果要利用lscpi查詢網卡型號可以使用命令:lspci |grep Ethernet
得到結果:
02:00.0 Ethernet controller: Intel Corporation I350 Gigabit Network Connection (rev 01) 02:00.1 Ethernet controller: Intel Corporation I350 Gigabit Network Connection (rev 01)
3、查詢內存相關信息
a、查看內存大小
使用命令:free
得到內存的一個整體信息如下:
total used free shared buffers cached Mem: 16364948 1623020 14741928 0 549616 291172 -/+ buffers/cache: 782232 15582716 Swap: 16383992 81560 16302432
b、查看詳細信息
使用命令:cat /proc/meminfo
結果:
MemTotal: 16364948 kB MemFree: 14742988 kB Buffers: 549660 kB Cached: 291340 kB SwapCached: 14724 kB Active: 241052 kB Inactive: 646568 kB Active(anon): 32216 kB Inactive(anon): 14800 kB Active(file): 208836 kB Inactive(file): 631768 kB Unevictable: 0 kB Mlocked: 0 kB SwapTotal: 16383992 kB SwapFree: 16302432 kB Dirty: 0 kB Writeback: 0 kB AnonPages: 38996 kB Mapped: 13080 kB Shmem: 388 kB Slab: 340196 kB SReclaimable: 210436 kB SUnreclaim: 129760 kB KernelStack: 4744 kB PageTables: 12496 kB NFS_Unstable: 0 kB Bounce: 0 kB WritebackTmp: 0 kB CommitLimit: 24566464 kB Committed_AS: 553868 kB VmallocTotal: 34359738367 kB VmallocUsed: 429696 kB VmallocChunk: 34349265164 kB HardwareCorrupted: 0 kB AnonHugePages: 8192 kB HugePages_Total: 0 HugePages_Free: 0 HugePages_Rsvd: 0 HugePages_Surp: 0 Hugepagesize: 2048 kB DirectMap4k: 4868 kB DirectMap2M: 2058240 kB DirectMap1G: 14680064 kB
4、查看系統內核相關信息
使用命令:uname -a
結果:
Linux cn13 2.6.32-431.el6.x86_64 #1 SMP Sun Nov 10 22:19:54 EST 2013 x86_64 x86_64 x86_64 GNU/Linux
查看系統版本
使用命令:cat /etc/issue
結果:
Red Hat Enterprise Linux Server release 6.5 (Santiago)
5、利用dmindecode查看硬件信息
查看服務器型號
dmidecode | grep 'product name'
查看主板序列號
dmidecode | grep 'Serial Number'
查看系統序列號
dmidecode -s systems-serial-number
查看內存信息
dmidecode -t memory
查看oem信息
dmidecode -t 11
**6、利用ibstat查看infiniband網卡的信息:
結果:
CA 'mlx4_0' CA type: MT4099 Number of ports: 1 Firmware version: 2.30.8000 Hardware version: 0 Node GUID: 0x002590fffff7761c System image GUID: 0x002590fffff7761f Port 1: State: Active Physical state: LinkUp Rate: 40 Base lid: 85 LMC: 0 SM lid: 229 Capability mask: 0x02514868 Port GUID: 0x002590fffff7761d Link layer: InfiniBand
