1. lscpu用于查询CPU信息
[root@devops ~]# lscpu Architecture: x86_64 CPU op-mode(s): 32-bit, 64-bit Byte Order: Little Endian CPU(s): 1 On-line CPU(s) list: 0 Thread(s) per core: 1 Core(s) per socket: 1 CPU socket(s): 1 NUMA node(s): 1 Vendor ID: GenuineIntel CPU family: 6 Model: 45 Stepping: 7 CPU MHz: 2194.842 BogoMIPS: 4389.68 Hypervisor vendor: Xen Virtualization type: full L1d cache: 32K L1i cache: 32K L2 cache: 256K L3 cache: 15360K NUMA node0 CPU(s): 0
2. lshw显示硬件信息表
这个命令应用普遍，它可通过个人需求而列出多种不同的硬件参数：CPU、内存、硬盘、USB控制器、lshw卡片等等，本质上就是从/proc目录不同文件中中提取对应的硬件信息。
按照下面的步骤去安装lshw工具，然后就可以使用了。
wget http://ezix.org/software/files/lshw-B.02.14.tar.gz tar -zxvf lshw-B.02.14.tar.gz cd lshw-B.02.14 make && make install 示例： [root@devops lshw-B.02.14]# lshw -short H/W path Device Class Description ===================================================== system HVM domU /0 bus Motherboard /0/0 memory 96KiB BIOS /0/1 processor Intel(R) Xeon(R) CPU E5-2430 0 @ 2.20GHz /0/2 memory System Memory /0/2/0 memory 512MiB DIMM RAM /0/2/1 memory 512MiB DIMM RAM /0/3 memory 96KiB BIOS /0/4 processor CPU /0/5 memory System Memory /0/6 memory /0/7 memory /0/100 bridge 440FX - 82441FX PMC [Natoma] /0/100/1 bridge 82371SB PIIX3 ISA [Natoma/Triton II] /0/100/1.1 scsi1 storage 82371SB PIIX3 IDE [Natoma/Triton II] /0/100/1.1/0.0.0 /dev/cdrom1 disk SCSI CD-ROM /0/100/1.2 bus 82371SB PIIX3 USB [Natoma/Triton II] /0/100/1.2/1 usb1 bus UHCI Host Controller /0/100/1.2/1/2 input QEMU USB Tablet /0/100/1.3 bridge 82371AB/EB/MB PIIX4 ACPI /0/100/2 display GD 5446 /0/100/3 generic Xen Platform Device /1 eth0 network Ethernet interface /2 eth2 network Ethernet interface [root@devops lshw-B.02.14]#
3. hwinfo-硬件信息
hwinfo类似于lshw，也能查询硬件信息，且应用广泛。它也能输出多个硬件部分的详细或者简要信息，但是不同的是有时hwinfo比lshw的信息更详细。
默认情况下，Linux系统没有安装hwinfo工具，所以你需要按照以下步骤自己安装：
CentOS 6
#rpm -Uvh http://mirror.symnds.com/distributions/gf/el/6/gf/x86_64/gf-release-6-6.gf.el6.noarch.rpm #yum list hwinfo #yum install hwinfo
CentOS 5
#rpm -Uvh http://mirror.symnds.com/distributions/gf/el/5/gf/x86_64/gf-release-5-6.gf.el5.noarch.rpm #yum list hwinfo #yum install hwinfo
[root@devops tmp]# rpm -Uvh http://mirror.symnds.com/distributions/gf/el/6/gf/x86_64/gf-release-6-6.gf.el6.noarch.rpm Retrieving http://mirror.symnds.com/distributions/gf/el/6/gf/x86_64/gf-release-6-6.gf.el6.noarch.rpm warning: /var/tmp/rpm-tmp.m2mMAO: Header V4 RSA/SHA1 Signature, key ID 13a4d2a9: NOKEY Preparing... ########################################### [100%] 1:gf-release ########################################### [100%] [root@devops tmp]# yum list hwinfo Loaded plugins: fastestmirror Loading mirror speeds from cached hostfile * base: mirrors.aliyun.com * extras: mirrors.aliyun.com * updates: mirrors.aliyun.com gf 00:00 gf/primary_db 00:00 Available Packages hwinfo.x86_64 [root@devops tmp]# yum list hwinfo Loaded plugins: fastestmirror Loading mirror speeds from cached hostfile * base: mirrors.aliyun.com * extras: mirrors.aliyun.com * updates: mirrors.aliyun.com gf 00:00 gf/primary_db 00:00 Available Packages hwinfo.x86_64 20.2-1.gf.el6

示例：
[root@devops tmp]# hwinfo -short oops: don't know what to do with "short" [root@devops tmp]# hwinfo --short cpu: Intel(R) Xeon(R) CPU E5-2430 0 @ 2.20GHz, 2194 MHz keyboard: /dev/input/event3 AT Translated Set 2 keyboard /dev/ttyS0 serial console mouse: /dev/input/mice Adomax QEMU USB Tablet /dev/input/mice Macintosh mouse button emulation /dev/input/mice ImExPS/2 Generic Explorer Mouse graphics card: Cirrus Logic GD 5446 storage: Intel 82371SB PIIX3 IDE [Natoma/Triton II] Xen Virtual Storage 0 Xen Virtual Storage 1 Xen Virtual Storage 2 network: eth0 Xen Virtual Ethernet Card 0 eth2 Xen Virtual Ethernet Card 1 network interface: lo Loopback network interface eth0 Ethernet network interface eth2 Ethernet network interface disk: /dev/xvda Disk /dev/xvdb Disk partition: /dev/xvda1 Partition /dev/xvdb1 Partition cdrom: /dev/sr0 QEMU DVD-ROM usb controller: Qumranet Qemu virtual machine bios: BIOS bridge: Qumranet Qemu virtual machine Qumranet Qemu virtual machine Qumranet Qemu virtual machine hub: Linux 2.6.32-279.el6.x86_64 uhci_hcd UHCI Host Controller memory: Main Memory unknown: FPU DMA controller PIC Timer Keyboard controller XenSource Xen Platform Device [root@devops tmp]#
4. lspci
lsppci命令可列出PCI总线的信息以及连接到PCI总线上的设备信息，比如VGA适配器、SATA控制器、其他模块等等。lspci工具是pciutils包的一部分，所以在安装lspci之前，你需要安装pciutils包。
安装pciutils包使用下面的命令：
#yum install pciutils
[root@devops tmp]# yum install pciutils Loaded plugins: fastestmirror Loading mirror speeds from cached hostfile * base: mirrors.aliyun.com * extras: mirrors.aliyun.com * updates: mirrors.aliyun.com Setting up Install Process Resolving Dependencies --> Running transaction check ---> Package pciutils.x86_64 0:3.1.10-2.el6 will be installed --> Processing Dependency: pciutils-libs = 3.1.10-2.el6 for package: pciutils-3.1.10-2.el6.x86_64 --> Running transaction check ---> Package pciutils-libs.x86_64 0:3.1.4-11.el6 will be updated ---> Package pciutils-libs.x86_64 0:3.1.10-2.el6 will be an update --> Finished Dependency Resolution Dependencies Resolved Installing: pciutils x86_64 3.1.10-2.el6 85 k Updating for dependencies: pciutils-libs x86_64 3.1.10-2.el6 34 k .....
