在Linux下，我们经常需要查看系统的硬件信息， 这里我罗列了查看系统硬件信息的实用命令，并做了分类，实例解说。 执行环境：ubuntu 16.04 1. cpulscpu命令，查看的是cpu的统计信息. root@ubuntu:/home/peng/#lscpu Architecture:x86_64#cpu架构 CPUop-mode(s):32-bit,64-bit ByteOrder:LittleEndian#小尾序 CPU(s):1#总共有1核 On-lineCPU(s)list:0 Thread(s)percore:1#每个cpu核，只能支持一个线程，即不支持超线程 Core(s)persocket:1 Socket(s):1 NUMAnode(s):1 VendorID:GenuineIntel#cpu产商intel CPUfamily:6 Model:158 Modelname:Intel(R)Core(TM)[email protected] Stepping:9 CPUMHz:3408.070 BogoMIPS:6816.14 Hypervisorvendor:VMware Virtualizationtype:full#支持cpu虚拟化技术 L1dcache:32K L1icache:32K L2cache:256K L3cache:6144K NUMAnode0CPU(s):0查看/proc/cpuinfo,可以知道每个cpu信息，如每个CPU的型号，主频等。 root@ubuntu:/home/peng#cat/proc/cpuinfo processor:0 vendor_id:GenuineIntel cpufamily:6 model:158 modelname:Intel(R)Core(TM)[email protected] stepping:9 microcode:0x48 cpuMHz:3408.070 cachesize:6144KB physicalid:0 siblings:1 coreid:0 cpucores:1 apicid:0 initialapicid:0 fpu:yes fpu_exception:yes cpuidlevel:22 wp:yes ..... 2. 内存概要查看内存情况 root@ubuntu:/home/peng#free-m totalusedfreesharedbuff/cacheavailable Mem:1970702315139521025 Swap:97420954这里的单位是MB，总共的内存是1970MB。 查看内存详细使用 root@ubuntu:/home/peng#cat/proc/meminfo MemTotal:2017516kB MemFree:242020kB MemAvailable:1003240kB Buffers:104192kB Cached:699824kB SwapCached:1832kB Active:696320kB Inactive:639924kB Active(anon):236412kB Inactive(anon):301996kB Active(file):459908kB Inactive(file):337928kB Unevictable:48kB Mlocked:48kB .....查看内存硬件信息 root@ubuntu:/home/peng#dmidecode-tmemory #dmidecode3.0 GettingSMBIOSdatafromsysfs.

02:01.0Ethernetcontroller:IntelCorporation82545EMGigabitEthernetController(Copper)(rev01)查看系统的所有网络接口 root@ubuntu:/home/peng#ifconfig-a ens33Linkencap:EthernetHWaddr00:0c:29:bb:bd:40

pci查看pci信息，即主板所有硬件槽信息。 root@ubuntu:/home/peng#lspci 00:00.0Hostbridge:IntelCorporation82845845(Brookdale)ChipsetHostBridge(rev04)

02:04.1CardBusbridge:O2Micro,Inc.OZ6933CardbusController(rev01)由上述的 输出可以看到，我的电脑上共有3个PCI总线(0号，1号，2号）。在单个系统上，插入多个总线是通过桥（bridge)来完成的，桥是一种用来连接总线 的特殊PCI外设。所以，PCI系统的整体布局组织为树型，我们可以通过上面的lspci输出，来画出我的电脑上的PCI系统的树型结构： 00:00.0(主桥）--00:01.0(PCI桥）-----01:00:0(nVidia显卡） | |---00:1d(USB控制器)--00:1d:0(USB1号控制器） || ||--00:1d:1(USB2号控制器）| |-00:1e:0(PCI桥)--02:00.0(IEEE1394) || ||-02:01.0(8139网卡） || ||-02:04(CardBus桥)-02:04.0(桥1） || ||--02:04.1(桥2) | |-00:1f(多功能板卡)-00:1f:0(ISA桥） | |--00:1f:1(IDE接口) | |--00:1f:3(SMBus) | |--00:1f:5(多媒体声音控制器) | |--00:1f:6(调制解调器)由上图可以得出，我的电脑上共有8个PCI设备，其中0号总线上(主桥)上连有4个，1号总线上连有1个，2号总线上连有3个。00:1f是一个连有5个功能的多功能板卡。 如果要更详细的信息: lspci-v或者lspci-vv如果要看设备树:lscpi -t root@ubuntu:/home/peng#lspci-t 6.

lshw查看所有硬件摘要信息下面命令可以查看所有硬件摘要信息，并输出成一个html文件，把此html文件导出到电脑上，直接打开，可以清楚的看到硬件信息： lshw-html>/hardware.html 8. lsscsi查看SCSI控制器设备的信息可以看到SCSI信息和所有虚拟磁盘以及光驱的信息，如果没有硬件SCSI控制器，那就不会返回信息： root@ubuntu:/home/peng#lsscsi [2:0:0:0]diskVMware,VMwareVirtualS1.0/dev/sda [4:0:0:0]cd/dvdNECVMWarVMwareSATACD011.00/dev/sr0插入一个U盘后再查看： root@ubuntu:/home/peng#lsscsi
