Windows下面查看硬件配置信息，通常我们会去下载相关软件，软件会给我们提供非常直观的方式。虽然在Linux下面也有这类的软件，但大家通常不这么做，习惯于使用内置的命令查看。原因大家都知道，因为作为服务器角色的Linux系统通常不会安装GUI桌面的。这些命令其实也很简单，我在这里归纳总结下吧。
一、查看主板 查看主板型号 dmidecode -t baseboard SMBIOS 2.4 present. Handle 0x0002, DMI type 2, 8 bytes Base Board Information Manufacturer: Gigabyte Technology Co., Ltd. Product Name: G41MT-D3 #这是我的主板型号啦 Version: Serial Number: |
查看BIOS信息
dmidecode -t bios ...... BIOS Information Vendor: American Megatrends Inc. Version: 4.6.5 Release Date: 04 /25/2012 ....... BIOS Revision: 4.6 ...... |
二、查看CPU
通过lscpu命令查看 lscpu Architecture: x86_64 CPU op -mode(s): 32-bit, 64-bit CPU(s): 1 Thread(s) per core: 1 Core(s) per socket: 1 CPU socket(s): 1 NUMA node(s): 1 Vendor ID: GenuineIntel CPU family: 15 Model: 4 Stepping: 9 CPU MHz: 2800.135 L1d cache: 16K L2 cache: 256K |
查看/proc/cpuinfo文件，获取CPU详细参数。
cat /proc/cpuinfo processor : 0 vendor_id : GenuineIntel cpu family : 15 model : 4 model name : Intel(R) Celeron(R) CPU 2.80GHz #CPU型号 stepping : 9 cpu MHz : 2800.135 cache size : 256 KB fpu : yes fpu_exception : yes cpuid level : 5 wp : yes flags : fpu vme de pse tsc msr pae mce... bogomips : 5600.27 clflush size : 64 cache_alignment : 128 address sizes : 36 bits physical, 48 bits virtual power management: |
三、查看内存
内存使用情况 free -m total used free shared buffers cached Mem: 1977 1254 722 0 150 564 -/+ buffers /cache : 539 1438 Swap: 3858 0 3858 |
内存硬件信息
dmidecode -t memory SMBIOS 2.7 present. Handle 0x0008, DMI type 16, 23 bytes Physical Memory Array Location: System Board Or Motherboard .... Maximum Capacity: 32 GB .... Handle 0x000A, DMI type 17, 34 bytes .... Memory Device Array Handle: 0x0008 Error Information Handle: Not Provided Total Width: 64 bits Data Width: 64 bits Size: 4096 MB ..... |
四、查看网卡
网卡型号 lspci| grep -i 'eth' 02:00.0 Ethernet controller: Realtek Semiconductor Co., Ltd. RTL8111 /8168B PCI Express Gigabit Ethernet controller (rev 06) |
参数和指标
ethtool eth0 Settings for eth0: Supported ports: [ TP MII ] Supported link modes: 10baseT /Half 10baseT /Full baseT /Half 100baseT /Full baseT /Half 1000baseT /Full Supported pause frame use: No Supports auto-negotiation: Yes Advertised link modes: 10baseT /Half 10baseT /Full baseT /Half 100baseT /Full baseT /Half 1000baseT /Full Advertised pause frame use: Symmetric Receive-only Advertised auto-negotiation: Yes Link partner advertised link modes: 10baseT /Half 10baseT /Full baseT /Half 100baseT /Full ..... Speed: 100Mb /s Duplex: Full ..... Link detected: yes |
五、查看硬盘
挂载和使用情况 df -h Filesystem Size Used Avail Use% Mounted on /dev/sda1 323M 148M 159M 49% / tmpfs 989M 0 989M 0% /lib/init/rw udev 984M 172K 984M 1% /dev tmpfs 989M 0 989M 0% /dev/shm /dev/sda9 444G 62G 360G 15% /home /dev/sda8 368M 11M 339M 3% /tmp /dev/sda5 8.3G 1.5G 6.5G 19% /usr /dev/sda6 2.8G 551M 2.1G 21% /var |
分区详细信息
fdisk -l Disk /dev/sda : 500.1 GB, 500107862016 bytes 255 heads, 63 sectors /track , 60801 cylinders Units = cylinders of 16065 * 512 = 8225280 bytes Sector size (logical /physical ): 512 bytes / 512 bytes I /O size (minimum /optimal ): 512 bytes / 512 bytes Disk identifier: 0x0001ef9d Device Boot Start End Blocks Id System /dev/sda1 * 1 43 340992 83 Linux Partition 1 does not end on cylinder boundary. /dev/sda2 43 60802 488042497 5 Extended /dev/sda5 43 1137 8787968 83 Linux /dev/sda6 1137 1502 2928640 83 Linux /dev/sda7 1502 1994 3951616 82 Linux swap / Solaris /dev/sda8 1994 2043 389120 83 Linux /dev/sda9 2043 60802 471981056 83 Linux |
