How to check hardware configuration information in Linux

This article mainly shares with you how to check the hardware configuration information in Linux. It has a good reference value and I hope it will be helpful to everyone. Let’s follow the editor to have a look.

1.View all hardware information of the machine:

## dmidecode |more

dmesg |more

The information from these 2 commands are all There are a lot of ,, so it is recommended to use "|more" for easy viewing

##2.View CPUInformation

##Method 1: Under Linux
CPU related parameters are saved in /proc/cpuinfo In the file cat /proc/cpuinfo |more
Method 2
: Use the command
dmesg | grep CPU to view the startup of the related CPU Information View the number of bits of
CPU:

getconf LONG_BIT##3.

View

MemInformation cat/proc/meminfo |more

(Note the last line of the output information

:MachineMem: 41932272 kB) free -m

top

##4.

View disk information

Method 1

: fdisk -l You can see The partitions and sizes of disk
(including Udisk) on the system are related information. Method 2:
View directly
##cat /proc/partitions

5.View network card information

Method 1:
ethtool eth0 Use this command to view the technical indicators related to the network card
(Not all network cards may support this command)
ethtool -i eth1 plus -i Parameters to view the network card driver
You can try other parameters to view the relevant technical parameters of the network card
Method 2:
You can also see the network card name through dmesg | grep eth0 etc.(Manufacturer) and other information
By viewing /etc/sysconfig /network-scripts/ifcfg-eth0 You can see the current network card configuration including IP, gateway address and other information.
Of course, you can also view it through the ifconfig command.

lspci

7.How to mountISOFile
mount -o loop *.isomount_point
8.How to view Disc related information
Method 1:
InsertCD After disc, in my RHEL5 system, the CD file is /dev/cdrom ,
So just mount/dev/cdrom mount_point .
[root@miix tmp]# mount /dev/cdrom mount_point
mount: block device /dev/cdrom is write-protected, mountingread-only
In fact, if you look carefully, the device file of the optical drive is hdc
[root@miix tmp]# ls -l /dev/cdrom*
lrwxrwxrwx 1 root root 3 01-08 08:54 / dev/cdrom -> hdc
lrwxrwxrwx 1 root root 3 01-08 08:54 /dev/cdrom-hdc -> hdc
So we can also do this mount /dev/hdcmount_point
If a valid CD is not placed in the optical drive, an error will be reported:
[root@miix tmp]# mount /dev/hdc mount_point
mount: Media not found
9.How to checkUSBDevice related

Method 1:
In fact, you can view it through the fdisk -l command To access the U disk information, my U disk information is as follows:

Disk /dev/sda: 2012 MB, 2012217344 bytes
16 heads, 32 sectors/track, 7676 cylinders
Units = cylinders of 512 * 512 = 262144 bytes

Device Boot Start End Blocks Id System
/dev/sda1 * 16 7676 1961024 b W95 FAT32

The device file of U disk is /dev/sda, 2G size, FAT32 format.

If the user is not logging in to the Linux graphical interface, UThe disk will not be automatically mounted.
You can mount it manually at this time(mount)：
mount /dev /sda1 mount_point
The above command will mount the U disk to the mount_point directory in the current directory. Note that sda1 is not sda.
The uninstall command is umountmount_point

Linuxdoes not have built-in support by defaultNTFS format disk driver, but has good support for FAT32, generally not needed when mounting -t vfat parameter.
If ntfs is supported, the disk partition in the ntfs format should be Use -t ntfs parameters.
If garbled characters appear, you can consider using the -o iocharset=character set parameter.

You can view the USB device information through the lsusb command Oh:

[root@miix tmp]# lsusb
Bus 001 Device 001: ID 0000:0000
Bus 002 Device 001: ID 0000:0000
Bus 003 Device 001: ID 0000:0000
Bus 004 Device 002: ID 0951:1613 Kingston Technology
Bus 004 Device 001: ID 0000:0000
