System version: CentOS6.5 x86_64

Introduction

In Linux, without windows, you can easily install a master Lu to view the hardware configuration and run the score comparison, so you can only use commands to view it. The following describes how to view the corresponding hardware information.

1. View CPU information

1. The main configuration file is/proc/cpuinfo

Processor: 0
# Number of the logic processing core in the system. For a single-core processor, the course considers it as its CPU number. For a multi-core processor, it can be a physical core, or a virtual logical core using Hyper-Threading Technology.

# Number of logical physical cores of a single CPU
Core id: 0
# Number of the current physical core in the CPU, which is not necessarily consecutive
Cpu cores: 4
# Number of physical CPU cores of the logical core
Apicid: 0
# Used to identify the numbers of different logical cores. The numbers of each logical core in the system must be different, and the numbers are not necessarily consecutive.
Initial apicid: 0
Fpu: yes
# Floating Point Unit)

2. Common commands:

CPU model: cat/proc/cpuinfo | grep "model name" | uniq | awk '{print $4 "" $5 $6 }'
Number of CPU cores: cat/proc/cpuinfo | grep "model name" | wc-l

II. View memory information

1. The main configuration file is/proc/cpuinfo

# The Sum of LowFree and HighFree, with unused memory kept by the system
Buffers': 17484 kB
# Used to buffer the file size

# The size of the memory used by the cache memory (equal to diskcache minus SwapCache ).
SwapCached: 0 kB
# Size of swap space used by cache memory

2. Common commands

Simple memory information: free-m
View remaining memory: free-m | sed-n'/Mem/p' | awk '{print $3 }'
3. View the motherboard information

1. View the motherboard information

You can use the dmidecode command to view the tool. If the tool is not installed, it may fail to be executed. You can use the following command to install the tool:

Yum install dmidecode-y
2. Common commands

Motherboard Information: dmidecode | grep-A8 "System Information $"
Memory information: dmidecode | grep-A30 "Memory Device"
Memory slots: dmidecode | grep "Memory Device" | wc-l
4. View hard disk information

1. View hard disk partition information

The command details are as follows:

[Root @ localhost ~] # Fdisk-l
Disk/dev/sda: 1000.2 GB, 1000204886016 bytes
# Specify the disk size of/dev/sda as 1 TB
255 heads, 63 sectors/track, 121601 cylinders
#255 meeting items, 63 sectors, and 121601 Magnetic columns
Units = cylinders of 16065*512 = 8225280 bytes
# The capacity of each magnetic column is 8225280/1024/1024 = 7.85 M
Sector size (logical/physical): 512 bytes/4096 bytes
I/O size (minimum/optimal): 4096 bytes/4096 bytes
Disk identifier: 0x00000000
Device Boot Start End Blocks Id System
/Dev/sda1 1 121602 976762583 + ee GPT
Partition 1 does not start on physical sector boundary.

2. View hard disk partition mounting information

I like to use df-h for details.

[Root @ localhost ~] # Df-h

/Dev/sda4 909 GB 9.9G 853G 2%/
