在Linux系统中,有多种方法可以查看CPU和其他硬件配置信息。以下是一些常用的命令:

1. lscpu

lscpu 命令提供了关于CPU架构的详细信息。

lscpu

输出示例:

On-line CPU(s) list:   0-3
Thread(s) per core:    1
Core(s) per socket:    4
Socket(s):             1
NUMA node(s):          1
Vendor ID:             GenuineIntel

2. lshw

lshw 是一个更全面的硬件信息工具,可以显示CPU、内存、磁盘、网络接口等详细信息。

首先需要安装 lshw

sudo apt-get install lshw  # Debian/Ubuntu
sudo yum install lshw      # CentOS/RHEL
sudo dnf install lshw      # Fedora

然后运行:

sudo lshw -short

输出示例:

H/W path         Device     Class          Description
=====================================================
                       system         Computer
                   motherboard  Motherboard    
                       processor    Intel(R) Core(TM) i7-7700HQ CPU @ 2.80GHz
                       memory       16GiB DDR4 Synchronous Unbuffered (Unregistered)
                       memory       16GiB DDR4 Synchronous Unbuffered (Unregistered)
                       storage        SSD SSD
                       storage        HDD HDD
                       network        Wireless LAN
                       network        Ethernet Interface

3. dmidecode

dmidecode 可以提供详细的系统硬件信息,包括BIOS、主板、CPU、内存等。

首先需要安装 dmidecode

sudo apt-get install dmidecode  # Debian/Ubuntu
sudo yum install dmidecode      # CentOS/RHEL
sudo dnf install dmidecode      # Fedora

然后运行:

sudo dmidecode -t processor
sudo dmidecode -t memory
sudo dmidecode -t system

输出示例(部分):

# dmidecode 3.2
Getting SMBIOS data from sysfs.
SMBIOS 2.8 present.
