Linux——查看系统硬件信息

柔情只为你懂 2022-01-26 11:57 478阅读 0赞

前言：下面实验的信息是我在几台配置不同服 务器的测试结果，操作系统分别为Red Hat Enterprise Linux Server release 6.0 (Santiago)、Ubuntu 7.10。所以你看到我实验信息的不同时，请不要大惊小怪。而且有些命令也不是所有Linux操作系统都支持（例如在Ubuntu 7.10就不支持dmesg），下面的内容是收集整理的，如有错误或新的方法，也会不停整理、更新。

一：查看CPU信息

1、CPU详细信息

方法1：CPU信息一般保存在proc目录下的cpuinfo文件中。如下所示。

[root@DB-Server ~]# more /proc/cpuinfo

方法2：使用dmesg命令（注意CPU应为大写）

[root@m1 ~]$dmesg | grep CPU

    processor LNXCPU:01: registered as cooling_device1
    
    processor LNXCPU:02: registered as cooling_device2

方法3：使用dmidecode查看CPU信息

[root@DB-Server ~]# dmidecode -t processor
    
    # dmidecode 2.10
    
    SMBIOS 2.4 present.

2、查看物理CPU个数

3、查看逻辑CPU个数

4、查看CPU是几核的

[root@DB-Server ~]# cat /proc/cpuinfo | grep "cores" | uniq
    
    cpu cores : 3

5、查看CPU的主频

[root@DB-Server ~]# cat /proc/cpuinfo | grep MHz | uniq
    
    cpu MHz : 800.000
    
    [root@DB-Server ~]# cat /proc/cpuinfo | grep MHz
    
    cpu MHz : 800.000
    
    cpu MHz : 800.000
    
    cpu MHz : 800.000

6、查看CPU型号信息

[root@DB-Server ~]# cat /proc/cpuinfo | grep name | cut -f2 -d: | uniq -c
    
    3 AMD Athlon(tm) II X3 450 Processor

7、通过physical id 可以判断物理CPU个数

[root@DB-Server ~]# cat /proc/cpuinfo | grep physical | uniq -c
    physical id : 0
    address sizes : 48 bits physical, 48 bits virtual
    physical id : 0
    address sizes : 48 bits physical, 48 bits virtual
    physical id : 0
    address sizes : 48 bits physical, 48 bits virtual

8、查看CPU是否支持64位运算

[root@DB-Server ~]# cat /proc/cpuinfo | grep flags | grep 'lm' | wc -l
    
    3
    
    结果大于0，说明支持64位运算，lm指long mode 支持lm则是64bit

[root@DB-Server ~]# getconf LONG_BIT
    
    etl:/home/etl/$getconf LONG_BIT（另外一台服务器）
    
    说明当前CPU运行在32位模式下，当不代表CPU不支持64位

二、 查看内存信息

四：查看网卡信息

1. mii-tool 指令来查看网卡信息。它主要是用于配置网卡工作模式的指令，同时也可以用于查询、监控工作。

2. 直接输入dmesg可以看到开机检测到硬件信息

3. ethtool eth0 采用此命令查到网卡相关的技术指标 (不一定所有网卡支持都支持此命令)

4. more /etc/sysconfig/network-scripts/ifcfg-eth0 用这个可以看到网卡的信息

5. ifconfig

6. lspci

网卡配置文件

每一个网络介质都对应一个配置文件，超级用户可以通过这些配置文件来配置网卡

网卡配置文件存放在/etc/sysconfig/network-scripts/目录中

/etc/sysconfig/network-scripts/ifcfg-interface-name

设置文件ifcfg-interface-name包含了初始化接口所需的大部分周详信息，其中interface-name将根据网卡的类型和排序而不同，一般其名字为eth0、eth1、ppp0等，

其中eth表示以太(eth0)类型网卡，0表示第一块网卡、1表示第二块网卡，而ppp0则表示point-to-poirt protocol网络接口。在ifcfg文件中定义的各项目取决于接口类型。

DEVICE=name 其中name是物理设备名

IPADDR=addr 其中addr是IP地址

NETMASK=mask 其中mask是网络掩码值

NETWORK=addr 其中addr是网络地址

BROADCAST=addr 其中addr是广播地址

GATEWAY=addr 其中addr是网关地址

ONBOOT=answer 其中answer是yes(引导时激活设备)或no（引导时不激活设备）

USECTL=answer 其中answer是yes（非root用户能控制该设备）或no

BOOTPROTO=proto
