Linux 系统配置信息查询 各种查看Linux配置的方法

查看CPU信息

cat /proc/cpuinfo

可以看到CPU是Intel® Core™ i7-10870H CPU @ 2.20GHz 16线程的

查看内存大小

free

可以看到是分配了16298864KB的内存 也就是16G左右 使用top也可以查看

按Shift + E可以切换显示单位

查看系统版本

RetHat系的可以使用,比如CentOS

cat /etc/redhat-release

这个命令在Ubuntu就失效了 Ubuntu可以使用 lsb_release -a 或者 cat /etc/issue

查看系统内核版本

使用

cat /proc/version

查看网卡信息

使用lspci会列出全部的pci设备 通过grep过滤出网卡信息

lspci |grep -i 'eth'

查看主板信息

dmidecode

这个命令会列出主板SMBIOS的各种详细信息,但虚机可能查看不了什么信息

# dmidecode 3.1
