二、DNS简介三、配置方法 Linux 快速配置ipv4编辑文件 " /etc/resolv.conf" ，根据情况修改文件内容。
只需要添加以下两行
nameserver 223.5.5.5
nameserver 223.6.6.6

[root@ecs-kunpeng ~]# vim /etc/resolv.conf [root@ecs-kunpeng ~]# cat /etc/resolv.conf # Generated by NetworkManager search openstacklocal #nameserver 100.125.1.250 #nameserver 100.125.129.250 options timeout:1 single-request-reopen nameserver 223.5.5.5 nameserver 223.6.6.6 [root@ecs-kunpeng ~]#

Linux 快速配置ipv6编辑文件 " /etc/resolv.conf" ，根据情况修改文件内容。
只需要添加以下两行
nameserver 2400:3200::1
nameserver 2400:3200:baba::1

[root@ecs-kunpeng ~]# vim /etc/resolv.conf [root@ecs-kunpeng ~]# cat /etc/resolv.conf # Generated by NetworkManager search openstacklocal #nameserver 100.125.1.250 #nameserver 100.125.129.250 options timeout:1 single-request-reopen nameserver 223.5.5.5 nameserver 223.6.6.6 nameserver 2400:3200::1 nameserver 2400:3200:baba::1

保存退出，然后使用 dig 验证：
若显示以下错误信息

[root@ecs-kunpeng ~]# dig alidns.com -bash: dig: command not found [root@ecs-kunpeng ~]# [root@ecs-kunpeng ~]# yum provides dig bind-utils-32:9.11.26-4.el8_4.aarch64 : Utilities for querying DNS name servers Repo: AppStream Matched from: Filename: /usr/bin/dig

使用yum源安装bind-utils-32:9.11.26-4.el8_4.aarch64组件

使用 dig 验证若返回结果的 server 为阿里公共 DNS，则配置成功。
