【阿里云镜像】使用阿里巴巴DNS镜像源——DNS配置教程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 NetworkManagersearch openstacklocal#nameserver 100.125.1.250#nameserver 100.125.129.250options timeout:1 single-request-reopennameserver 223.5.5.5nameserver 223.6.6.6[root@ecs-kunpeng ~]#

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 NetworkManagersearch openstacklocal#nameserver 100.125.1.250#nameserver 100.125.129.250options timeout:1 single-request-reopennameserver 223.5.5.5nameserver 223.6.6.6nameserver 2400:3200::1nameserver 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 digbind-utils-32:9.11.26-4.el8_4.aarch64 : Utilities for querying DNS name serversRepo        : AppStreamMatched from:Filename    : /usr/bin/dig
