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 223.5.5.5nameserver 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::1nameserver 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

[root@ecs-kunpeng ~]#使用 dig 验证
若返回结果的 server 为阿里公共 DNS，则配置成功。
[root@ecs-kunpeng ~]# dig alidns.com
