linux查看服務器dns配置

查看dns配置：

[root@ecs-a3b8-0206438 ~]# cat /etc/resolv.conf 
# Generated by NetworkManager
search openstacklocal novalocal
nameserver 100.125.108.250
nameserver 202.98.192.67
[root@ecs-a3b8-0206438 ~]#

有時爲了防止dns解析不暢，提升網絡性能，我們可以更改爲如下配置：

[root@kznginx01 ~]# cat /etc/resolv.conf 
# Generated by NetworkManager
search 8.8.8.8
nameserver 114.114.114.114
[root@kznginx01 ~]#
