centos7怎么样修改dns

编辑/etc/NetworkManager/NetworkManager.conf文件

[root@localhost ~]# vim /etc/NetworkManager/NetworkManager.conf

在文件末尾添加dns=none

[main]
#plugins=ifcfg-rh,ibft
dns=none

重启服务

[root@localhost ~]# systemctl restart NetworkManager.service

编辑/etc/resolv.conf文件

[root@localhost ~]# vim /etc/resolv.conf

修改如下：

# Generated by NetworkManager
nameserver 114.114.114.114
nameserver 8.8.8.8
