树莓派修改 DNS 服务器配置-CFANZ编程社区

修改配置文件

1	sudo vim /etc/dhcpcd.conf

增加如下内容，我们使用Google DNS（北京联通测试速度不错）

1	static domain_name_servers=8.8.8.8 8.8.4.4

完整的示例文件部分

1 2 3 4	interface eth0 ip_address=192.168.1.3/24 routers=192.168.1.1 domain_name_servers=8.8.8.8 8.8.4.4

设置配置生效

1	sudo service dhcpcd restart

验证是否生效

我们使用dig命令验证dns是否生效

注意

不要直接修改这个文件/etc/resolv.conf

正如上面英文说得，这个文件会被冲掉，未来某个时间你还需要重新设置。所以按照文章中的修改即可。
