Ubuntu 能ping通DNS 地址 无法解析域名

 

ping通qq百度都行,唯独谷歌不行,

主机能够ping通google的dns服务器地址 8.8.8.8,却无法解析域名

 
$ ping www.google.co.uk
ping: unknown host www.google.co.uk

 

查看/etc/network/interfaces文件写的有 dns-nameservers 8.8.8.8 8.8.4.4 这句,再查看/etc/resolv.conf 文件,

 
$  cat /etc/resolv.conf
# Dynamic resolv.conf(5) file for glibc resolver(3) generated by resolvconf(8)
#     DO NOT EDIT THIS FILE BY HAND -- YOUR CHANGES WILL BE OVERWRITTEN

 

增加

 
nameserver 8.8.8.8
nameserver 8.8.4.4

 

重启网卡,发现还是不行,再看这个文件,nameserver的配置又不见了。
又查了下资料,发现/etc/resolv.conf 每次都要重写,需要更改

/etc/resolvconf/resolv.conf.d/head

 

在这个文件末尾增加nameserver 配置

 
# Dynamic resolv.conf(5) file for glibc resolver(3) generated by resolvconf(8)
#     DO NOT EDIT THIS FILE BY HAND -- YOUR CHANGES WILL BE OVERWRITTEN
nameserver 8.8.8.8
nameserver 8.8.4.4

 

重启网卡就好了

BTW, 我在CentOS7.1也碰到同样的情况,Ping 8.8.8.8可以,不能解析。
错误提示: failed to start lsb bring up/down networking。 通过以下操作解决了问题:

systemctl stop NetworkManager
systemctl disable NetworkManager
Reboot
。。。。。。
systemctl start NetworkManager
systemctl enable NetworkManager
