Ubuntu修改DNS重启丢失问题

Ubuntu 15.04直接修改/etc/resolv.conf，添加DNS重启后配置丢失。正确方法：

#vim /etc/network/interfaces，文件最后添加“dns-nameservers 223.5.5.5”重启systemctl restart networking.service，测试OK
#vim /etc/resolvconf/resolv.conf.d/base（文件默认为空）nameserver 223.5.5.5nameserver 223.6.6.6#resolvconf -u （更新改动至resolv.conf）#more /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 OVERWRITTENnameserver 223.5.5.5nameserver 223.6.6.6不需要重启网卡/系统，测试OK，重启系统后OK。
