Ubuntu修改DNS重新啟動丟失問題

2020-06-16 17:48:03

Ubuntu 15.04直接修改/etc/resolv.conf，新增DNS重新啟動後設定丟失。

正確方法：

#vim /etc/network/interfaces，檔案最後新增“dns-nameservers 223.5.5.5”

重新啟動systemctl restart networking.service，測試OK
#vim /etc/resolvconf/resolv.conf.d/base（檔案預設為空）

nameserver 223.5.5.5

nameserver 223.6.6.6

#resolvconf -u (更新改動至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 OVERWRITTEN

nameserver 223.5.5.5

nameserver 223.6.6.6

不需要重新啟動網絡卡/系統，測試OK，重新啟動系統後OK。
