Ubuntu 12.04 how to solve the problem of resolv.conf emptying after restart, this article introduces the corresponding analysis and solution in detail, hoping to help more partners who want to solve this problem to find a more simple and feasible method.

This is completely different from the previous RHT system:

I searched google and found that there was some mystery in it:

1 / etc/resolv.conf is actually a Link

It actually points to / run/resolvconf/resolv.conf.

2 Ubuntu has a resolvconf service. If you restart it, the content of / etc/resolv.conf will be changed to the default.

So you can't modify / etc/resolv.conf directly.

3 if you want to define nameserver yourself, there are two ways to do it:

An add to the configuration file of the network card:

Iface eth0 inet static

Address 192.168.3.3

Netmask 255.255.255.0

Gateway 192.168.3.1

Dns-nameservers 192.168.3.45 192.168.8.10

Dns-search foo.org bar.com

B modify the configuration file of the resolvconf service: / etc/resolvconf/resolv.conf.d/base

In this way, both the restart of the machine or the restart of the resolvconf service can guarantee that the configuration will be written to / etc/resolv.conf

In fact, there are hints all the time in / etc/resolv.conf, but I didn't pay attention to it:

"DO NOT EDIT THIS FILE BY HAND-YOUR CHANGES WILL BE OVERWRITTEN"

For more information about resolvconf services, you can use man to see: man resolvconf

For the time being, I haven't found a command that can directly refresh / etc/resolv.conf content. I can only restart the resolvconf service.

This is the answer to the question about Ubuntu 12.04 how to solve the problem of resolv.conf emptying after restart. I hope the above content can be of some help to you. If you still have a lot of doubts to be solved, you can follow the industry information channel for more related knowledge.
