dnsmasq itself is not altering resolv.conf
If you have your configuration file and start it manually via <code>dnsmasq -d -C &lt;yourconfig&gt;</code> you see that.
This behaviour comes from systemd unit on debian and probably on ubuntu systems and perhaps on other distributions.
Stop dnsmasq via <code>sudo systemctl stop dnsmasq</code> (because otherwise changed /etc/resolv.conf won't be restored)
edit <code>/etc/systemd/system/multi-user.target.wants/dnsmasq.service</code>
and comment out both lines
<pre><code>#ExecStartPost=/etc/init.d/dnsmasq systemd-start-resolvconf
#ExecStop=/etc/init.d/dnsmasq systemd-stop-resolvconf
</code></pre>
exec <code>sudo systemctl daemon-reload</code>
after that you can start dnsmasq and your /etc/resolv.conf file won't be changed by dnsmasq

blocks|key|963096|text|您可以让dnsmasq使用不同的resolv.conf文件，所以当/etc/resolv.conf指向127.0.0.1时，dnsmasq实际上只使用其他resolv.conf文件，而不使用/etc/resolv.conf。|type|unstyled|depth|inlineStyleRanges|offset|length|style|CODE|entityRanges|data|963097|将以下行添加到dnsmasq.conf文件中：|963098|resolv-file=/etc/dnsmasq.d/dnsmasq-resolv.conf|code-block|syntax|javascript|963099|然后创建文件/etc/dnsmasq.d/dnsmasq-resolv.conf，如下所示：|963100|nameserver+208.67.222.222

You can have <code>dnsmasq</code> use a different <code>resolv.conf</code> file, so when <code>/etc/resolv.conf</code> points to 127.0.0.1, <code>dnsmasq</code> will actually just use the other <code>resolv.conf</code> file and leave <code>/etc/resolv.conf</code> alone. 

Add the following line to your <code>dnsmasq.conf</code> file: 

<pre><code>resolv-file=/etc/dnsmasq.d/dnsmasq-resolv.conf
</code></pre>

And then create the file <code>/etc/dnsmasq.d/dnsmasq-resolv.conf</code> to look something like this: 

<pre><code>nameserver 208.67.222.222
nameserver 208.67.220.220
</code></pre>

The machine won't be able to get the DNS server address(es) via DHCP, but it solves the problem.

blocks|key|3562406|text|我也有过同样的问题。在debian斗牛眼上，当安装了case+(默认情况下是这样，如果我没有弄错)时，dnsmasq就会有这种行为。您应该编辑/etc/default/dsnmasq文件并取消对这一行的注释：|type|unstyled|depth|inlineStyleRanges|offset|length|style|CODE|entityRanges|data|3562407|#+If+the+resolvconf+package+is+installed,+dnsmasq+will+tell+resolvconf

I had the same issue. On debian bullseye, when resolvconf is installed (which is the case by default, if I am not mistaken) then dnsmasq will have this behavior. You should edit the <code>/etc/default/dsnmasq</code> file and uncomment this line:
<pre><code># If the resolvconf package is installed, dnsmasq will tell resolvconf
# to use dnsmasq under 127.0.0.1 as the system's default resolver.
# Uncommenting this line inhibits this behaviour.
#DNSMASQ_EXCEPT=&quot;lo&quot;
</code></pre>
into
<pre><code># If the resolvconf package is installed, dnsmasq will tell resolvconf
# to use dnsmasq under 127.0.0.1 as the system's default resolver.
# Uncommenting this line inhibits this behaviour.
DNSMASQ_EXCEPT=&quot;lo&quot;
</code></pre>
It worked for me.

Every time I (re)start dnsmasq it replaces <code>/etc/resolv.conf</code> with <code>nameserver 127.0.0.1 ...</code>.

However that maschine has not to use the local DNS service. (Please don't ask why, the whole environment is like it is...)

How do I actually prevent dnsmasq from touching <code>/etc/resolv.conf</code>?

Neither removing <code>resolvconf</code> nor <code>chattr +i /etc/resolv.conf</code> is an option.

Make dnsmasq not altering resolv.conf

每次我(重新)启动dnsmasq时，它都将/etc/resolv.conf替换为nameserver 127.0.0.1 ...。但是，maschine不需要使用本地DNS服务。(请不要问为什么，整个环境就像.)我怎样才能真正防止/etc/resolv.conf接触？删除resolvconf或chattr +i /etc/resolv.conf都不是一种选择。
