|
> 容器化的无污染DNS服务,同时兼具广告拦截与防跟踪功能
|
|
|
|
|
|
|
|
ClearDNS基于Docker容器运行,用于提供纯净的DNS服务,避开运营商与防火长城的DNS污染与劫持,连接到路由器的内网设备无需任何改动即可使用,它还会记录所有解析请求,用于查询哪些设备都访问了哪些域名。
|
|
|
|
|
|
|
|
ClearDNS可以在DNS层面上实现去广告与防跟踪功能,按需求配置自定义的拦截规则,无论APP、网页还是机顶盒、IoT设备等,只要接入到同个网络下均有效。同时兼具强制host功能,将指定域名直接解析到指定IP上,也可用于屏蔽特定的应用,如QQ、微信、微博等。
|
|
|
|
|
|
|
|
ClearDNS可部署在主路由器上,但需要路由器刷入支持Docker的固件;对于性能较低或不支持刷机的路由器,建议部署在内网一台长期开机的设备上(树莓派、小主机、旁路由等)。

## 部署教程
|
|
|
|
|
|
|
|
### 1. 网络配置
|
|
|
|
|
|
|
|
ClearDNS基于Docker网络有以下三种部署模式:
|
|
|
|
|
|
|
|
| | host模式 | bridge模式 | macvlan模式 |
|
|
|
|
| :-: | :-: | :-: | :-: |
|
|
|
|
| 网络原理 | 宿主机网络 | 桥接网络 | 虚拟独立mac网卡 |
|
|
|
|
| 服务IP | 宿主机IP | 宿主机IP | 容器独立IP |
|
|
|
|
| 宿主机IP | 静态IP地址 | 静态IP地址 | 静态/动态IP地址 |
|
|
|
|
| 宿主机网络 | 无需改动网络配置 | Docker自动适配 | 手动修改底层网络配置 |
|
|
|
|
| 宿主机端口 | 占用宿主机53,80,4053,5353,6053端口 | 占用宿主机53与80端口 | 不占用端口 |
|
|
|
|
| 管理完整性 | 完全 | 无法区分客户端 | 完全 |
|
|
|
|
| 宿主机耦合 | 强耦合 | 一般耦合 | 链路层以上完全分离 |
|
|
|
|
| 网络性能 | 相对较高 | 相对较低 | 相对适中 |
|
|
|
|
| 部署难度 | 简单 | 简单 | 复杂 |
|
|
|
|
|
|
|
|
> 不熟悉Linux网络配置请勿使用macvlan模式,新手建议首选host模式。
|
|
|
|
|
|
|
|
以下操作均于root用户下执行
|
|
|
|
|
|
|
|
```
|
|
|
|
# 检查Docker环境
|
|
|
|
shell> docker --version
|
|
|
|
Docker version ···, build ···
|
|
|
|
|
|
|
|
# 无Docker环境请先执行安装
|
|
|
|
shell> wget -qO- https://get.docker.com/ | bash
|
|
|
|
```
|
|
|
|
|
|
|
|
ClearDNS可以从多个镜像源获取,其数据完全相同,国内用户建议首选阿里云镜像。
|
|
|
|
|
|
|
|
```
|
|
|
|

|
# ClearDNS会将数据持久化,以在重启Docker或宿主机后保留配置及日志
|
|
|
|
# 使用以下命令清除之前的ClearDNS配置及数据
|
|
|
|
shell> rm -rf /etc/cleardns
|
|
|
|
```
|
|
|
|
|
|
|
|
### 2. 指定上游DNS服务器
|
|
|
|
|
|
|
|
上游DNS信息位于 `/etc/cleardns/upstream.json`,分为国内外两组,国内组可指定阿里DNS、DNSPod、114DNS等国内公共DNS服务,国外组需要指定可用的加密DNS服务,建议自行搭建DoH或DoT服务器。
|
|
|
|
|
|
|
|
ClearDNS支持多种[DNS服务协议](https://blog.dnomd343.top/dns-server/#DNS%E5%90%84%E5%8D%8F%E8%AE%AE%E7%AE%80%E4%BB%8B),包括常规DNS、DNS-over-TLS、DNS-over-HTTPS、DNS-over-QUIC、DNSCrypt。
|
|
|
|
|
|
|
|
> DNSCrypt使用DNS Stamp封装,可以在[这里](https://dnscrypt.info/stamps)在线解析或生成链接内容。
|
|
|
|
|
|
|
|
各协议格式示例如下:
|
|
|
|
|
|
|
|
```
|
|
|
|
# Plain DNS
|
|
|
|
1.1.1.1
|
|
|
|
8.8.8.8
|
|
|
|
|
|
|
|
# DNS-over-TLS
|
|
|
|
tls://223.5.5.5
|
|
|
|
tls://dns.alidns.com
|
|
|
|
|
|
|
|
# DNS-over-HTTPS
|
|
|
|
https://dns.pub/dns-query
|
|
|
|
https://223.5.5.5/dns-query
|
|
|
|
|
|
|
|
# DNS-over-QUIC
|
|
|
|
quic://dns.adguard.com
|
|
|
|
|
|
|
|
# DNSCrypt
|
|
|
|
sdns://AQIAAAAAAAAAFDE3Ni4xMDMuMTMwLjEzMDo1NDQzINErR_JS3PLCu_iZEIbq95zkSV2LFsigxDIuUso_OQhzIjIuZG5zY3J5cHQuZGVmYXVsdC5uczEuYWRndWFyZC5jb20
|
|
|
|
```
|
|
|
|
|
|
|
|
ClearDNS默认配置了以下DNS服务器
|
|
|
|
|
|
|
|
```
|
|
|
|
# 此处指定的国外组服务器可能已被GFW屏蔽,强烈建议使用私有加密DNS服务器
|
|
|
|
# bootstrap指定DNS服务器IP地址,用于解析加密DNS服务器域名,省略时使用系统DNS
|
|
|
|
# 若指定多台服务器,DNS请求时将并发查询,因此不宜指定过多服务器
|
|
|
|
# 当primary中DNS均不可用时,将自动尝试fallback中的DNS地址
|
|
|
|

|
|
|
|

],
|
|
|
|
"fallback": [
|
|
|
|
"1.1.1.1",
|
|
|
|
"8.8.8.8"
|
|
|
|
]
|
|
|
|
}
|
|
|
|
}
|
|
|
|
```
|
|
|
|
|
|
|
|
重启Docker容器生效
|
|
|
|
|
|
|
|
```
|
|
|
|
shell> docker restart cleardns
|
|
|
|
```
|
|
|
|
|
|
|
|
### 3. 配置域名分流规则
|
|
|
|
|
|
|
|
ClearDNS依据规则列表分流解析,使用以下规则文件,位于文件夹 `/etc/cleardns/asset` 中
|
|
|
|
|
|
|
|
+ [`china-ip.txt`](https://res.343.re/Share/chinalist/china-ip.txt):国内IP段
|
|
|
|
|
|
|
|
+ [`chinalist.txt`](https://res.343.re/Share/chinalist/chinalist.txt):国内常见域名
|
|
|
|
|
|
|
|
+ [`gfwlist.txt`](https://res.343.re/Share/gfwlist/gfwlist.txt):被GFW屏蔽的常见域名
|
|
|
|
|
|
|
|
以上文件将在每天凌晨4点自动更新,如果不想启用该功能,创建 `/etc/cleardns/asset/no-update` 文件即可。
|
|
|
|
|
|
|
|
规则文件默认从 `res.dnomd343.top` 拉取,若该域名被污染或屏蔽,你可以使用本项目 `asset/gfwlist/build` 与 `asset/chinalist/build` 下的构建脚本自行生成规则列表。
|
|
|
|
|
|
|
|
> 构建脚本需要访问Github获取资源,手动构建时请注意网络连通性。
|
|
|
|
|
|
|
|
### 4. 配置AdGuardHome
|
|
|
|
|
|
|
|
浏览器打开ClearDNS服务,host与bridge模式输入宿主机IP地址,macvlan模式输入容器IP,进入AdGuardHome配置界面,设置账号和密码,登录进入AdGuardHome管理界面。
|
|
|
|
|
|
|
|
进入 `设置` - `DNS设置`,修改上游DNS为 `127.0.0.1:5353`,其他选项保持默认。此外,下方其他设置中建议启用DNSSEC,内存允许的情况下适当拉大缓存大小,并开启乐观缓存。
|
|
|
|
|
|
|
|
DNS封锁清单中,可配置以下规则:
|
|
|
|
|
|
|
|
+ `AdGuard`:`https://adguardteam.github.io/AdGuardSDNSFilter/Filters/filter.txt`
|
|
|
|
|
|
|
|
+ `Anti-AD`:`https://anti-ad.net/easylist.txt`
|
|
|
|
|
|
|
|
+ `AdAway`:`https://adaway.org/hosts.txt`
|
|
|
|
|
|
|
|
+ `乘风规则`:`https://res.343.re/Share/Adblock-Rules/xinggsf.txt`
|
|
|
|
|
|
|
|
> 配置过多的规则会导致设备负载变大,请酌情添加。
|
|
|
|
|
|
|
|
### 5. 配置DHCP信息
|
|
|
|
|
|
|
|
为了使ClearDNS生效,需要在路由器DHCP服务中指定DNS服务器,host与bridge模式指定为宿主机IP,macvlan模式指定为容器IP。
|
|
|
|
|
|
|
|
> 对于内网中一些固定IP信息的设备,需要手动更改其DNS为上述IP地址。
|
|
|
|
