抛弃ADguardhome轻松搭建无污染dns及ui显示界面，预防DNS泄漏

我之前是通过旁路由打开mosdns做dns解析及分流，但是我平时经常爱折腾加上openwrt插件太多兼容性问题，导致openwrt经常挂掉，然后家里就断网了。

所以一个稳定且强大的DNS服务器无疑是家庭网络中不可缺少的一环。

因此，我为您准备了一篇详细的指南，搭建一个独立的dns服务器及ui显示界面，从而提高网络的稳定性和响应速度。

项目介绍

mosdns：一个 DNS 转发器

项目地址：https://github.com/IrineSistiana/mosdns

easymosdns：基于Mosdns的精准DNS分流策略，仅需几分钟即可搭建一台支持ECS的无污染DNS服务器。

https://github.com/pmkol/easymosdns

Prometheus：是云原生计算基金会项目，是一个系统和服务监控系统

项目地址：https://github.com/prometheus/prometheus

grafana：用于监控和可观察的开源平台

项目地址：https://github.com/grafana/grafana

exsi安装debian12系统

网上有保姆级教程，我这里就不介绍了。

固定ip地址

nano /etc/network/interfaces

把网卡的dhcp改成static，address是ip地址，netmask是子网掩码，gateway是网关

iface ens192 inet static
address 10.0.0.222
netmask 255.255.255.0
gateway 10.0.0.1
dns-nameservers 127.0.0.1
iface ens192 inet6 dhcp

更完玩重启服务器，随后用ssh通过修改完的ip地址登录

reboot

easymosdns安装步骤

首先，我们需要安装easymosdns。

我会把脚本打包放在文章底部。

该过程简洁明了，只需遵循以下几个步骤：

上传脚本dns-ui到root目录下

抛弃ADguardhome轻松搭建无污染dns及ui显示界面，预防DNS泄漏

脚本权限修改

首先，为安装脚本授予可执行权限：

chmod +x dns-ui.sh

执行安装脚本

然后，执行脚本以启动安装过程：

./dns-ui.sh

脚本中包含了常用的组件以及docker等

配置文件的调整

进入mosdns程序目录

cd /etc/mosdns

删掉原本mosdns的config文件，替换目录下的config1.yml

rm config.yaml
mv config1.yaml config.yaml

如果自己会用mosdns也可根据您的需求调整配置文件的内容。

重启easymosdns服务

应用配置后重启服务以确保更改生效：

mosdns service restart

确认安装成功

最后，检查服务状态以验证安装是否成功：

mosdns service status

至此mosdns的安装已完成

安装grafana和Prometheus

创建启动文件的配置

接下来我们需要创建并配置启动文件：

mkdir -p /home/docker/prometheus/

之后，将先前下载好的prometheus.yml文件移至此配置文件夹内。

抛弃ADguardhome轻松搭建无污染dns及ui显示界面，预防DNS泄漏
# prometheus.yml

global:
  scrape_interval:     15s # Set the scrape interval to every 15 seconds. Default is every 1 minute.
  evaluation_interval: 15s # Evaluate rules every 15 seconds. The default is every 1 minute.
  # scrape_timeout is set to the global default (10s).

  # Attach these labels to any time series or alerts when communicating with
  # external systems (federation, remote storage, Alertmanager).
  external_labels:
      monitor: 'example'

# Alertmanager configuration
alerting:
  alertmanagers:
  - static_configs:
    - targets: ['localhost:9093']

# Load rules once and periodically evaluate them according to the global 'evaluation_interval'.
rule_files:
  # - "first_rules.yml"
  # - "second_rules.yml"

# A scrape configuration containing exactly one endpoint to scrape:
# Here it's Prometheus itself.
scrape_configs:
  # The job name is added as a label `job=<job_name>` to any timeseries scraped from this config.
  - job_name: 'prometheus'

    # Override the global default and scrape targets from this job every 5 seconds.
    scrape_interval: 5s
    scrape_timeout: 5s

    # metrics_path defaults to '/metrics'
    # scheme defaults to 'http'.

    static_configs:
      - targets: ['localhost:9090']

  - job_name: node
    # If prometheus-node-exporter is installed, grab stats about the local
    # machine by default.
    static_configs:
      - targets: ['localhost:9100']

  - job_name: mosdns
    static_configs:
      - targets: ['localhost:9080']

进入docker文件夹下

cd /home/docker

上传docker-compose.yml文件

抛弃ADguardhome轻松搭建无污染dns及ui显示界面，预防DNS泄漏
# docker-compose.yml
version: '3'
services:
  grafana:
    image: grafana/grafana-oss:latest
    container_name: grafana
    restart: always
    user: root
    network_mode: host
    volumes:
      - /home/docker/grafana/data:/var/lib/grafana
      - /home/docker/grafana/panels:/etc/dashboards
      - /home/docker/grafana/provisioning/dashboards:/etc/grafana/provisioning/dashboards
      - /home/docker/grafana/provisioning/datasources:/etc/grafana/provisioning/datasources
  prometheus:
    image: prom/prometheus
    container_name: prometheus
    hostname: prometheus
    restart: always
    user: root
    network_mode: host
    volumes:
      - /home/docker/prometheus/prometheus.yml:/etc/prometheus/prometheus.yml

Docker安装相关文件

docker-compose up -d

可通过一下命令查看docker容器是否已运行

docker ps

可视化配置步骤

Grafana软件配置

以Grafana为例，我们可以进行如下几步配置来优化您的可视化体验：

修改默认数据库地址
打开Grafana，将默认数据库地址更改为：

http://localhost:9090

修改默认语言
根据您的偏好，调整界面语言设置。

日志文件优化

为了保持系统的整洁和高效运行，我们可以通过定期清理日志文件来优化性能：

crontab -e

在文件末尾添加以下内容，以定时清理DNS服务的日志文件：

0 5 * * * sudo truncate -s 0 /etc/mosdns/mosdns.log && /etc/mosdns/rules/update-cdn

通过上述步骤，您不仅可以减少家庭网络中的断网情况，还能获得一个更加稳定、高效的DNS服务。

如何使用DNS服务器

家里想使用dns服务器的可以网关指向这个服务器的ip地址

如果想整个网络环境都是用，那可以主路由套娃的形式指向这个dns服务器
