可以修改 ip 地址
```shell
sudo sqlite3   /root/program/headscale/headscale/data/db.sqlite
# sudo sqlite3 /home/mrh/program/headscale/headscale/data/db.sqlite
SELECT id, hostname, ipv4 FROM nodes;
UPDATE nodes SET ipv4 = "100.64.0.31" WHERE hostname="vs1";
UPDATE nodes SET ipv4 = "100.64.0.32" WHERE hostname="sv-v2";
UPDATE nodes SET ipv4 = "100.64.0.33" WHERE hostname="s2";
UPDATE nodes SET ipv4 = "100.64.0.12" WHERE hostname="pc";
# 更新完后，不需要做额外操作，各个节点会自动更新
```
## 其他操作系统

### Windows 
https://headscale.net/stable/usage/connect/windows/

安装好之后，打开 cmd 控制台：
```shell
tailscale up --login-server https://hs.magong.site  --authkey 90e2d5089997c0ef0929eaa8475ac441de0fe9acae43cfbd  --accept-dns=true
```

### 安卓
教程： https://headscale.net/stable/usage/connect/android/

下载： https://github.com/tailscale/tailscale-android

下载 APK 包后，
- 打开应用程序，选择右上角的设置菜单
- 点击 Account 
- 在右上角的菜单图标（三个点）中，选择使用备用服务器 Use an alternate server
- 输入您的服务器URL https://hs.magong.site  ，输入完成后不会有任何提示，不要紧
- 再次右上角的菜单图标（三个点）中，选择使用认证密钥 Use an auth key
- 输入您的认证密钥 90e2d5089997c0ef0929eaa8475ac441de0fe9acae43cfbd ，输入完成后不会有任何提示。一般到这里，返回主页即可连接成功
小米的默认域名是 localhost，不想使用这个域名，可以到服务器修改：
```shell
ssh root@dy1
sudo sqlite3   /root/program/headscale/headscale/data/db.sqlite
SELECT id, hostname, ipv4 FROM nodes;
UPDATE nodes SET hostname = "mi11" WHERE id=12;

```

## MagicDNS 
```shell
ssh root@dy1
vi /root/program/headscale/headscale/data/extra-records.json
```
```json
[
    {
      "name": "dify.sv-v2.lan",
      "type": "A",
      "value": "100.64.0.32"
    }
  ]
```
```shell
vi /root/program/headscale/headscale/config/config.yaml
# extra_records_path: 
exit 
sudo vi /home/mrh/program/headscale/app/caddy-lan/lan.Caddyfile
dk exec caddy-lan caddy reload -c /etc/caddy/Caddyfile
dk exec caddy-lan  caddy fmt --overwrite /etc/caddy/Caddyfile
```


### 云服务器冲突的问题

https://sh.alynx.one/posts/Who-Moved-My-DNS-Resolving/
```shell
# 建议指定为云服务器的内网 DNS 服务器
sudo resolvectl domain eth0 ~.

# 下述实测未解决
sudo ln -sf /run/systemd/resolve/stub-resolv.conf /etc/resolv.conf
sudo apt-get install network-manager
systemctl enable NetworkManager
systemctl restart NetworkManager
systemctl status NetworkManager
ping mirrors.ivolces.com
