⤴️ ✍ 📁 `traefik.toml` ⏮️:

```TOML hl_lines="3"
[entryPoints]
  [entryPoints.http]
    address = ":9999"

[providers]
  [providers.file]
    filename = "routes.toml"
```

👉 💬 Traefik 👂 🔛 ⛴ 9️⃣9️⃣9️⃣9️⃣ &amp; ⚙️ ➕1️⃣ 📁 `routes.toml`.

!!! tip

Then create a file `traefik.toml` with:

```TOML hl_lines="3"
[entryPoints]
  [entryPoints.http]
    address = ":9999"

[providers]
  [providers.file]
    filename = "routes.toml"
```

This tells Traefik to listen on port 9999 and to use another file `routes.toml`.

<a href="https://github.com/containous/traefik/releases" class="external-link" target="_blank">下载 Traefik</a>，这是一个二进制文件，需要解压文件，并在 Terminal 中直接运行。

然后创建包含如下内容的 `traefik.toml` 文件：

```TOML hl_lines="3"
[entryPoints]
  [entryPoints.http]
    address = ":9999"

[providers]
  [providers.file]
    filename = "routes.toml"
```

这个文件把 Traefik 监听端口设置为 `9999`，并设置要使用另一个文件 `routes.toml`。
