Als Nächstes würden Sie den Server ausführen und die Konfigurationen als Umgebungsvariablen übergeben. Sie könnten beispielsweise `ADMIN_EMAIL` und `APP_NAME` festlegen mit:

<div class="termy">

```console
$ ADMIN_EMAIL="deadpool@example.com" APP_NAME="ChimichangApp" uvicorn main:app

<span style="color: green;">INFO</span>:     Uvicorn running on http://127.0.0.1:8000 (Press CTRL+C to quit)
```

</div>

/// tip | "Tipp"

<div class="termy">

```console
$ ADMIN_EMAIL="deadpool@example.com" APP_NAME="ChimichangApp" uvicorn main:app

<span style="color: green;">INFO</span>:     Uvicorn running on http://127.0.0.1:8000 (Press CTRL+C to quit)
```

</div>

/// tip

⚒ 💗 🇨🇻 {👁 📋 🎏 👫 ⏮️ 🚀, &amp; 🚮 👫 🌐 ⏭ 📋.

///

&amp; ⤴️ `admin_email` ⚒ 🔜 ⚒ `"deadpool@example.com"`.

`app_name` 🔜 `"ChimichangApp"`.

Next, you would run the server passing the configurations as environment variables, for example you could set an `ADMIN_EMAIL` and `APP_NAME` with:

<div class="termy">

```console
$ ADMIN_EMAIL="deadpool@example.com" APP_NAME="ChimichangApp" fastapi run main.py

<span style="color: green;">INFO</span>:     Uvicorn running on http://127.0.0.1:8000 (Press CTRL+C to quit)
```

</div>

/// tip

<div class="termy">

```console
$ ADMIN_EMAIL="deadpool@example.com" APP_NAME="ChimichangApp" fastapi run main.py

<span style="color: green;">INFO</span>:     Uvicorn running on http://127.0.0.1:8000 (Press CTRL+C to quit)
```

</div>

/// dica

<div class="termy">

```console
$ ADMIN_EMAIL="deadpool@example.com" APP_NAME="ChimichangApp"uvicorn main:app

<span style="color: green;">INFO</span>:     Uvicorn running on http://127.0.0.1:8000 (Press CTRL+C to quit)
```

</div>

/// tip

要为单个命令设置多个环境变量，只需用空格分隔它们，并将它们全部放在命令之前。

///

然后，`admin_email` 设置将为 `"deadpool@example.com"`。

`app_name` 将为 `"ChimichangApp"`。
