但 Gunicorn 支持充当 **进程管理器** 并允许用户告诉它要使用哪个特定的 **worker类**。 然后 Gunicorn 将使用该类启动一个或多个 **worker进程**。

**Uvicorn** 有一个 Gunicorn 兼容的worker类。

使用这种组合，Gunicorn 将充当 **进程管理器**，监听 **端口** 和 **IP**。 它会将通信**传输**到运行**Uvicorn类**的worker进程。

然后与Gunicorn兼容的**Uvicorn worker**类将负责将Gunicorn发送的数据转换为ASGI标准以供FastAPI使用。

## 安装 Gunicorn 和 Uvicorn

```console
$ gunicorn main:app --workers 4 --worker-class uvicorn.workers.UvicornWorker --bind 0.0.0.0:80
