介绍如何在云上运行
Ray
集群以及如何自动扩展。

手动创建
Ray Cluster

本节介绍手动创建
Ray
集群，你需要有一组可以相互通信并安装了
Ray
的机器

。
首先，你可以选择任何一台机器作为主节点。在该节点上运行以下命令：
ray start --head --port=6379
这个命令将打印启动的
Ray GCS
服务器的
IP
地址，即本地节点的
IP
地址加上
指定的端口号

Next steps
To connect to this Ray runtime from another node, run
ray start --address='<head-address>:6379'
If connection fails, check your firewall settings and network configuration.
你需要这个
<head-address>
将其他节点连接到集群，所以确保复制地址。如果
省略
--port
参数，
Ray
将使用随机端口。
接下来，我们通过在其他各个节点上运行以下命令，将集群中的其他节点连接
到主节点：
ray start --address=<head-address>
确保传递正确的
<head-address>
，它应该类似于
123.45.67.89:6379
。运行此
命令，你应该看到以下形式的输出：
--------------------
Ray runtime started.
