使用nakama

第一步下载nakama
第二步 docker拉去cockroachDB
第三步运行数据库迁移：nakama.exe migrate up
第四部启动nakama

您可以通过将浏览器导航到127.0.0.1:7351来访问Nakama控制台。

提示登录时，默认凭据为admin:password

可以使用--config标志在运行时指定配置文件。

nakama --config my-special-config.yml

Nakama系统非常灵活。您可以通过gRPC, HTTP, Websockets和rUDP与服务器交换数据。由于这种灵活性，Nakama需要4个端口可用于绑定到：

在端口7350上绑定到HTTP API服务器可以在配置中更改端口。
在7351端口上绑定到HTTP API服务器，这个服务器启动嵌入式开发人员控制台。可以在配置中更改端口。
在端口7349上绑定到gRPC API服务器。根据API服务器端口选择端口。
在7348端口上绑定到gRPC API服务器，该服务器启动嵌入式控制台。根据API服务器端口选择端口。
