第 5 章
生产环境部署
你已经在第
2
章中学会了使用
tar.gz
文件安装
Trino
的方法，并在第
4
章中熟悉了
Trino
的架构，现在可以学习
Trino
集群的安装细节了。有了这些知识，你将能够在生产环境
中部署具有一个协调器和多个工作节点的
Trino
集群。
5.1
配置细节
Trino
的配置由下文所讨论的多个文件所管理，这些文件默认都存放在安装目录下的
etc
目录中。
配置文件目录的默认位置以及各个配置文件的默认位置，都可以使用传给启动脚本的参
数覆盖（参见
5.6
节）。
5.2
服务端配置
Trino
服务端的配置由
etc/config.properties
文件提供。
Trino
服务端可以充当协调器或工
作节点，也可以同时充当两种。每个集群只能有一台协调器。将一台单独的服务端程序
设定为只执行协调器的工作，并添加一系列其他服务端程序作为专用工作节点，这种配
置方式创建
Trino
集群可以提供最佳的性能。
上述配置文件的内容非常重要，特别是因为它们决定了服务端程序是工作节点角色还是
协调器角色，而这相应地会影响资源的使用和配置。
Trino
集群中的所有工作节点应该具有完全相同的配置。
