注意适用于工作节点的主配置文件
etc/config.properties
与上述配置的差别：
coordinator=false
http-server.http.port=8080
discovery.uri=http://<coordinator-ip-or-host-name>:8080
将
Trino
安装和配置到一组节点上之后，你就可以使用启动器在每一个节点上启动
Trino
了。通常最好先启动
Trino
协调器，之后再启动工作节点。
$ bin/launcher start
与之前一样，可以使用
Trino CLI
来连接到
Trino
服务器。在分布式安装的情况下，需要
使用
--server
选项指定
Trino
协调器的地址。如果直接在
Trino
协调器所在的节点上运
行
Trino CLI
，因为该选项的默认值是
localhost:8080
，所以无须再指定。
$ trino --server <coordinator-ip-or-host-name>:8080
现在可以验证
Trino
集群是否正确运行。
nodes
系统表包含集群中当前所有的活动节点，
你可以使用
SQL
查询来查看它们：
trino> SELECT ＊ FROM system.runtime.nodes;
node_id | http_uri | node_version | coordinator | state
