如何用命令行开启数据节点

官方手册上看到的关于启动数据节点的方式是,进入到localhost:8848控制节点的web页面,通过页面启动.

https://github.com/dolphindb/...
上述链接中给出可以在控制节点通过
startDataNode(["DFS_NODE1", DFS_NODE2","DFS_NODE3","DFS_NODE4"])启动数据节点,对应的关闭函数是哪个?
但是我想./dolphin进入命令行界面启动数据节点,命令是怎样的,就像类似启动控制节点和代理节点一样?

回答

在web上启动数据数据节点后,可以到shell中运行

ps -ef |grep dolphindb

例如我服务器上显示如下:

其中下面的命令就是启动了2个数据节点:
