graph - DSE 图表 - 主机没有及时响应

Question

Gremlin 控制台似乎连接正确，但在任何查询后它都会回复“主机未及时响应”。

已经检查:
- 远程.yaml
- netstat --listen | grep 8182 (不返回任何内容)

小鬼线:

plugin activated: tinkerpop.tinkergraph
plugin activated: tinkerpop.server
plugin activated: tinkerpop.utilities
gremlin> :remote connect tinkerpop.server conf/remote.yaml
==>Configured localhost/127.0.0.1:8182
gremlin> :> 1+1
Host did not respond in a timely fashion - check the server status and submit again.

Answer 1

安装 DSE 时，Graph 服务会在本地网络接口(interface)(例如 10.x.x.x，而不是环回 127.0.0.1)中监听。

这意味着您需要编辑 Gremlin 控制台 YAML 并将其指向 10.x.x.x。
