如何在titan/hbase的远程gremlin服务器上运行gremlin脚本？,gremlin,titan,tinkerpop,gremlin-server,Gremlin,Titan,Tinkerpop,Gremlin Server,我正在使用titan/hbase存储数据，titan和hbase驻留在远程服务器机器中。我用bin/titan.sh start启动了Gremlin服务器。之后，我在服务器计算机上运行了以下命令，运行良好： bin/gremlin.sh \,,,/ (o o) -----oOOo-(3)-oOOo----- plugin activated: aurelius.titan plugin activated: tinkerpop.server plugin

现在，为了检查远程连接，我刚从客户机运行了

gremlin.sh

，然后

gremlin> :remote connect tinkerpop.server conf/remote.yaml 
g=TitanFactory.open("conf/titan-hbase.properties")

我得到以下信息：

而remote.yaml是：

hosts: [192.168.1.65]
port: 8182
serializer: { className: org.apache.tinkerpop.gremlin.driver.ser.GryoMessageSerializerV1d0, config: { serializeResultToString: true }}

这里出了什么问题？如何实现这一点？

您需要做的是使用Titan HBase属性配置Gremlin服务器。在这种情况下，您根本不应该使用

titan.sh

，因为它会自动启动Cassandra和Elasticsearch节点，所以请确保在继续之前使用

bin/titan.sh stop

关闭该节点

将您的

titan hbase.properties

放在

conf/gremlin server/

下。您在上面发布的内容看起来不错，只是最后一个属性名应该是

storage.hbase.table

使用Titan HBase配置更新

conf/gremlin server/

下的

gremlin server.yaml

（默认配置使用Cassandra+Elasticsearch）。此外，请记住，如果要从其他计算机连接到Gremlin服务器，则需要将主机更新为服务器的IP地址

192.168.1.65

图：{graph:conf/gremlin server/titan-hbase.properties}

使用

bin/Gremlin Server.sh

启动Gremlin服务器。在启动时查看日志中的错误。如果成功，您将看到一条信息消息，说明

graph

和

已配置并绑定

在

scripts/empty sample.groovy

脚本中定义，该脚本通过

conf/gremlin server.yaml

加载

8456[main]INFO org.apache.tinkerpop.gremlin.server.GremlinServer-已通过[conf/gremlin server/titan hbase.properties]成功配置图形[Graph]。
9349[main]INFO org.apache.tinkerpop.gremlin.server.util.ServerGremlinExecutor-GraphTraversalSource[standardtitangraph[hbase:[127.0.0.1]]，standard]

启动Gremlin控制台，并使用

conf/remote.yaml

创建到Gremlin服务器的远程连接。由于

graph

和

已经通过服务器配置绑定，因此不需要在控制台中初始化它们。确保在查询开始时使用

：>

将命令发送到远程服务器

下面是一个小精灵控制台会话示例：

gremlin> :remote connect tinkerpop.server conf/remote.yaml
==>Connected - localhost/127.0.0.1:8182
gremlin> :> g.V().count()
==>12

请参阅，以从Gremlin控制台连接到Gremlin服务器。
