同时运行Gremlin-Server和NEO4J Server [英] Have both Gremlin-Server AND NEO4J Server running at the same time

问题描述

当前看来，我们不能同时运行 Neo4J Server 和 Gremlin Server .有什么办法可以同时运行两者吗?

Current it seems we cannot run both Neo4J Server and Gremlin Server at the same time. Is there any way to have run both?

1. NEO4J正在运行，我尝试启动Gremlin Server，然后出现以下错误

java.lang.RuntimeException:GraphFactory无法实例化它 图的实现[类 org.apache.tinkerpop.gremlin.neo4j.structure.Neo4jGraph] .......................(被截短)

java.lang.RuntimeException: GraphFactory could not instantiate this Graph implementation [class org.apache.tinkerpop.gremlin.neo4j.structure.Neo4jGraph].......................(truncated)

1. Gremlin Server正在运行，我尝试启动NEO4J Server，然后出现以下错误

由以下原因引起:org.neo4j.kernel.StoreLockException:存储及其锁 文件已被另一个进程锁定: /home/galaxia/Documents/neo4j-gremlin/data/databases/graph.db/store_lock. 请确保没有其他进程正在使用该数据库，并且请确保 目录是可写的(甚至对于只读访问也是必需的)

Caused by: org.neo4j.kernel.StoreLockException: Store and its lock file has been locked by another process: /home/galaxia/Documents/neo4j-gremlin/data/databases/graph.db/store_lock. Please ensure no other process is using this database, and that the directory is writable (required even for read-only access)

推荐答案

您不能以这种方式(即嵌入式模式)一起运行它们，但如果可以，则可以一起运行它们:

You cannot run them together that way (i.e. embedded mode), but it should be possible to run them together, if you either:

1. 按照此处
2. 在Gremlin Server中配置Neo4j图以使用在此处找到的Bolt实现.
3. 在提供给Gremlin Server的Ne​​o4j属性文件中启用Bolt协议.

1. Configure the Neo4j graph in Gremlin Server to use HA mode as described here
2. Configure the Neo4j graph in Gremlin Server to use the Bolt implementation found here
3. Enable the Bolt protocol in the Neo4j properties file provided to Gremlin Server.

作为第三个选项的示例，给定Neo4j的默认Gremlin Server打包配置文件，您可以编辑conf/neo4j-empty.properties以包括:

As an example of the third option, given the default Gremlin Server packaged configuration files for Neo4j, you can edit conf/neo4j-empty.properties to include:

gremlin.graph=org.apache.tinkerpop.gremlin.neo4j.structure.Neo4jGraph
gremlin.neo4j.directory=/tmp/neo4j
gremlin.neo4j.conf.dbms.connector.0.type=BOLT
gremlin.neo4j.conf.dbms.connector.0.enabled=true
gremlin.neo4j.conf.dbms.connector.0.address=localhost:7687

，然后使用bin/gremlin-server.sh conf/gremlin-server-neo4j.yaml启动Gremlin Server，此时您可以针对同一图形实例使用标准的TinkerPop驱动程序以及标准的Bolt连接.

and then start Gremlin Server with bin/gremlin-server.sh conf/gremlin-server-neo4j.yaml at which point you can use standard TinkerPop drivers as well as standard Bolt connectivity against the same graph instance.
