安装

解压 janusgraph-0.3.2-hadoop2.zip 文件

janusgraph单机版安装

注：本次安装janusgraph基于es和hbse，所以先安装es和hbase

1.安装jdk

2.安装janusgraph

unzip janusgraph-0.3.2-hadoop2.zip

3.配置启动配置文件conf/gremlin-server/gremlin-server.yaml

# functionality. This setting is optional.  JanusGraph can use multiple
# heterogeneous index backends.  Hence, this option can appear more than
# once, so long as the user-defined name between "index" and "backend" is
# unique among appearances.Similar to the storage backend, this should be
# set to one of JanusGraph's built-in shorthand names for its standard
# index backends (shorthands: lucene, elasticsearch, es, solr) or to the
# full package and classname of a custom/third-party IndexProvider
# implementation.
#
# Default:    elasticsearch
# Data Type:  String
# Mutability: GLOBAL_OFFLINE
#
# Settings with mutability GLOBAL_OFFLINE are centrally managed in
# JanusGraph's storage backend.  After starting the database for the first
# time, this file's copy of this setting is ignored.  Use JanusGraph's
# Management System to read or modify this value after bootstrapping.
index.search.backend=solr
gremlin.graph=org.janusgraph.core.JanusGraphFactory
# The operation mode for Solr which is either via HTTP (`http`) or using
# SolrCloud (`cloud`)
#
# Default:    cloud
# Data Type:  String
# Mutability: GLOBAL_OFFLINE
#
# Settings with mutability GLOBAL_OFFLINE are centrally managed in
# JanusGraph's storage backend.  After starting the database for the first
# time, this file's copy of this setting is ignored.  Use JanusGraph's
# Management System to read or modify this value after bootstrapping.
index.search.solr.mode=http# List of URLs to use to connect to Solr Servers (LBHttpSolrClient is
# used), don't add core or collection name to the URL.
#
# Default:    http://localhost:8983/solr
# Data Type:  class java.lang.String[]
# Mutability: MASKABLE
index.search.solr.http-urls=http://192.168.2.116:8983/solr
index.search.solr.mode=cloud
index.search.solr.zookeeper-ur=192.168.2.116:2181/solr
index.search.solr.configset=janusgraph

janusgraph-hbase-solr.properties 配置文件说明：

storage.backend=hbase //使用HBase作为存储后端
storage.hostname=zookeeper-host1,zookeeper-host2,zookeeper-host3 //HBase的Zookeeper
storage.hbase.table=janusgraph//HBase存储JanusGraph元数据的表名
storage.hbase.ext.zookeeper.znode.parent=/hbase //HBase使用的Znode
storage.hbase.ext.hbase.zookeeper.property.clientPort=2181 //端口HBase的查询是基于Rowkey，所以在条件查询这块是弱项，一旦Rowkey确定如果有新的查询就比较难。所以为了解决这个问题，JanusGraph引入了索引后端，下面我们介绍下如何配置Solr作为JanusGraph的索引后端。配置文件conf/janusgraph-hbase-solr.properties配置参数如下：index.search.backend=solr //使用solr作为索引后端
index.search.solr.mode=cloud //solr使用集群模式
index.search.solr.zookeeper-url=zookeeper-host1:2181/solr,zookeeper-
host2:2181/solr,zookeeper-host3:2181/solr //HBase使用的Zookeeper
index.search.solr.configset=janusgraph //Solr使用HBase的元数据表名
