janusgraph 自建server使用手记

环境

  1. java8环境

  2. hadoop安装启动

    version servers master
    cdh-hadoop-2.6.0 spark-slave10, spark-slave11, spark-slave12, spark-slave13, spark-slave14 spark-slave10
  3. hbase安装启动

    version servers master
    cdh-zookeeper spark-slave10, spark-slave12, spark-slave14
    hbase-1.2.0-cdh5.15.0 spark-slave10, spark-slave11, spark-slave12, spark-slave13, spark-slave14 spark-slave10
  4. es安装启动

    version servers master
    elasticsearch-5.6.0 spark-slave12, spark-slave13, spark-slave14 spark-slave14
  1. janusgraph安装

    • janusgraph-0.3.0-hadoop2
    • 10.179.90.75
    • vi conf/my-hbase-es.properties
    storage.backend=hbase
    storage.hostname=slave10.spark.com,slave12.spark.com,slave14.spark.com
    storage.port=2181
    index.search.backend=elasticsearch
    index.search.hostname=slave12.spark.com:9200,slave13.spark.com:9200,slave14.spark.com:9200
    storage.index.search.client-only=true
    storage.index.search.local-mode=false
    storage.index.search.sniff=false
    gremlin.graph=org.janusgraph.core.JanusGraphFactory
    storage.batch-loading=true
    force-index=true
    storage.hbase.table=myjanusgraph
    
  2. 环境变量

vi /etc/profile

export JANUSGRAPH_HOME='/home/janus/janusgraph-0.3.0-hadoop2'
export PATH=$PATH::$JANUSGRAPH_HOME/bin

source /etc/profile

本地初始化测试

gremlin.sh

gremlin> graph = JanusGraphFactory.open('conf/my-hbase-es.properties')
==>standardjanusgraph[hbase:[spark-slave10, spark-slave12, spark-slave14]]
gremlin> GraphOfTheGodsFactory.load(graph)
==>null
gremlin> g = graph.traversal()
==>graphtraversalsource[standardjanusgraph[hbase:[spark-slave10, spark-slave12, spark-slave14]], standard]
gremlin> saturn = g.V().has('name', 'saturn').next()
==>v[4112]
gremlin> g.V(saturn).valueMap()
==>[name:[saturn],age:[10000]]
gremlin> g.V(saturn).in('father').in('father').values('name')
==>hercules
