安裝

解壓?janusgraph-0.3.2-hadoop2.zip?文件

janusgraph單機版安裝

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

1.安裝jdk

2.安裝janusgraph

unzip janusgraph-0.3.2-hadoop2.zip

3.配置啟動配置文件conf/gremlin-server/gremlin-server.yaml

4.配置啟動配置文件conf/gremlin-server/janusgraph-hbase-solr.properties

# 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?配置文件說明：

storage.backend=hbase //使用HBase作為存儲后端 storage.hostname=zookeeper-host1,zookeeper-host2,zookeeper-host3 //HBase的Zookeeper storage.hbase.table=janusgraph//HBase存儲JanusGraph元數據的表名 storage.hbase.ext.zookeeper.znode.parent=/hbase //HBase使用的Znode storage.hbase.ext.hbase.zookeeper.property.clientPort=2181 //端口HBase的查詢是基于Rowkey，所以在條件查詢這塊是弱項，一旦Rowkey確定如果有新的查詢就比較難。所以為了解決這個問題，JanusGraph引入了索引后端，下面我們介紹下如何配置Solr作為JanusGraph的索引后端。配置文件conf/janusgraph-hbase-solr.properties配置參數如下：index.search.backend=solr //使用solr作為索引后端 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的元數據表名
