http://www.ibm.com/developerworks/cn/java/j-lo-neo4j/
Step1.下载neo4j商业版并解压,复制为neo4j01,neo4j02,neo4j03
Step2.修改neo4j.properties 文件和neo4j-server.properties文件,
按照neo4j manual上面的要求修改即可.
The following settings should be configured for each Neo4j installation. Neo4j instance #1—~/neo4j-01 conf/neo4j.properties: Unique server id for this Neo4j instance can not be negative id and must be unique ha.server_id = 1 IP and port for this instance to bind to for communicating data with the other neo4j instances in the cluster. ha.server = 127.0.0.1:6363 online_backup_server = 127.0.0.1:6366 IP and port for this instance to bind to for communicating cluster information with the other neo4j instances in the cluster. ha.cluster_server = 127.0.0.1:5001 List of other known instances in this cluster ha.initial_hosts = 127.0.0.1:5001,127.0.0.1:5002,127.0.0.1:5003 conf/neo4j-server.properties database location org.neo4j.server.database.location=data/graph.db http port (for all data, administrative, and UI access) org.neo4j.server.webserver.port=7474 High Availability 424 https port (for all data, administrative, and UI access) org.neo4j.server.webserver.https.port=7484 HA - High Availability SINGLE - Single mode, default. org.neo4j.server.database.mode=HA Neo4j instance #2—~/neo4j-02 conf/neo4j.properties: Unique server id for this Neo4j instance can not be negative id and must be unique ha.server_id = 2 IP and port for this instance to bind to for communicating data with the other neo4j instances in the cluster. ha.server = 127.0.0.1:6364 online_backup_server = 127.0.0.1:6367 IP and port for this instance to bind to for communicating cluster information with the other neo4j instances in the cluster. ha.cluster_server = 127.0.0.1:5002 List of other known instances in this cluster ha.initial_hosts = 127.0.0.1:5001,127.0.0.1:5002,127.0.0.1:5003 conf/neo4j-server.properties database location org.neo4j.server.database.location=data/graph.db http port (for all data, administrative, and UI access) org.neo4j.server.webserver.port=7475 https port (for all data, administrative, and UI access) org.neo4j.server.webserver.https.port=7485 HA - High Availability SINGLE - Single mode, default. org.neo4j.server.database.mode=HA Neo4j instance #3—~/neo4j-03 conf/neo4j.properties: Unique server id for this Neo4j instance can not be negative id and must be unique ha.server_id = 3 IP and port for this instance to bind to for communicating data with the other neo4j instances in the cluster. ha.server = 127.0.0.1:6365 online_backup_server = 127.0.0.1:6368 IP and port for this instance to bind to for communicating cluster information with the other neo4j instances in the cluster. ha.cluster_server = 127.0.0.1:5003 List of other known instances in this cluster ha.initial_hosts = 127.0.0.1:5001,127.0.0.1:5002,127.0.0.1:5003 conf/neo4j-server.properties database location High Availability 425 org.neo4j.server.database.location=data/graph.db http port (for all data, administrative, and UI access) org.neo4j.server.webserver.port=7476 https port (for all data, administrative, and UI access) org.neo4j.server.webserver.https.port=7486 HA - High Availability SINGLE - Single mode, default. org.neo4j.server.database.mode=HA
