neo4j drwho数据集升级到3.0无法正常工作

标签： neo4j dataset upgrade

我正试图在我的Mac OSX中使用来自http://neo4j.com/developer/example-data/的“Jim Webber的Doctor Who数据集”和Neo4j 3.0.1社区。

我正在执行这些步骤（doc是here）：

  1. 将zip数据文件下载到导入目录中（为方便起见），并将其重命名为graph.db。
  2. 在dbms.allow_format_migration=true
    3. 中设置$NEO4J_HOME/conf/neo4j.conf
  3. 使用$NEO4J_HOME/bin/neo4j-admin import --mode=database --database=graph.db --from=$NEO4J_HOME/import/graph.db/
    4. 导入数据
  4. 启动neo4j服务器

    5. neo4j控制台无法启动，并显示以下错误消息：

    bin/neo4j console

    是否有人知道如何修复它？有没有人设法使用doc中的数据集？ 谢谢！

答案 0 :(得分：4)

Neo4j 3.0允许从任何干净关闭的Neo4j 2.x数据集直接升级。然而，您所指的DrWho数据集来自Neo4j 1.9（甚至更早）的旧时代。因此，您需要两步升级过程：

  1. 下载Neo4j 2.3.3（或任何新的2.x版本）
  2. 将drwho.zip解压缩到data/graph.db
  3. 在allow_store_upgrade=true
    4. 中设置conf/neo4j.properties
  4. 启动数据库并正常停止
  5. unpack neo4j 3.0.x
  6. 将data/graph.db从Neo4j 2.x复制到data/databases/graph.db
  7. 在dbms.allow_format_migration=true
    8. 中设置conf/neo4j.conf
  8. 启动Neo4j 3.0.x
