Question

我在Windows机器上创建了一个neo4j数据库。我已将数据库目录的内容传输到我的linux机器。这是因为我的社区版本不支持备份功能。

mtt@mttPC:/var/lib/neo4j/data/log$ sudo service neo4j-service start
WARNING: Max 1024 open files allowed, minimum of 40 000 recommended. See the Neo4j manual.

数据库目录中的文件messages.log什么也没说。

有什么想法吗？ Windows和Linux neo4j是否兼容？谢谢。

修改

我已经在我的ubuntu机器上全新安装了neo4j。

现在我终于得到了一些日志：

2014-05-16 20:01:10.958+0000 ERROR [o.n.k.EmbeddedGraphDatabase]: Startup failed: Component 'org.neo4j.kernel.impl.transaction.XaDataSourceManager@25984c63' was successfully initialized, but failed to start. Please see attached cause exception.: Component 'org.neo4j.kernel.impl.nioneo.xa.NeoStoreXaDataSource@3d34dcb' was successfully initialized, but failed to start. Please see attached cause exception.: 'neostore' has a store version number that we cannot upgrade from. Expected 'NeoStore v0.A.0' but file is version 'NeoStore v0.A.2'.
2014-05-16 20:01:10.958+0000 INFO  [o.n.k.EmbeddedGraphDatabase]: Shutdown started

我应该与this有关，但我不确定如何继续。这个问题是否与我复制数据库的时候有关，我刚从neo4j窗口停止了我的windows机器上的neo4j？

Answer 1

Neo4j数据库没有理由不能在操作系统之间转移。你能否提供data/log/console.log的输出？首先想到的是你可能有许可问题。应该为Neo4j进程运行的用户读/写文件。

从windows导入neo4j数据库到ubuntu
