使用Neo4j 2.1.2数据库与Neo4j 2.1.3无法启动

我试图将我使用Neo4j 2.1.2的数据库复制到我从Neo4j 2.0.3升级到Neo4j 2.1.3的新机器上。似乎它已归结为Expected 'NeoStore v0.A.0' but file is version 'NeoStore v0.A.3'.，但我不知道如何解决这个问题。

这就是我的所作所为：

在我的旧服务器上：

  • 使用bin/neo4j stop
    • 关闭我的2.1.2服务器
  • 将graph.db目录复制到我的新服务器

在我的新服务器上：

  • 删除现有的graph.db目录
  • Ran apt-get install neo4j将新服务器从2.0.3升级到2.1.3
  • 服务器已成功启动但未发出警告
  • 删除了新创建的graph.db目录
  • 将我现有的graph.db目录复制到2.1.3
    • 的数据目录中
  • 让chown将文件的所有者更改为neo4j
  • 尝试使用sudo service neo4j-service start
    • 启动服务器
  • 还尝试设置allow_store_upgrade=true，但没有效果

以下是我得到的控制台输出：

Using additional JVM arguments:  -server -XX:+DisableExplicitGC -Dorg.neo4j.server.properties=conf/neo4j-server.properties -Djava.util.logging.config.file=conf/logging.properties -Dlog4j.configuration=file:conf/log4j.properties -XX:+UseConcMarkSweepGC -XX:+CMSClassUnloadingEnabled
Starting Neo4j Server...WARNING: not changing user
process [9107]... waiting for server to be ready... Failed to start within 120 seconds.

以下是messages.log中记录的错误：

这是console.log输出：

有关此功能的任何提示吗？我实际上从未成功地将数据库复制到运行新Neo4j版本的新服务器，并且实际上它已经工作，所以我显然使用了错误的进程。如果我让它创建一个新的空数据库，2.1.3服务器就可以正常运行了。

答案 0 :(得分：0)

尝试清除/ usr / share / neo4j / system / lib /中对2.0.3.jar的所有引用 - 确保只有2.1.3。

从您的日志看起来，您的/ neo4j / system / lib目录已合并在一起并包含不协调的jar文件。这些jar文件包含一些可能导致一些冲突问题的编译元数据。

与往常一样，在迁移之前备份您的数据存储文件。
