Question

我的Neo4j数据库没有响应，所以我不得不杀死这个过程，之后就不再启动了。有人可以帮我解决一下吗？这是错误日志：

Answer 1

Caused by: org.neo4j.kernel.StoreLockException: Store and its lock file has been locked by another process: data/graph.db/store_lock. Please ensure no other process is using this database, and that the directory is writable (required even for read-only access)

看起来你仍然在后台运行一些neo4j进程。看看你能否找到它然后杀死它。

Answer 2

今天早上我遇到了同样的错误消息。这对我有用。我创建了一个新的数据库文件夹，将启动屏幕指向新位置 - 启动成功。然后我关闭这个新实例并重新指向一个现有的（失败的）db位置，然后按正常方式启动。我希望它有所帮助。

Answer 3

我删除了现有的图并创建了一个新图。这次，我确保选择了与最新插件（APOC等）库版本相匹配的Graph（在我的情况下为3.5.0）正确版本，并且我的数据库已成功启动。

Neo4j不再启动了
