Question

我是本科生，我正在将Neo4j用于我的高级论文项目。我在Mac上运行它，几天前我的笔记本电脑被锁定了，我不得不将它关闭不当。我不确定这是否会导致我当前的问题，但从那以后我一直无法启动Neo4j。我在控制台中运行./neo4j start，发生以下错误：

./neo4j start console

昨晚我删除了除graph.db以外的Neo4j文件夹并下载了最新版本，因此我从2.0.0升级到2.0.1。但是，启动错误仍然存在。

如果有人可以提供帮助，我会非常感激。时间在我的截止日期前滴答作响！谢谢。

更新

这是messages.log文本，它很长。

Answer 1

您列出的日志文件根本没有提到2.0.1，只有2.0.0。

我会再次尝试下载Neo4j 2.0.0，看看它是否成功。如果是，请尝试干净地关闭，然后再次启动升级过程。您之前执行的不洁关闭可能会阻止Neo4j正常升级。

更实际的是，我还建议您使用2.0.0进入工作状态，假设您不需要2.0.1的功能。

Answer 2

你能上传graph.db / messages.log - 这可能有某种错误信息可以解释发生了什么。

Answer 3

尝试使用旧版本的Noe4j服务器打开数据库时，我遇到了一个非常类似的问题。使用相同的版本只是做到了，但找出问题不是最明显的。

查看graph.db / messages.log正如Mark建议帮助的那样，来自console.log的消息对我来说信息量较少，只是说“检测到错误地关闭了数据库，执行恢复......”。

Neo4j 2.0.1无法启动
