Neo4j 索引错误导致数据库无法重启
Neo4j Index error causing database to not restart
我的VPS昨晚升级换了不同类型的SSD，但是我在关机和重启之前没有备份数据库。
在这个时间点之后，我一直无法重新启动数据库。尝试打开特定索引时错误日志开始显示失败，如下所示。
我试图通过重命名它存储的目录来绕过这个索引，但这没有效果。有没有其他方法可以删除有问题的索引，以便我可以在浏览器中重新启动数据库，然后稍后重新添加索引？

在这里找到答案：
https://community.neo4j.com/t/database-offline-and-will-not-restart/27914/5
作为此解决方案的一部分，索引问题似乎已消失。由于某种原因，neo4j 系统帐户不再有权写入日志文件或数据文件夹中的任何其他内容。这是解决使用：
sudo chown neo4j -R /var/lib/neo4j/data/

我有运行以下：
sudo neo4j-admin check-consistency --database=neo4j --check-indexes=true
并且可以看到索引显示正常（如果这是正在检查的内容？）

在这里找到答案： https://community.neo4j.com/t/database-offline-and-will-not-restart/27914/5
作为此解决方案的一部分，索引问题似乎已消失。由于某种原因，neo4j 系统帐户不再有权写入日志文件或数据文件夹中的任何其他内容。这是解决使用：
sudo chown neo4j -R /var/lib/neo4j/data/
