Neo4j - 从2.2.5升级到2.3.0后无法启动

数据库为空，没有graph.db目录。

所有的服务器属性文件与用于版本2.2.5的文件相同。

这里的console.log的内容：

这里有什么问题？

你是否在neo4j.properties中激活了'allow_store_upgrade'配置？我有一些东西在data/graph.db/messages.log？ – logisima

文件夹graph.db不存在： Ubuntu的@ IP-10-92-135-77：〜/数据/ Neo4j的数据$ LS -lrt 共0 该参数allow_store_upgrade设置为true：＃启用此以便能够从旧版本升级商店。 allow_store_upgrade = true – LDB

看起来这是马赫简单的东西。由于安装程序提供的默认位置错误，我不得不更改参数org.neo4j.server.database.location =/home/ubuntu/data/neo4j-data/graph.db。

您是否使用'apt-get'来安装Neo4j？我经常使用curl直接从neo4j.com下载Neo4j，并将其解压缩到我想要的位置，这样我就不必担心它的安装位置。由于Neo4j是自包含的，你可以在一个地方拥有所有东西（或者不是，如果这就是你想要的，就像你从'database.location'设置中找到的那样） –

是的，我总是使用apt-get，因为我不知道如何用curl和解压缩来下载。 – LDB

了解。这非常简单。你可以运行'curl http：// host/path> download_path'，然后运行'tar -xvzf neo4j-community-2.3.0.tar.gz'（参见http://askubuntu.com/questions/25347/what-command -do -i-need-to-unzip-extract-a-tar-gz-file） –
