Neo4j-从2.2.5升级到2.3.0后无法启动

这就是我得到的错误

数据库为空，没有graph.db目录

所有服务器属性文件与版本2.2.5中使用的服务器属性文件相同

以下是console.log的内容：

这里怎么了？

看起来更简单。我不得不更改参数org.neo4j.server.database.location=/home/ubuntu/data/neo4j data/graph.db，因为安装程序提供的默认位置是错误的。

您是否在neo4j.properties中激活了

allow\u store\u upgrade

配置？I data/graph.db/messages.log中是否有内容？graph.db文件夹不存在：ubuntu@ip-10-92-135-77:~/data/neo4j data$ls-lrt总计0参数allow_store_upgrade设置为true:#启用此选项可以从旧版本升级存储。allow\u store\u upgrade=true您是否已激活neo4j.properties中的

apt get

的方法来安装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地方，这样我就不必担心它安装在哪里了。由于Neo4j是自包含的，您可以在一个地方拥有所有内容（如果您需要，也可以不在一个地方，从

数据库.location

设置中找到）。是的，我总是使用apt get，因为我不知道如何使用curl和unzip下载。明白。这很简单。您可以运行

curlhttp://host/path >下载_path

然后下载

tar-xvzf neo4j-community-2.3.0.tar.gz

（请参阅）您是否使用类似于
