ubuntu - 如何将 neo4j 从 2.1.8 升级到 2.3.1

Question

我的 ubuntu ami 上安装了 neo4j 2.1.8。这个版本的 neo4j 的问题是它没有身份验证功能，并且像 DETACH 这样的一些查询不能在这个版本上运行。所以我决定升级我的 neo4j 但失败了。我遵循的步骤是:

停止正在运行的 neo4j

wget http://neo4j.com/artifact.php?name=neo4j-community-2.3.1-unix.tar.gz

tar -xf artifact.php\?name\=neo4j-community-2.3.1-unix.tar.gz

cd neo4j-community-2.3.1/

sudo vim conf/neo4j.properties 并设置 Neo4j 配置参数 allow_store_upgrade=true

sudo vim conf/neo4j-server.properties 并将数据库路径更改为旧数据库。

cd ../bin

./neo4j 开始

但不幸的是，我遇到了以下错误

如果在这个版本(2.1.8)中也可以进行身份​​验证，那么告诉过程，我不必更新我的数据库。

Answer 1

我想我记得必须从 2.1.x 升级到 2.2.x，然后再升级到 2.3.x
不存在从 2.1.x->2.3.x 的直接升级路径。

所以基本上，我设置了allow_store_upgrade=true在最新的 2.2.x 上，通过启动服务器升级数据库，关闭，将升级的数据库复制到 2.3.x 并重复该过程。

编辑 :手册确实表明有从 2.1.x -> 2.3.x ( http://neo4j.com/docs/stable/deployment-upgrading.html#explicit-upgrade ) 的直接升级路径，但这对我不起作用。
