Question

我正在使用AWS服务器ec2 ubuntu实例上的neo4j。

一切都很好，但是当我创建ec2实例的图像时，实例必须重新启动，因为我无法运行我的neo4j数据库服务器。

我在console.log文件中看到的唯一内容如下：

2015-05-01 16:50:18.135+0000 INFO  [API] Successfully shutdown Neo4j Server.
2015-05-01 16:50:18.304+0000 INFO  [API] Successfully stopped database

2015-05-01 17:43:13.906+0000 INFO  [API] Setting startup timeout to: 120000ms based on -1

服务器总是说它无法启动，我不知道该做什么或问题出在哪里..

有什么想法吗？

Answer 1

因为服务器默认开始于（1200000ms）2分钟，所以它将在时间限制内失败 1.检查/path/data/graph.db(或您的数据库）/message.log 2.set /path/conf/neo4j-server.properties并在其中添加第3步

3.org.neo4j.server.startup_timeout = 0

该集合用于禁用启动限制行为。

Answer 2

您应为您的实例分配 IAM角色。当neo4j加载时，它执行以下脚本：

/etc/neo4j/pre-neo4j.sh

正在呼叫：

aws ec2 describe-tags ...

Neo4j未能在ubuntu上启动
