【问题描述】：
我最近在安装 Debian 7.8 时一直在玩 neo4j。太棒了！
今天我使用 neo4j-import 工具导入了大约 100000 个节点和 150000 个关系。我停止了 neo4j 服务并将导入的数据库复制到 /var/lib/neo4j/data/graph.db - 但现在 Neo4j 服务将无法启动
Starting Neo4j Server...WARNING: not changing user
process [4963]... waiting for server to be ready....... Failed to start within 120 seconds.
Neo4j Server may have failed to start, please check the logs.
这很奇怪，因为它不会等待 120 秒才能启动 - 最多 5 秒。生成的唯一日志是 /var/log/neo4j 中的 console.log
2015-07-01 00:10:24.363+0000 INFO [API] Setting startup timeout to: 120000ms based on 120000
2015-07-01 00:10:26.501+0000 INFO [API] Successfully shutdown Neo4j Server.
这不是很有用。当我删除数据库时，neo4j 能够启动。我将graph.db复制到我的Windows安装中，它运行良好，我可以搜索节点等。所以也许它与我的Debian上的配置有关？我在 /etc/neo4j/neo4j-server.properties 中添加了一行
org.neo4j.server.startup_timeout=0
但这并没有改变，几秒钟后服务启动仍然超时。有什么想法吗？
这里是 graph.db messages.log - 当我尝试启动服务时没有附加任何内容

neo4j 文档建议在这里问neo4j.com/docs/stable/community-support.html
-
Marcin，你能检查一下 graph.db/messages.log 吗？ neo4j-import 和 neo4j-server 是同一个版本吗？
-
嗨，迈克尔。我编辑了我的帖子以添加messages.log。没有任何错误。当我尝试启动服务器时，日志中没有任何内容。是的，我使用 neo4j 网站上的说明安装了带有 apt-get 的 neo4j，并在同一台服务器上导入了数据。
