Neo4j服务器无法在120秒内启动

Question

我正在尝试在AWS上运行Neo4j服务器,但它发出以下错误:

* Restarting Neo4j Graph Database neo4j
WARNING: Max 1024 open files allowed, minimum of 40 000 recommended. See the Neo4j manual.
Using additional JVM arguments:  -server -XX:+DisableExplicitGC -Dorg.neo4j.server.properties=conf/neo4j-server.properties -Djava.util.logging.config.file=conf/logging.properties -Dlog4j.configuration=file:conf/log4j.properties -XX:+UseConcMarkSweepGC -XX:+CMSClassUnloadingEnabled
Starting Neo4j Server...WARNING: not changing user
process [26079]... waiting for server to be ready.......... Failed to start within 120 seconds.
Neo4j Server may have failed to start, please check the logs.

搜索Google我发现信息建议将打开文件的最大数量增加到40000; 我试过了,但不幸的是结果是一样的.

眼镜:

• 操作系统版本:Ubuntu 14.04 LTS
• Neo4j:2.0.3稳定版

此外,我在停止服务器后通过批量导入程序从两个CSV文件进行批量导入,但是当我在导入后重新启动服务器时,它不会启动并产生上述错误.

要增加允许的打开文件数,请查看http://docs.neo4j.org/chunked/stable/linux-performance-guide.html#_setting_the_number_of_open_files.

如果它还没有启动检查data/log/console.log或使用neo4j start-no-wait.
