通过Java代码生成db后Neo4j 2.2.1服务器无法启动 [英] Neo4j 2.2.1 server does not start after db is generated via java code

问题描述

从一个新的graph.db文件夹开始.我正在使用嵌入式图db，java和cypher查询来创建节点.似乎成功创建了节点.已经调试并检查了结果对象.

Started with a new graph.db folder. Am using embedded graph db, java and cypher query to create nodes. It seems to create the nodes successfully. Have debugged and checked the result object.

我现在想启动neo4j服务器来检查浏览器中的节点.但是，它给出了消息:

I want to now start the neo4j server to check the nodes in the browser. However, it gives the message:

bash-4.2 $ ./neo4j-community-2.2.1/bin/neo4j start

bash-4.2$ ./neo4j-community-2.2.1/bin/neo4j start

警告:最多1024 允许打开文件，建议至少40 000.见Neo4j 手动的.正在启动Neo4j Server ...

WARNING: Max 1024 open files allowed, minimum of 40 000 recommended. See the Neo4j manual. Starting Neo4j Server...

警告:不更改用户流程 [2868] ...正在等待服务器准备就绪……无法在内部启动 120秒Neo4j Server可能无法启动，请检查 日志.

WARNING: not changing user process [2868]... waiting for server to be ready...... Failed to start within 120 seconds. Neo4j Server may have failed to start, please check the logs.

我检查了console.log和message.log.但是没有错误.我不知道要在日志文件中读取哪些内容以进行诊断.请指教.

I checked the console.log and message.log. But there is not error. I don't know what to read in the log files to put up here for diagnosis. Please advice.

Console.log:

我还应该在哪里寻找错误?如何启动neo4j服务器?

Where else should I look for errors? How can I get the neo4j server up?

已检查messages.log.下面的文字.所以看起来可以通过以下代码关闭:

Checked messages.log. Text below. So looks like it is shutting down ok via the code:
