无法在Windows上启动Neo4j，没有错误消息 [英] Unable to start Neo4j on Windows, no error messages

问题描述

我在Windows 7上使用以下内容:

I'm using the following on Windows 7:

• neo4j-community-1.9.2
• Java 7 Update 25

我禁用了Windows防火墙.

I have Windows Firewall disabled.

以管理员身份和通常身份启动Neo4j.bat时，出现以下消息:

When I start Neo4j.bat, both as Administrator and normally, I get the following message:

c:\Tools\neo4j\bin>Neo4j.bat 
28/07/13 9:34:27 PM org.neo4j.server.AbstractNeoServer INFO: Setting startup tim 
eout to: 120000ms based on -1

空白的Java控制台窗口弹出，没有消息，然后一分钟左右消失.

A blank Java console window pops up, no messages, then the window disappears after a minute or so.

当我转到http://localhost:7474/时，我只是收到未找到服务器的错误.

When I go to http://localhost:7474/, I just get a server not found error.

如果我尝试将其安装为服务，则该服务将无法启动.

If I try to install it as a service, the service wouldn't start.

有什么想法可以启动Neo4j吗?我在这里看到Neo4j 1.9确实支持Java 7:

Any ideas what I need to do to start Neo4j? I see here that Neo4j 1.9 does support Java 7:

base.bat正确指向windows-service-wrapper-5.jar，所以不是某些人过去遇到的windows-service-wrapper-*.jar问题.如果输出错误消息，将很有帮助.

base.bat correctly points to windows-service-wrapper-5.jar, so not the windows-service-wrapper-*.jar problem that some people have had in the past. It would be helpful if it outputted an error message.

我刚刚在neo4j 2.0里程碑上进行了尝试，但没有任何区别. Java窗口不显示任何消息，弹出http://localhost:7474/找不到服务器错误，然后一两分钟后关闭Java窗口.

I just tried it with neo4j 2.0 milestone, and it didn't make any difference. The Java window pops up with no messages, http://localhost:7474/ gets a server not found error, then the Java window closes after a minute or two.

我添加了JAVA_HOME和JRE_HOME系统变量，没有区别.如果Neo4j无论如何都找不到Java，我想我会得到一个错误.

I added JAVA_HOME and JRE_HOME system variables, made no difference. I think I would get an error if Neo4j was not able to locate Java anyway.

推荐答案

我已修复它.

在Neo4j的Google网上论坛的帮助下，我查看了data/logs/*.log和data/graph.db/messages.log中的日志，发现以下异常:

With help from Neo4j's Google Group, I looked at the logs in data/logs/*.log and data/graph.db/messages.log, and found the following exception:

Caused by: java.rmi.server.ExportException: Port already in use: 1337; nested exception is:
    java.net.BindException: Address already in use: JVM_Bind

一旦我禁用了使用该端口的其他服务，http://localhost:7474处的Neo4j的Web管理员就会起作用.然后我发现Neo4j的远程Shell使用了端口1337，我通过在neo4j.properties中添加enable_remote_shell = false来禁用它，然后我就可以同时运行Neo4j和其他服务.

Once I disabled my other service that uses that port, Neo4j's web admin at http://localhost:7474 worked. I then found out port 1337 is used by Neo4j's remote shell, I disabled it by adding enable_remote_shell = false to neo4j.properties, then I was able to have both Neo4j and my other service running.
