Amazon EC2上的Neo4j-无法从远程计算机访问 [英] Neo4j on Amazon EC2 - Not accessible from remote machines
本文介绍了Amazon EC2上的Neo4j-无法从远程计算机访问的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！
问题描述
我目前正在尝试使用RHEL在EC2实例上正确安装neo4j.目前，我无法从浏览器访问端口7474上的服务器来查看neo4j Webadmin或浏览器.截至目前，我可以成功访问localhost:7474，这使我相信这是远程连接的某种程度的访问问题.
I am currently attempting to get neo4j installed properly on an EC2 instance with RHEL. Currently I can not hit the server on port 7474 from a browser to see the neo4j webadmin or browser. As of right now I can successfully access localhost:7474 which leads me to believe it is some level of access issue with remote connections.
到目前为止我所做的:
- 在EC2实例上安装了Oracle Java 1.7
- 已安装neo4j-community-2.0.1
- 将org.neo4j.server.webserver.address = 0.0.0.0添加到neo4j-server.properties
- 在EC2 UI中为端口7474添加了自定义TCP规则，允许0.0.0.0/0
- 为iptables添加了7474
- 重新启动实例
- 运行neo4j start
在查看netstat时，我看到该进程正在侦听端口7474，因此我不确定还有什么会阻止外部流量访问端口7474上服务器的公共EC2 DNS.
Looking at netstat I see the process listening on port 7474, so I am unsure what else would be preventing external traffic from hitting the public EC2 DNS for the server on port 7474.

推荐答案
您的EC2实例是否是VPC内安全组的一部分? 作为一种故障排除技术，您可以尝试将nginx用作可以执行80 <->> 7474的代理，并查看它是否为您提供一种至少可以在解决问题时访问它的方法...
Is your EC2 instance part of a security group within a VPC? As a troubleshooting technique - you can try to put nginx as a proxy that does 80<->7474, and see if that gives you a way to at least access it while you work through the issues...
