Amazon EC2上的Neo4j-无法从远程计算机访问

Question

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。 到目前为止，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。

到目前为止，我所做的是：

1. 在EC2实例上安装了Oracle Java 1.7
2. 已安装neo4j-community-2.0.1
3. 在neo4j-server.properties中添加了org.neo4j.server.webserver.address = 0.0.0.0
4. 在EC2 UI中为端口7474添加了自定义TCP规则，允许0.0.0.0/0
5. 向iptables添加了7474
6. 重新启动实例
7. 运行neo4j start

查看netstat时，我看到该进程在端口7474上侦听，因此我不确定还有什么会阻止外部流量访问端口7474上的服务器的公共EC2 DNS。

Answer 1

您的EC2实例是否属于VPC内的安全组？ 作为一种故障排除技术，您可以尝试将nginx用作执行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对其进行访问的方法...

Answer 2

我遇到了完全相同的问题，原来是由EC2中的安全组管理方式导致的。 基本上，我必须去“网络接口”，选择“操作”，然后选择“更改安全组”，然后添加我新创建的安全组。
