Question

我的Neo4j数据库服务器托管在AWS。

我在Mac上使用此命令：

$ ./bin/neo4j-shell -host xx.xxx.xxx.xxx -port 1337 -name shell

在AWS Neo4j数据库服务器中启用了端口1337。

我在neo4j.properties文件中取消注释这些行：

remote_shell_enabled=true
remote_shell_host=127.0.0.1
remote_shell_port=1337

我收到错误：拒绝连接

有详细信息：

不知道如何修复它。

Answer 1

我认为您必须在服务器上打开相当多的端口，除了1337和1099之外还有RMI端口的端口范围。

e.g。 What port is used by Java RMI connection?

您也可以通过http使用neo4j（例如在浏览器中使用/ webadmin）或通过此脚本：https://gist.github.com/jexp/a9bf4cd3a16eb6c5997b

Answer 2

此键remote_shell_host=127.0.0.1使您可以通过环回连接。您必须指定您将通过哪个网络适配器接收连接。您还可以为任何网络接口指定0.0.0.0。
