Question

我在服务器上安装了Neo4j 2.3.2，其防火墙的端口为1337,7474,7473（使用ncat验证）。我可以远程访问基于Web的控制台，可以在本地访问shell，但我无法远程访问shell。也就是说，在运行path/to/neo4j-shell -v -host destination.example.org时，我得到了

在/var/lib/neo4j/conf/neo4j.properties，我有

# Enable shell server so that remote clients can connect via Neo4j shell.
remote_shell_enabled=true
# The network interface IP the shell will listen on (use 0.0.0.0 for all interfaces).
remote_shell_host=0.0.0.0
# The port the shell will listen on, default is 1337.
remote_shell_port=1337

除了提到的三个外，我还需要打开其他端口吗？是否有任何与我错过的shell有关的进一步配置？

neo4j-shell基于Java RMI。有几个资源描述了如何为RMI进行防火墙。事实上，由于RMI正在进行动态端口分配，因此它非常复杂。

通常我通过ssh连接在本地运行neo4j-shell，这也为您提供身份验证和加密 - 您只需要打开SSH端口。

无法使用neo4j-shell连接到远程Neo4j服务器
