neo4j-shell“连接拒绝”错误

Question

我在Mac（ML）上运行2.0.0 M06

Neo4j正在运行，Web控制台正常运行。但是当我尝试通过Neo4j-shell连接时，它失败了。星期三一切都很好，但在尝试Postgres安装（MusicBrainz Neo4j项目的一部分）之后出现了这个问题：

Example arguments for remote:

Answer 1

在neo4j.conf中，您必须取消注释与使用neo4j-shell有关的行

# Enable a remote shell server which Neo4j Shell clients can log in to.
dbms.shell.enabled=true
# The network interface IP the shell will listen on (use 0.0.0.0 for all interfaces).
dbms.shell.host=127.0.0.1
# The port the shell will listen on, default is 1337.
dbms.shell.port=1337

这为我解决了这个问题

Answer 2

重点是服务器绑定到localhost（127.0.0.1）并且shell尝试连接到172.16.31.31，这是另一个网络接口，而不是环回。这就是你到达connection refused的原因。

Answer 3

打开命令提示符：

C：\ Users \ nsh004 \ Documents \ Neo4j＆gt; Neo4jShell -path C：\ Users \ nshinde004 \ Documen ts \ Neo4j \ Demo1 -file load.cql

这对我有用。我们必须提供数据库的路径。一旦我提供它工作!! :-)

Answer 4

我遇到了同样的问题。

我的配置是：

• 窗口-7- X32
• 的Neo4j-2.1.4
• neo4j作为服务启动

Neo4jShell.bat工作文件util我关闭笔记本（睡眠模式）。 在恢复之后，看起来像neo4j进程以某种方式＆＃34;松散＆＃34;要听的端口。 取决于情况1337端口可以由不同的进程使用

[nvstreamsvc.exe]   TCP 127.0.0.1:1337 notebook：0 LISTENING

[Dropbox.exe]   TCP 127.0.0.1:1337 notebook：0 LISTENING

在我的情况下，解决方案是通过Windows任务管理器重新启动Neo4j-Server服务。

我希望这会有所帮助。

Answer 5

如果您使用以下命令拥有数据库文件夹，则可以在没有主机的情况下导出neo4j数据库：

neo4j-shell -path /var/lib/neo4j/data/databases/graph.db -c dump > export_data.cypher -v

它将创建名为＆＃34; export_data.cypher＆＃34;的文件。在您当前的目录中。

希望它有所帮助。
