neo4j-shell无法连接到neo4j服务器 [英] neo4j-shell can not connect to neo4j Server

问题描述

我正在使用neo4j(v3.1.0)的docker版本，并且在使用neo4j-shell连接到neo4j服务器时遇到困难.

I'm using docker version of neo4j (v3.1.0) and I'm having difficulties connecting to neo4j server using neo4j-shell.

在运行neo4r:3.1.0 docker 的实例后，我在容器:

After running an instance of neo4r:3.1.0 docker, I run a bash inside the container:

$ docker exec -it neo4j /bin/bash

然后从那里尝试像这样运行neo4j-shell:

And from there I try to run the neo4j-shell like this:

/var/lib/neo4j/bin/neo4j-shell

但是它出错了:

$ /var/lib/neo4j/bin/neo4j-shell 
ERROR (-v for expanded information):
    Connection refused

 -host      Domain name or IP of host to connect to (default: localhost)
 -port      Port of host to connect to (default: 1337)
 -name      RMI name, i.e. rmi://<host>:<port>/<name> (default: shell)
 -pid       Process ID to connect to
 -c         Command line to execute. After executing it the shell exits
 -file      File containing commands to execute, or '-' to read from stdin. After executing it the shell exits
 -readonly  Connect in readonly mode (only for connecting with -path)
 -path      Points to a neo4j db path so that a local server can be started there
 -config    Points to a config file when starting a local server

Example arguments for remote:
    -port 1337
    -host 192.168.1.234 -port 1337 -name shell
    -host localhost -readonly
    ...or no arguments for default values
Example arguments for local:
    -path /path/to/db
    -path /path/to/db -config /path/to/neo4j.config
    -path /path/to/db -readonly

我还尝试了其他主机，例如:localhost，127.0.0.1和172.17.0.6(容器IP).由于它不起作用，我尝试列出容器上的打开端口:

I also tried other hosts like: localhost, 127.0.0.1 and 172.17.0.6 (the container IP). Since it didn't work I tried to list open ports on my container:

$ netstat -l
Active Internet connections (only servers)
Proto Recv-Q Send-Q Local Address           Foreign Address         State       
tcp        0      0 :::7687                 :::*                    LISTEN      
tcp        0      0 :::7473                 :::*                    LISTEN      
tcp        0      0 :::7474                 :::*                    LISTEN      
Active UNIX domain sockets (only servers)
Proto RefCnt Flags       Type       State         I-Node Path

您可以看到没有打开1337！我查看了配置文件，并注释掉了用于指定端口的行，这意味着应将其设置为默认值(1337).

As you can see there's no 1337 open! I've looked into the config file and the line for specifying port is commented out which means it should be set to its default value (1337).

有人可以使用neo4j-shell帮助我连接到neo4j吗?

Can anyone help me connect to neo4j using neo4j-shell?

顺便说一句，neo4j服务器已启动并正在运行，我可以通过端口:7474使用其Web访问.

BTW, the neo4j server is up and running and I can use its web access through port :7474.

推荐答案

在3.1中，似乎默认情况下未启用外壳程序.

In 3.1 it seems the shell is not enabled by default.

您将需要在启用外壳的情况下传递自己的配置文件:

You will need to pass your own configuration file with the shell enabled :

取消注释

# Enable a remote shell server which Neo4j Shell clients can log in to.
dbms.shell.enabled=true

(我发现在docker中更改一个值的工作人员数量很大，但是是的.)

(I find the amount of worker for changing one value in docker quite heavy but yeah..)

或使用新的cypher-shell:

Or use the new cypher-shell :
