neo4j-shell无法连接到neo4j服务器

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。

运行neo4r:3.1.0 docker实例后，我在容器内运行bash：

$ docker exec -it neo4j /bin/bash

然后从那里尝试neo4j-shell像这样运行：

/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

我也试过其他主机，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：

$ 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

如您所见，这里没有1337开放！我已经查看了配置文件，并且指定端口的行已被注释掉，这意味着应将其设置为其默认值（1337）。

谁能帮助我使用neo4j-shell连接到neo4j？

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。

在3.1中，似乎默认情况下未启用外壳程序。

您将需要在启用外壳的情况下传递自己的配置文件：

取消评论

# 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。）

或使用新的cypher-shell：
