neo4j-shell 无法连接到 neo4j 服务器

Question

我正在使用 docker 版本的 neo4j (v3.1.0)，我在使用 neo4j-shell.

连接到 neo4j 服务器时遇到困难

运行在 neo4r:3.1.0 docker 的一个实例之后，我运行一个 bash 在容器中：

$ docker exec -it neo4j /bin/bash

然后我尝试运行 neo4j-shell 像这样：

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

但它出错了：

$ /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开放端口：

$ 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，没有 1337 打开！我查看了配置文件，指定端口的行被注释掉了，这意味着它应该设置为默认值 (1337)。

谁能帮我用neo4j连接到neo4j-shell?

顺便说一句，neo4j 服务器已启动运行ning，我可以通过端口 :7474 使用它的 Web 访问。

在 3.1 中，shell 似乎默认未启用。

您需要在启用 shell 的情况下传递您自己的配置文件：

取消评论

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

（我发现 docker 中更改一个值的工作人员数量相当繁重，但是是的..）

或者使用新的cypher-shell：
