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），并且在使用neo4j-shell连接到neo4j服务器时遇到困难。

运行 docker一个实例后，我跑在容器内一个bash：

$ docker exec -it neo4j /bin/bash 

从那里我尝试运行neo4j-shell这样的：

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

但它的错误：

$ /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）。由于没有工作，我想列出我的容器上的开放端口：

$ 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 

正如你可以看到有没有1337开放！我查看了配置文件，指定端口的行被注释掉了，这意味着它应该被设置为默认值（1337）。

任何人都可以帮助我连接到neo4j使用neo4j壳？

顺便说一句，neo4j服务器已启动并运行，我可以通过端口7474使用其Web访问。

3.1中似乎默认情况下没有启用shell。

您将需要通过自己的配置文件并启用了壳：

取消注释

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

（我发现工人在码头工人相当沉重改变一个值量，但是是啊..）

或者使用新的CYPHER壳：
