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

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

$ docker exec -it neo4j /bin/bash

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

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

But it errors:

$ /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

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

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).

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

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

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

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

Uncomment

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

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

Or use the new cypher-shell : 

ikwattro@graphaware-team ~> docker ps -a | grep 'neo4j'

Type :help for a list of available commands or :exit to exit the shell.

-

neo4j> :begin
neo4j# create (n:Person {name:"John"});
Added 1 nodes, Set 1 properties, Added 1 labels
neo4j# :rollback
neo4j> :commit
There is no open transaction to commit
