Neo4j下执行cypher-shell时，Connection refused问题解决？

　　不多说，直接上干货！

问题分析

　　（1）配置文件里的关于shell的配置打开了吗

 　  （2）为了更好的远程访问

解决办法一

# Enable a remote shell server which Neo4j Shell clients can log in to.
#dbms.shell.enabled=true
# The network interface IP the shell will listen on (use 0.0.0.0 for all interfaces).
#dbms.shell.host=127.0.0.1
# The port the shell will listen on, default is 1337.
#dbms.shell.port=1337

 　　必须启动neo4j，其实是可以不需执行bin/neo4j start的。

 

root@zhouls-virtual-machine:/usr/local/app/neo4j-community-3.2.0/bin# ls
cypher-shell  neo4j  neo4j-admin  neo4j-import  neo4j-shell  tools
root@zhouls-virtual-machine:/usr/local/app/neo4j-community-3.2.0/bin# ./cypher-shell
username: neo4j
password: ******
Connected to Neo4j 3.2.0 at bolt://localhost:7687 as user neo4j.
Type :help for a list of available commands or :exit to exit the shell.
Note that Cypher queries must end with a semicolon.

解决办法二（推荐）

 

# Enable a remote shell server which Neo4j Shell clients can log in to.
dbms.shell.enabled=true
# The network interface IP the shell will listen on (use 0.0.0.0 for all interfaces).
dbms.shell.host=0.0.0.0
# The port the shell will listen on, default is 1337.
dbms.shell.port=1337

root@zhouls-virtual-machine:/usr/local/app/neo4j-community-3.2.0/bin# ls
cypher-shell  neo4j  neo4j-admin  neo4j-import  neo4j-shell  tools
