neo4j-shell连接拒绝了java.rmi.ConnectException

Question

我正确启动服务器:

〜/ Downloads/neo4j-community-3.2.1/bin $ ./neo4j start Active database:graph.db使用目录:home:
/home/user/Downloads/neo4j-community-3.2.1 config:

/home/user/Downloads/neo4j-community-3.2.1/run启动Neo4j.警告:允许最多1024个打开文件,建议最少40000个.请参阅Neo4j手册.开始neo4j(pid 29246).它位于 http:// localhost:7474 /可能会有短暂的延迟,直到服务器准备就绪.有关当前状态,请参见/home/user/Downloads/neo4j-community-3.2.1/logs/neo4j.log.

然后当我尝试启动neo4j-shell时:

〜/ Downloads/neo4j-community-3.2.1/bin $ ./neo4j-shell -v ERROR(-v表示扩展信息):连接被拒绝java.rmi.ConnectException:连接拒绝主机:localhost; 嵌套异常是:java.net.ConnectException:sun.rmi.transport.tcp.TCPEndpoint.newSocket(TCPEndpoint.java:619)在sun.rmi.transport.tcp.TCPChannel.createConnection(TCPChannel.java:216)处拒绝连接sun.rmi.transport.tcp.TCPChannel.newConnection(TCPChannel.java:202)at sun.rmi.server.UnicastRef.newCall(UnicastRef.java:342)at sun.rmi.registry.RegistryImpl_Stub.lookup(Unknown Source)在java.rmi.Naming.lookup(Naming.java:101)atg.neo4j.shell.impl.RmiLocation.getBoundObject(RmiLocation.java:191)at org.neo4j.shell.impl.RemoteClient.findRemoteServer(RemoteClient.java) :72)org.neo4j.shell.impl.RemoteClient.(RemoteClient.java:65)org.neo4j.shell.impl.RemoteClient.(RemoteClient.java:46)org.neo4j.shell.ShellLobby.newClient( ShellLobby.java:204)org.neo4j.shell.StartClient.startRemote(StartClient.java:358)org.neo4j.shell.StartClient.start(StartClient.java:229)atg.neo4j.shell.StartClient.main (StartClient.java:147)引起:java.net.ConnectException:Connect 在java.net.AbstractPocketSmplImpl.deConnect(AbstractPlainSocketImpl.java:350)java.net.AbstractPlainSocketImpl.connectToAddress(AbstractPlainSocketImpl.java:206)java.net.AbstractPlainSocketImpl上的java.net.PlainSocketImpl.socketConnect(Native Method)拒绝离子.connect(AbstractPlainSocketImpl.java:188)java.net.SocksSocketImpl.connect(SocksSocketImpl.java:392),java.net.Socket.connect(Socket.java:589),java.net.Socket.connect(Socket. java:538)at java.net.Socket.(Socket.java:434)at java.net.Socket.(Socket.java:211)at sun.rmi.transport.proxy.RMIDirectSocketFactory.createSocket(RMIDirectSocketFactory.java:40 )at sun.rmi.transport.proxy.RMIMasterSocketFactory.createSocket(RMIMasterSocketFactory.java:148)at sun.rmi.transport.tcp.TCPEndpoint.newSocket(TCPEndpoint.java:613)... 13更多

-host要连接的主机的域名或IP(默认值:localhost)-port要连接的主机端口(默认值:1337)-name RMI名称,即rmi://:/(默认值:shell)-pid进程ID连接到-c命令行以执行.执行后,shell退出-file文件,其中包含要执行的命令,或者' - '从stdin读取.执行后,shell退出-readonly以只读方式连接(仅用于连接-path)-path指向neo4j数据库路径,以便可以在那里启动本地服务器-config指向启动本地服务器时的配置文件

remote的示例参数:-port 1337 -host 192.168.1.234 -port 1337 -name shell -host localhost -readonly ...或者没有默认值的参数local的示例参数:-path/path/to/db -path/path/to/db -config /path/to/neo4j.config -path/path/to/db -readonly

服务器处于默认的初始配置,我唯一改变的是图形用户名和密码.

neo4j-shell自版本以来已弃用3.1,您应该使用cypher-shell.

但您可以通过添加此配置来启用它: dbms.shell.enabled=true

干杯.
