Question

无法通过shell连接到本地服务器。

我安装了neo4j-community-2.1.6（没有任何修改），启动了服务器，然后想通过shell连接（如此处http://goo.gl/jI12RO所述）。我错过了什么？

这是我的控制台输出：

为什么shell尝试连接到主机172.24.46.19？关于http://goo.gl/R3iSzK的建议也无济于事。

更新1：

我在neo4j.properties中激活了远程shell：

# Enable shell server so that remote clients can connect via Neo4j shell.
remote_shell_enabled=true
# The network interface IP the shell will listen on (use 0.0.0 for all interfaces)
remote_shell_host=127.0.0.1
# The port the shell will listen on, default is 1337
remote_shell_port=1337

仍然没有成功：

$ neo4j start
Using additional JVM arguments:  -server -XX:+DisableExplicitGC -Dorg.neo4j.server.properties=conf/neo4j-server.properties -Djava.util.logging.config.file=conf/logging.properties -Dlog4j.configuration=file:conf/log4j.properties -XX:+UseConcMarkSweepGC -XX:+CMSClassUnloadingEnabled -XX:-OmitStackTraceInFastThrow

仍在尝试连接172.24.46.19。

我有类似的问题，将端口从1337更改为1338（您可以选择不同的端口号）修复它。

1. Stop neo4j server
2. Enable shell properties in neo4j.conf file
   # 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=1338
3. start neo4j server
4. Start shell
   root@ubuntu:/etc/neo4j# neo4j-shell -port 1338
   Welcome to the Neo4j Shell! Enter 'help' for a list of commands. Please note that neo4j-shell is deprecated and to be replaced by cypher-shell.
NOTE: Remote Neo4j graph database service 'shell' at port 1338

neo4j-sh (?)$

通过shell拒绝连接本地服务器（Neo4j 2.1.6）
