我无法连接到 webadmin 控制台，但我可以连接到 shell 并向 Neo4j DB 写入密码查询。

日志上的错误是：

当我使用 lsof -i:7474 检查时，该端口上没有运行任何东西，唯一显示的是 Java 进程正在运行/正在绑定到套接字：

 COMMAND  PID USER   FD   TYPE DEVICE SIZE/OFF NODE NAME
    java    6465 root  114u  IPv6  49348      0t0  TCP localhost:7474 (LISTEN)

我终止进程并重新启动服务器，同样的事情不断发生。

这是怎么回事？
