本文记录了一次解决Node远程访问异常的问题经历，包括错误信息、排查步骤及最终解决方案。问题表现为远程访问时出现java.rmi.NoSuchObjectException异常，通过调整/etc/hosts文件中Node的映射IP解决了该问题。

查看IP：hostname -i
127.0.0.1

manager机器：/etc/hosts设置
127.0.0.1 localhost localhost.localdomain localhost4 localhost4.localdomain4 db-004
::1 localhost localhost.localdomain localhost6 localhost6.localdomain6
node节点远程IP ubuntu-40

查看IP：hostname -i
127.0.0.1

我也越到此问题，我两台node，一台之前不正常，后来好了，另一台，访问的地址不对，不知道内部是怎么处理的。防火墙关掉也没用。

我现在把远程访问的node机器 hostname改了就可以了改为映射外网IP
外网IP hostname
hostname -i
显示外网IP

4.
对应的{0}就是你node配置里的ip或者外部ip. {1}就是对应的暴露端口，Mbean Port
