Question： OpenNMS安装指南上写道：Please make sure your DNS settings for the OpenNMS server are correct. In case there is an incorrect or missing A Resource Record for the server, OpenNMS might not start correctly. The reason is that the Java security manager cannot be initialized and an RMI class loader disabled exception will be shown. 一开始没关注DNS 服务器这个事情，后来发现OpenNMS虽然能启动，但常常自己关闭，就发现了这个问题，指南上也写的清楚，就是会出现不能正确启动的错误。 Solution: 那就搭个服务器呗。现阶段我只是搭建了DNS 服务器，而没有做具体的IP和域名的映射工作，也能正常工作了，我打算若是再有问题就再做映射工作。主要是因为“基于通过URL引用导入请求位置”是OpenNMS的新的增强功能，不是OpenNMS必需的。 官方说明：DNS Importing 中文讲解： DNS配置及理论详解 使用bind配置DNS服务器—初级篇 搭建Bind DNS Server
