我注意到最近将 ActiveMQ 从 5.16.1 升级到 5.16.7 时出现一个问题，ActiveMQ Web 控制台无法启动，并出现以下异常。其他功能工作正常，但无法启动 Web 控制台。我这边的这次升级没有进行任何配置更改。
HTTP ERROR 503 Service Unavailable
URI: /***/web-console/
STATUS: 503
MESSAGE: Service Unavailable

根据下面的异常，我检查了文件路径和conf，其中上下文指向相应的路径并且文件可用。

我们是否需要添加任何配置更改才能启动 Web 控制台？
我也有同样的问题。问题是我在运行脚本 activemq 中将 ACTIVEMQ_HOME 环境变量设置为硬编码值。我的路径也有一个链接。我认为主要问题是您需要让脚本 activemq 使用 getActiveMQhome 来找出路径。当我删除导出 ACTIVEMQ_HOME 变量的行时，它获得了没有链接的正确路径。 ActiveMQ 运行良好。
