ActiveMQ 没有正常关闭 -INFO：定期关闭不成功，发送 SIGKILL 到进程

Question

每当我尝试停止安装在 RHEL 服务器上的 ActiveMQ 时，它都不会正常停止。有谁知道为什么？我不确定为什么它会尝试连接到如下所示的 JMX 代理并失败。我需要什么来解决这些问题？

Answer 1

不知道这是否是您的问题，但在阅读后听起来好像 activemq 使用 jmx 作为其关闭挂钩，但是 activemq 附带的默认配置没有设置 jmx 连接器。

对我来说，如果我改变了，activemq 能够关闭：

        <managementContext>
            <managementContext createConnector="false"/>
        </managementContext>

要指定一个 jmx 连接器端口：

        <managementContext>
            <managementContext connectorPort="1099"/>
        </managementContext>
