如何部署activemq以及部署时遇到的相关问题

部署

以centos为例，下载jar包，tar -zxvf xxx解压后，进入activemq解压文件夹，执行./bin/activemq console即可在shell前端启动，想后台运行的话执行./bin/activemq start即可。

官方文档在这里，很简单：http://activemq.apache.org/getting-started

遇到的问题

1、activemq启动失败，报错

报错信息如下：

Caused by: java.lang.IllegalStateException: BeanFactory not initialized or already closed - call 'refresh' before accessing beans via the ApplicationContext

解决

• 1.确认计算机主机名名称没有下划线

  • centos修改主机名可以参考这篇 https://www.cnblogs.com/mingyue5826/p/11528121.html

• 2.如果是win7，停止ICS(运行–>services.msc找到Internet Connection Sharing (ICS)服务,改成手动启动或禁用)

2、部署在VPS或是虚拟机上，也关闭了防火墙，但无法访问web页面xx.xx.xx.xx:8161/admin

修改conf/jetty.xml，注释掉host属性这行：

​
<bean id="jettyPort" class="org.apache.activemq.web.WebConsolePort" init-method="start">
           <!--默认是127.0.0.1， 注释掉这一行-->
        <!-- <property name="host" value="127.0.0.1"/> -->
        <property name="port" value="8161"/>
</bean>

重新启动activemq即可
