第一步:创建集群目录

[root@node001 ~]# mkdir -p /usr/local/activemqCluster

复制单点至集群目录

[root@node001 ~]# cp /usr/local/activemq/apache-activemq-5.14.5 /usr/local/activemqCluster/mq1 -rf

第二步：配置activemq.xml

进入conf所在目录

[root@node001 ~]# cd /usr/local/activemqCluster/mq1/conf

[root@node001 conf]# vi activemq.xml

替换为下面的内容：

配置详细信息解读：

         
      
     
     
          #配置自动切换地址    
      
     

 

第三步：再复制两份，共计三份，修改端口号

[root@node001 ~]# cd /usr/local/activemqCluster/

[root@node001 activemqCluster]# cp mq1 mq2 -rf

[root@node001 activemqCluster]# cp mq1 mq3 -rf

mq2修改端口号

[root@node001 activemqCluster]# cd mq2/conf

[root@node001 conf]# vi activemq.xml 

mq3修改端口号同理,改为61816即可，此处不在演示

第四步：启动

[root@node001 ~]# cd /usr/local/activemqCluster/

[root@node001 activemqCluster]# mq1/bin/activemq start

java客户端操作集群

更改连接地址即可，如图：
