ActiveMQ共享存储集群部署

ActiveMQ是什么：ActiveMQ是消息中间件，是一种在分布式系统中应用程序借以传递消息的媒介，主要解决应用耦合，异步消息等
特点：多语言编写，spring支持，多种传输协议，支持AJAX
消息形式：点对点，一对多(发布，订阅)
持久化：默认为文本模式

• 三台服务器操作
  下载apache-activemq-5.15.4-bin.tar.gz
  tar -zxf apache-activemq-5.15.4-bin.tar.gz
  cp -r apache-activemq-5.15.4 /usr/local/activemq-5.15.4
  cd /usr/local/activemq-5.15.4
  vim conf/activemq.xml
  hostname要写本主机IP

查到这一行，三台服务全都修改一样
brokerName="activemqCluster"

• 所有节点启动
  cd /usr/local/activemq-5.15.4/bin
  ./activemq start #注意查看data目录下的log,如果有异常排错
  进入zookeeper目录，查看MQ是否添加
  cd /usr/local/zookeeper-3.5.3/bin/
  ./zkCli.sh
