一、创建rabbitmq的data目录
二、创建.erlang.cookie文件（集群cookie用）
三、创建haproxy.cfg配置文件
四、创建docker-compose.yml文件
五、启动docker-compose.yml文件
六、创建加入集群的shell脚本，并执行
#!/bin/bash
#reset first node
echo "Reset first rabbitmq node."
docker exec rabbit1 /bin/bash -c 'rabbitmqctl stop_app'
docker exec rabbit1 /bin/bash -c 'rabbitmqctl reset'
docker exec rabbit1 /bin/bash -c 'rabbitmqctl start_app'
docker exec rabbit1 /bin/bash -c 'rabbitmq-plugins enable rabbitmq_management'
docker exec rabbit1 /bin/bash -c 'echo management_agent.disable_metrics_collector = false > /etc/rabbitmq/conf.d/management_agent.disable_metrics_collector.conf'
#build cluster
echo "Starting to build rabbitmq cluster with two ram nodes."
docker exec rabbit2 /bin/bash -c 'rabbitmqctl stop_app'
docker exec rabbit2 /bin/bash -c 'rabbitmqctl reset'
docker exec rabbit2 /bin/bash -c 'rabbitmqctl join_cluster --ram rabbit@rabbit1'
docker exec rabbit2 /bin/bash -c 'rabbitmqctl start_app'
docker exec rabbit2 /bin/bash -c 'rabbitmq-plugins enable rabbitmq_management'
docker exec rabbit2 /bin/bash -c 'echo management_agent.disable_metrics_collector = false > /etc/rabbitmq/conf.d/management_agent.disable_metrics_collector.conf'
docker exec rabbit3 /bin/bash -c 'rabbitmqctl stop_app'
docker exec rabbit3 /bin/bash -c 'rabbitmqctl reset'
docker exec rabbit3 /bin/bash -c 'rabbitmqctl join_cluster --ram rabbit@rabbit1'
docker exec rabbit3 /bin/bash -c 'rabbitmqctl start_app'
docker exec rabbit3 /bin/bash -c 'rabbitmq-plugins enable rabbitmq_management'
docker exec rabbit3 /bin/bash -c 'echo management_agent.disable_metrics_collector = false > /etc/rabbitmq/conf.d/management_agent.disable_metrics_collector.conf'
#check cluster status
echo "ok"七、重启docker-compose.yml文件
作用是使shell脚本中开启的管理代理的度量收集功能生效。
八、访问rabbitmq控制台
查看集群情况。可以看到集群成功。
九、访问haproxy统计页面
