SET architecture design: Based Cluster
While two clusters, data synchronization if necessary, then by the Federation of node3 cluster and a cluster node1 II can synchronize data, the data can be synchronized by mirroring the queue in the cluster.
Implementation: data synchronization via plug Federation
1, ready environment: + centos7 virtual machine installed rabbitmq
Two nodes: 192.168.2.208, 192.168.2.209
2, start the service service rabbitmq-server start & Enable or background
3, enable the Federation management plug
rabbitmq-plugins enable rabbitmq_federation
rabbitmq-plugins enable rabbitmq_federation_management
4, access http://192.168.2.209:15672/#/users control station will appear as shown:
5, the upstream node selected 192.168.208, 192.168.2.209 a downstream node:
In operation 192.168.2.209 downstream node:
(1) Create a switch, and a binding queue
(2) http://192.168.2.209:15672/#/users control station click Federation Upstreams,
Build relationships with the upstream node:
Next, click polices, add a policy:
(3) After adding the exchange and observation queue:
Click Federation status:
Open upstream node 192.168.2.208:
Open Connections:
Open exchange, more than a gray, which is a federation of channels, can not be used to send messages, as well as just created test.exchange switch:
6, sends a message Test
Send a message to the upstream node 192.168.2.208 test.exchange
To see whether the downstream nodes can be synchronized to the message 192.168.2.209.
如果在192.168.2.208上也想接收该消息并消费，在208上新建一个队列与该test.exchange建立绑定即可。这样就可以实现多中心的数据同步。
