Adding nodes to RabbitMQ master node cluster - Restricted Security Area Surveillance 4.2

Add backup nodes to the RabbitMQ master node cluster to help you enable queue mirroring. This ensures that messages published to a queue are replicated to all mirrors.

1. On each node, right-click the RabbitMQ Command Prompt (sbin dir) application and select Run as administrator.
   This application is installed with RabbitMQ by default
2. To stop the node, execute the following command:
   Code

   rabbitmqctl stop_app

   
3. To add the node to the cluster, execute the following command:
   Code

   rabbitmqctl.bat join_cluster rabbit@<MasterNodeName>

   

   NOTE: <MasterNodeName> is case sensitive.
4. To restart the node, execute the following command:
   Code

   rabbitmqctl start_app

   

   NOTE: You can verify that the correct node has been added successfully by executing the following command:

   Code

   rabbitmqctl.bat cluster_status

   

   or through the RabbitMQ web interface at https://<node hostname>:15671.
5. Enable queue mirroring on each node to improve high-availability:
   1. On all the nodes, including the master node, open the RabbitMQ Command Prompt.
   2. Execute the following command:
      Code

      rabbitmqctl.bat set_policy ha-all "" "{""ha-mode"":""all"", ""ha-sync-mode"":""automatic""}"
