RABBITMQ Cluster Environment Construction-4

Ensure the successful installation of JDK,ERLANG,RABBITMQ and so on, and RABBITMQ can start normally, multiple computers can ping each other through.

1. Installing erlang,rabbitmq

such as: 192.168.1.1, 192.168.1.2, 192.168.1.3 three nodes installed, and then turn on the RabbitMQ monitoring plug-in:

Rabbitmq-plugins Enable Rabbitmq_management Reference blog: Http://88250.b3log.org/rabbitmq-clustering-ha http://blog.csdn.net/gao715108023/article/details/11522889

2. Modify host name

Vi/etc/hosts Make sure that the contents of each host Hosts file are modified as follows: IP host name

such as: 10.111.56.134 Master
10.111.56.79 Slave5

3. Setting up Erlang cookies

Erlang Cookie file:/var/lib/rabbitmq/.erlang.cookie. Here will node1 the file copy to Node2, Node3, because this file permissions is 400, so you need to first modify the Node2, node3 the file permission is 777:

# chmod 777/var/lib/rabbitmq/.erlang.cookie

Then copy the file in Node1 to Node2, NODE3, and finally modify the permissions and the owning user/group back:

# chmod 400/var/lib/rabbitmq/.erlang.cookie # chown Rabbitmq/var/lib/rabbitmq/.erlang.cookie # CHGRP Rabbitmq/var/lib/rabbitmq/.erlang.cookie

Also ensure that the contents of the hidden file/root/.erlang.cookie are consistent, it is best to test the master node on the other node host.

4. Run each node using the -detached parameter

# Rabbitmqctl Stop # rabbitmq-server-detached

5. forming a cluster

Node2, Node3, and Node1 are organized into clusters:

Node2 # Rabbitmqctl Stop_app Node2 # rabbitmqctl Join_cluster [email protected] Node2 # Rabbitmqctl Start_app NODE3 # Rabbitmqctl Stop_app NODE3 # rabbitmqctl Join_cluster [email protected] NODE3 # Rabbitmqctl Start_app

To view the RABBITMQ process:

The cluster node is added.

Node2 and Node3 also automatically establish a connection, and if you want to use a memory node, you can use the

Node2 # rabbitmqctljoin_cluster --ram [email protected] Join the cluster.

After the cluster is configured, you can perform rabbitmqctlcluster_status on any node of RabbitMQ to see if the cluster configuration is successful.

6. Set the mirroring queue policy

Execute on any of the nodes:

# rabbitmqctl Set_policy ha-all "^" ' {"Ha-mode": "All"} '

All queues are set to the mirror queue, that is, the queues are copied to each node, and the state of each node remains.

After completing these 6 steps, the RabbitMQ high-availability cluster has been set up, and the last step is to build the equalizer.
