# RabbitMQ-Cluster-with-Mirrored-Queue

## Environments Preparation

### Three RabbitMq nodes

Three CentOS 7 VM. Hostname are: `controller1`, `controller2` and `controller3`, and make sure

you `/etc/hosts` configure right.

### Install RabbitMQ server

```

% yum install rabbitmq-server

```

## Create RabbitMQ cluster

### On controller1

Start RabbitMQ server on node controller1.

```

% service rabbitmq-server start

```

Copy the elang cookie from controller1 to the other nodes: controller2, controller3

```

% scp /var/lib/rabbitmq/.erlang.cookie root@controller2:/var/lib/rabbitmq/.erlang.cookie

% scp /var/lib/rabbitmq/.erlang.cookie root@controller3:/var/lib/rabbitmq/.erlang.cookie

```

### On controller2

Make sure that the cookie copy from controller1 is owned by user `rabbitmq`, group `rabbitmq` and has mode 400 on both node.

```

% chown rabbitmq:rabbitmq /var/lib/rabbitmq/.erlang.cookie

% chmod 400 /var/lib/rabbitmq/.erlang.cookie

```

Start the RabbitMQ service.

```

% chkconfig rabbitmq-server on

% service rabbitmq-server start

```

Join to a cluster.

```

% rabbitmqctl stop_app

Stopping node rabbit@controller2 ...

...done.

% rabbitmqctl join_cluster rabbit@controller1

Clustering node rabbit@controller2 with rabbit@controller1 ...

...done.

% rabbitmqctl start_app

Starting node rabbit@controller2 ...

...done.

```

### On controller3

Do the same thing as you do on controller2

Go to controller1, and run:

```

% rabbitmqctl cluster_status

Cluster status of node rabbit@controller1 ...

[{nodes,[{disc,[rabbit@controller1,rabbit@controller2,rabbit@controller3]}]},

 {running_nodes,[rabbit@controller3,rabbit@controller2,rabbit@controller1]},

 {cluster_name,<<"rabbit@controller1">>},

 {partitions,[]}]

...done.

```

## Set Policy for mirrored queue

### RabbitMQ Management tools

Enable rabbitmq managment plugin and restart it

```

% rabbitmq-plugins enable rabbitmq_management

% service rabbitmq-server restart

```

Go to http://controller1:15672/#/ to declare a queue named `127.0.0.1` on controller1.

### Set Policy for mirror queue

Policy where all queues are mirrored to all nodes in the cluster:

```

% rabbitmqctl set_policy ha-all "." '{"ha-mode":"all"}'

```

Then you will see the queue on controller2 and controller3.

## Install haproxy

```

% yum install haproxy

```

Edit /etc/haproxy/haproxy.cfg and create a simple TCP proxy for RabbitMQ.

```

global

    daemon

defaults

    mode tcp

    maxconn 10000

    timeout connect 5s

    timeout client 100s

    timeout server 100s

listen rabbitmq 10.15.85.141:5670

    mode tcp

    balance roundrobin

    server controller1 controller1:5672 check inter 5s rise 2 fall 3

    server controller2 controller2:5672 check inter 5s rise 2 fall 3

    server controller3 controller3:5672 check inter 5s rise 2 fall 3

```

```

% service haproxy start

```
