1. IP address planning (configure information to / etc/hosts)

Hostname IP address

RabbitMQ01 192.168.8.131

RabbitMQ02 192.168.8.132

RabbitMQ03 192.168.8.133

2. RabbitMQ cluster installation

(1) four nodes run at the same time to download RabbitMQ image

[root@RabbitMQ01~] # docker pull rabbitmq:3-management

(2) four nodes run separately to start the RabbitMQ container

[root@RabbitMQ01~] # docker run-d-- restart=always-- hostname rabbit01-- name rabbit-01-p 25672-p 15672-p 5672-p 5672-p 5671-p 4369-- add-host rabbit02:192.168.8.132-add-host rabbit03:192.168.8.133-- add-host rabbit04:192.168.8.134-e RABBITMQ_ERLANG_COOKIE='rbmqcookie' rabbitmq:3-management

(3) when adding nodes to the cluster service, we set node 03 as the master node of the cluster and the other as child nodes. Pay attention to the configuration of two nodes as ram nodes and the other two as disc nodes. Pay attention to the different commands when executing.

Execute on node 01:

[root@RabbitMQ01~] # docker exec-it rabbit-01 bash

[rabbit@rabbit01] # rabbitmqctl stop_app

[rabbit@rabbit01] # rabbitmqctl reset

[rabbit@rabbit01] # rabbitmqctl join_cluster-- ram rabbit@rabbit03

[rabbit@rabbit01] # rabbitmqctl start_app

[rabbit@rabbit01] # exit

Execute on node 02:

[root@RabbitMQ02~] # docker exec-it rabbit-02 bash

[rabbit@rabbit02] # rabbitmqctl stop_app

[rabbit@rabbit02] # rabbitmqctl reset

[rabbit@rabbit02] # rabbitmqctl join_cluster-- ram rabbit@rabbit03

[rabbit@rabbit02] # rabbitmqctl start_app

[rabbit@rabbit02] # exit

Execute on node 04:

[root@RabbitMQ04~] # docker exec-it rabbit-01 bash

[rabbit@rabbit04] # rabbitmqctl stop_app

[rabbit@rabbit04] # rabbitmqctl reset

[rabbit@rabbit04] # rabbitmqctl join_cluster rabbit@rabbit03

[rabbit@rabbit04] # rabbitmqctl start_app

[rabbit@rabbit04] # exit

Execute on node 03:

[root@RabbitMQ03~] # docker exec-it rabbit-03 bash

[rabbit@rabbit03] # rabbitmqctl stop_app

[rabbit@rabbit03] # rabbitmqctl reset

[rabbit@rabbit03] # rabbitmqctl start_app

[rabbit@rabbit03] # exit

3. Configure and add ha-mode image

Name:HA

Pattern:.

Definition:ha-mode = all

Installation and deployment of RabbitMQ Cluster based on docker in CentOS7.X Environment

Access the main interface after the cluster is started:

3. Install and configure nginx to provide high availability

The installation of nginx, which is skipped here, goes directly to the configuration

[root@nginx~] # cd / usr/local/nginx/conf

[root@nginx~conf] # vi nginx.conf

Skip other configurations
