docker部署rabbitmq集群的实现方法

docker pull rabbitmq:3.7-rc-management

# docker network create rabbitmqnet
# docker network ls
NETWORK ID     NAME        DRIVER       SCOPE
65b44ea8847c    rabbitmqnet     bridge       local

# docker run -d --name=rabbitmq1 -p 5672:5672 -p 15672:15672 -e RABBITMQ_NODENAME=rabbitmq1 -e RABBITMQ_ERLANG_COOKIE='YZSDHWMFSMKEMBDHSGGZ' -h rabbitmq1 --net=rabbitmqnet rabbitmq:3.7-rc-management

# docker run -d --name=rabbitmq2 -p 5673:5672 -p 15673:15672 -e RABBITMQ_NODENAME=rabbitmq2 -e RABBITMQ_ERLANG_COOKIE='YZSDHWMFSMKEMBDHSGGZ' -h rabbitmq2 --net=rabbitmqnet rabbitmq:3.7-rc-management

# docker run -d --name=rabbitmq3 -p 5674:5672 -p 15674:15672 -e RABBITMQ_NODENAME=rabbitmq3 -e RABBITMQ_ERLANG_COOKIE='YZSDHWMFSMKEMBDHSGGZ' -h rabbitmq3 --net=rabbitmqnet rabbitmq:3.7-rc-management

### Disk Node
# docker exec rabbitmq2 bash -c "rabbitmqctl stop_app && rabbitmqctl reset && rabbitmqctl join_cluster rabbitmq1@rabbitmq1 && rabbitmqctl start_app"

### Ram Node
# docker exec rabbitmq3 bash -c "rabbitmqctl stop_app && rabbitmqctl reset && rabbitmqctl join_cluster --ram rabbitmq1@rabbitmq1 && rabbitmqctl start_app"

# docker exec rabbitmq3 bash -c "rabbitmqctl stop_app && rabbitmqctl reset && rabbitmqctl start_app"

# docker pull haproxy

# cat haproxy-create.sh
#! /bin/bash

docker run -d   --name rabbitmq-haproxy   -p 1080:80 -p 5677:5677 -p 8001:8001   --net=rabbitmqnet   -v /root/rabbitmq/haproxy-etc:/usr/local/etc/haproxy:ro   haproxy:latest

root@node0:~/rabbitmq# cat haproxy-etc/haproxy.cfg
# Simple configuration for an HTTP proxy listening on port 80 on all
# interfaces and forwarding requests to a single backend "servers" with a
# single server "server1" listening on 127.0.0.1:8000

global
  daemon
  maxconn 256

defaults
  mode http
  timeout connect 5000ms
  timeout client 5000ms
  timeout server 5000ms

listen rabbitmq_cluster
  bind 0.0.0.0:5677
  option tcplog
  mode tcp
  balance leastconn
  server rabbit1 rabbitmq1:5672 check inter 2s rise 2 fall 3
  server rabbit2 rabbitmq2:5672 check inter 2s rise 2 fall 3
  server rabbit3 rabbitmq3:5672 check inter 2s rise 2 fall 3

listen http_front
  bind 0.0.0.0:80
  stats uri /haproxy"text-align: center">

获取haproxy的状态：http://external-ip:1080/haproxy"text-align: center">
rabbitmq exporter部署
要收集rabbitmq的metrics给prometheus使用的话，可以使用开源的rabbitmq-exporter
参考如下：
https://github.com/kbudde/rabbitmq_exporter
https://hub.docker.com/r/kbudde/rabbitmq-exporter/
拉取镜像


# docker pull kbudde/rabbitmq-exporter


启动rabbitmq实例
复制代码 代码如下:# docker run -d --name=rabbitmq1 -p 5672:5672 -p 15672:15672 -e RABBITMQ_NODENAME=rabbitmq1 -e RABBITMQ_ERLANG_COOKIE='YZSDHWMFSMKEMBDHSGGZ' -h rabbitmq1 --net=rabbitmqnet -p 9090:9090 rabbitmq:3.7-rc-management
开启9090端口，这个是rabbitmq exporter的默认PUBLISH_PORT
启动rabbitmq exporter实例


# docker run -d --net=container:rabbitmq1 kbudde/rabbitmq-exporter


获取rabbitmq的metrics


# wget http://localhost:9090/metrics
