docker部署rabbitmq集群的实现方法

拉取rabbitmq management镜像

docker pull rabbitmq:3.7-rc-management

若不使⽤Rabbitmq的management功能，可以拉取镜像：rabbitmq:3.7-rc创建⽹络

创建rabbitmq私有⽹络

# docker network create rabbitmqnet# docker network ls

NETWORK ID NAME DRIVER SCOPE65b44ea8847c rabbitmqnet bridge local...

创建节点

通过docker命令创建三个Rabbitmq nodes；

注意这⾥使⽤相同的 RABBITMQ_ERLANG_COOKIE 值

# 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

组建rabbitmq集群

登陆Rabbitmq的后两个节点，执⾏命令加⼊第⼀个Rabbitmq节点集群

### 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\"

退出集群

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

拉取haproxy镜像拉取haproxy镜像

# docker pull haproxy

启动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

haproxy的配置⽂件如下：

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 127.0.0.1:8000global daemon

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：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 9090:9090rabbitmq: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
