前言
本小節(jié)我們學習一下使用Docker部署RabbitMQ集群真竖。

拉取rabbitmq鏡像
docker pull rabbitmq:3.8-rc-management
若不使用Rabbitmq的management功能，可以拉取鏡像：rabbitmq:3.8-rc
創(chuàng)建Rabbitmq共享網(wǎng)絡
docker network create rabbitmqnet

組建rabbitmq集群
登陸Rabbitmq的后兩個節(jié)點厌小，執(zhí)行命令加入第一個Rabbitmq節(jié)點集群
### 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"
登錄：http://你的公網(wǎng)IP:15672 恢共，使用
rabbitmq1-Dustyone/bai5331359登錄,登錄其他節(jié)點，訪問相應的端口并使用相應的用戶名/密碼登錄即可
退出集群
# docker exec rabbitmq3 bash -c \
"rabbitmqctl stop_app && \
rabbitmqctl reset && \
rabbitmqctl start_app"
拉取haproxy鏡像
docker pull haproxy
創(chuàng)建目錄
/workspace/rabbitmq/haproxy-etc,并在該路徑下創(chuàng)建haprox.cfg配置文件
[root@iZ2ze8sm5upgi8z1dcazqeZ haproxy-etc]# pwd
/workspace/rabbitmq/haproxy-etc
[root@iZ2ze8sm5upgi8z1dcazqeZ haproxy-etc]# tree
.
└── haproxy.cfg
0 directories, 1 file
[root@iZ2ze8sm5upgi8z1dcazqeZ haproxy-etc]#
haproxy.cfg配置信息如下：
#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

拉取haproxy鏡像
docker pull haproxy
啟動haproxy
docker run -d \
--name rabbitmq-haproxy \
-p 8002:8002 -p 5677:5677 -p 8001:8001 \
--net=rabbitmqnet \
-v /workspace/rabbitmq/haproxy-etc:/usr/local/etc/haproxy:ro \
haproxy:latest
啟動haproxy后璧亚，可以通過haproxy來訪問rabbitmq集群：http://你的公網(wǎng)IP:8001
獲取haproxy的狀態(tài)：http://你的公網(wǎng)IP:8002/haproxy?stats

將rabbitmq2和rabbitmq3兩個節(jié)點加入rabbitmq1節(jié)點以形成集群。
### Disk Node
docker exec rabbitmq2 bash -c \
"rabbitmqctl stop_app && \
rabbitmqctl reset && \
rabbitmqctl join_cluster rabbitmq1@rabbitmq1 && \
rabbitmqctl start_app"

rabbitmqctl reset && \
rabbitmqctl join_cluster --ram rabbitmq1@rabbitmq1 && \
rabbitmqctl start_app"

訪問http://你的公網(wǎng)IP:8002
如此便完成了使用docker-compose部署Rabbitmq集群
啟動停止Rabbitmq-Cluster建議使用如下Command
docker-compose up -d
docker-compose stop
此類方法部署RabbitMQ集群有很多細節(jié)癣蟋，便不一一說明了透硝，挑幾個重用的說一下
所有的節(jié)點最好共享一個網(wǎng)絡塊
執(zhí)行docker-compose.yml之前要創(chuàng)建好所有的配置文件
