安装rabbitmq
下载Docker镜像
docker pull rabbitmq:3.7.12-management
安装RabbitMQ
mkdir rabbitmq
# node1 172.17.11.22
cd rabbitmq
vim hosts
#输入
172.17.11.22 rabbit1 rabbit1
172.17.11.23 rabbit2 rabbit2
sudo docker run -d \
--name rabbit1 \
-h rabbit1\
--log-opt max-size=10m \
--log-opt max-file=3 \
-v /root/rabbitmq:/var/lib/rabbitmq:z \
-v /root/rabbitmq/hosts:/etc/hosts \

加入集群
上述完成2个RabbitMQ节点的启动,后面是要将两个节点做成一个集群,现在讲rabbitmq1作为master,然后rabbitmq2加入到rabbitmq1中
# node2 处理
sudo docker exec -it rabbit2 /bin/bash
# 加入集群
rabbitmqctl stop_app
rabbitmqctl join_cluster [email protected]
rabbitmqctl start_app
使用删除方式处理时出现过以下问题
[email protected]:
* connected to epmd (port 4369) on localhost
* epmd reports node 'rabbit' running on port 25672
* TCP connection succeeded but Erlang distribution failed
* Hostname mismatch: node "[email protected]" believes its host is different. Please ensure that hostnames resolve the same way locally and on "[email protected]"
current node details:
- node name: '[email protected]'
- home dir: /Users/antares
- cookie hash: Sg08R8+G85EYHZ3H/9NUfg==
官网中有问题显示,但是具体情况很多,经过后续的分析,是因为在docker run时hostname的问题,所以在run时指定容器的hostname。也就是通过-h来指定hostname,根本问题就是HOSTNAME
解决方法,在Docker创建时,指定了/etc/hosts文件,但是启动docker时,应用里的hostname与hosts中指定的hostname不相同
1. echo $HOSTNAME 查看下当前的hostname 然后export HOSTNAME=*** 修改为/etc/hosts希望的名字
2. /etc/hostname中科院设置相应的数据
使用docker部署rabbitmq集群时,因为hostname不匹配,导致的问题,建议在run时加入参数-h来指定参数,保证hostname的正确性
配置nginx,来保证集群的可用性
配置文件如下:
server {
listen 443;
server_name rabbitmq.example.cn;
ssl on;
ssl_certificate cert/123.pem;
ssl_certificate_key cert/123.key;
ssl_session_timeout 5m;

#rabbitmq管理界面

#!!! stream 要和http一个层级
# rabbitmq Tcp监听
stream{

注意:stream要和http一个层级
