有什么问题可以加群大家一起交流

Docker安装

安装环境:Centos7

1.安装docker

 yum install -y docker

2.配置阿里云docker镜像服务

在阿里云容器镜像服务里有个镜像加速器,在里面可以得到私有的镜像加速地址

下面编辑docker镜像加速

vi /etc/docker/daemon.json

会得到如下内容

{}

下面来改造它

{
  "registry-mirrors": ["https://你的私有地址.mirror.aliyuncs.com"]
}

保存文件进行docker配置文件重载

sudo systemctl daemon-reload

3.配置docker开机启动

systemctl enable docker.service

4.启动docker

 

systemctl start docker.service

5.创建docker网卡

docker network create subnet=172.21.0.0/16 rabbitmqnet

安装docker-conpose

curl -L https://github.com/docker/compose/releases/download/1.21.1/docker-compose-`uname -s`-`uname -m` -o /usr/local/bin/docker-compose
chmod +x /usr/local/bin/docker-compose

完成后就可以使用docker-compose了

使用配置rabbitmq集群

1.编写yml文件

第一个集群服务器yml配置-ram存储模式

 

version: '3.6'
networks:
 rabbit:
  external:
   name: rabbitmqnet
services:
 rabbitmq:
  image: rabbitmq:management
  ports:
   - "4369:4369"
   - "5671:5671"
   - "25672:25672"
   - "5672:5672"
   - "15672:15672"
  container_name: rabbitmq1
  hostname: rabbitmq1
  networks:
   - rabbit
  environment:
   RABBITMQ_NODENAME: rabbitmq1
   RABBITMQ_ERLANG_COOKIE: CURIOAPPLICATION
  volumes:
   - ./rabbitmq.sh:/home/rabbitmq.sh

 

第二个集群服务器配置-ram存储模式

 

 

version: '3.6'
networks:
 rabbit:
  external:
   name: rabbitmqnet
services:
 rabbitmq2:
  image: rabbitmq:management
  ports:
   - "4369:4369"
   - "5671:5671"
   - "25672:25672"
   - "5672:5672"
   - "15672:15672"
  container_name: rabbitmq2
  hostname: rabbitmq2
  networks:
   - rabbit
  environment:
   RABBITMQ_NODENAME: rabbitmq2
   RABBITMQ_ERLANG_COOKIE: CURIOAPPLICATION
  volumes:
   - ./rabbitmq.sh:/home/rabbitmq.sh

 

第三个集群服务器配置-disk存储模式

 

version: '3.6'
networks:
 rabbit:
  external:
   name: rabbitmqnet
services:
 rabbitmq3:
  image: rabbitmq:management
  ports:
   - "4369:4369"
   - "5671:5671"
   - "25672:25672"
   - "5672:5672"
   - "15672:15672"
  container_name: rabbitmq3
  hostname: rabbitmq3
  networks:
   - rabbit
  environment:
   RABBITMQ_NODENAME: rabbitmq3
   RABBITMQ_ERLANG_COOKIE: CURIOAPPLICATION

如果是配置在同一台宿主服务器这三个文件可以写在一个文件里,直接生成三台集群服务器.

2.shell文件

如果想用ram存储就用第一个shell文件,用硬盘存储就用第二个shell文件

ram集群服务器shell文件

rabbitmqctl stop_app
rabbitmqctl reset
rabbitmqctl join_cluster --ram rabbitmq3@rabbitmq3
rabbitmqctl start_app

disk集群服务器shell文件

rabbitmqctl stop_app
rabbitmqctl reset
rabbitmqctl join_cluster rabbitmq3@rabbitmq3
rabbitmqctl start_app

完成配置

1.生成容器

docker-compose -f rabbitmq1.yml -d up
docker-compose -f rabbitmq2.yml -d up
docker-compose -f rabbitmq2.yml -d up

2.进入容器执行shell文件完成集群连接

chmow +x /home/rabbitmq.sh
./home/rabbitmq.sh

这样就完成了rabbitmq集群服务器的配置,超级简单吧!

以下是经常遇到的问题,百度来的,下面的内容来自 醇氧 的CSDN 博客

问题一:
docker-compose配置rabbitmq集群服务器_第1张图片

sudo rabbitmqctl join_cluster --ram rabbit@rabbitmq-node1
Clustering node rrabbit@rabbitmq-node1 with rabbit@rabbitmq-node1...
Error: unable to connect to nodes rabbit@rabbitmq-node1]: nodedown

DIAGNOSTICS
===========
attempted to contact: [rabbit@rabbitmq-node1]
rabbit@rabbitmq-node1:
  * unable to connect to epmd (port 4369) on rabbitmq-node1: nxdomain (non-existing domain)
current node details:
- node name: 'rabbitmqctl-526rabbitmq-node1'
- home dir: /var/lib/rabbitmq
- cookie hash: 50YO3zK+HJHos0tab1vHjg==

解决之道:
集群节点间需能互相访问,故每个集群节点的hosts文件应包含集群内所有节点的信息以保证互相解析

vim /etc/hosts
1 IP    rabbit@rabbitmq-node1
2 IP    rabbit@rabbitmq-node2
3 IP    rabbit@rabbitmq-node3

之后重启各节点中的rabbitmq


问题二:

cluster搭建起来后若在web管理工具中rabbitmq_management的Overview的Nodes部

“Node statistics not available”

说明在该节点上web管理插件还未启用。

直接在显示提示信息的节点上运行

 rabbitmq-plugins enable rabbitmq_management
Error: mnesia_unexpectedly_running

原因:忘记先停止stop_app
解决:

rabbitmqctl stop_app

问题三:

这里写图片描述

[rabbit@rabbitmq-node2 ~]$ sudo rabbitmqctl start_app
Starting node rabbit@rabbitmq-node2 ...
BOOT FAILED
===========
Error description:
   {error,{inconsistent_cluster,"Node rabbit@rabbitmq-node1  thinks it's clustered with node rabbit@rabbitmq-node1, but rabbit@rabbitmq-node2 disagrees"}}
Log files (may contain more information):
   /var/log/rabbitmq/[email protected]
   /var/log/rabbitmq/[email protected]
Stack trace:
   [{rabbit_mnesia,check_cluster_consistency,0},
    {rabbit,'-start/0-fun-0-',0},
    {rabbit,start_it,1},
    {rpc,'-handle_call_call/6-fun-0-',5}]
Error: {rabbit,failure_during_boot,
           {error,
               {inconsistent_cluster,
                   "Node rabbit@rabbitmq-node2 thinks it's clustered with node rabbit@rabbitmq-node1, but rabbit@rabbitmq-node2 disagrees"}}}

需要重置一下

[rabbit@rabbitmq-node2~]$  rabbitmqctl reset
Resetting node rabbit@rabbitmq-node2 ...
[rabbit@rabbitmq-node2~]$ rabbitmqctl start_app
Starting node rabbit@rabbitmq-node2 ...

问题四:

这里写图片描述

[root@redid-server01 mnesia]# rabbitmqctl join_cluster rabbit@rabbitmq-node2
Clustering node 'rabbit@redid-server01' with 'rabbit@rabbitmq-node2' ...
Error: {corrupt_or_missing_cluster_files,{error,enoent},{error,enoent}}
