1、创建rabbit相关存储目录

mkdir -p /usr/local/rabbitmq/rabbitmq01 /usr/local/rabbitmq/rabbitmq02 /usr/local/rabbitmq/rabbitmq03

2、创建容器

docker run -d --hostname rabbit1 --name myrabbit1 -v /usr/local/rabbitmq/rabbitmq01:/var/lib/rabbitmq -p 15673:15672 -p 5673:5672 -e RABBITMQ_ERLANG_COOKIE='rabbitcookie' rabbitmq:3.8-management

docker run -d --hostname rabbit2 --name myrabbit2 -v /usr/local/rabbitmq/rabbitmq02:/var/lib/rabbitmq -p 15674:15672 -p 5674:5672 -e RABBITMQ_ERLANG_COOKIE='rabbitcookie' --link myrabbit1:rabbit1 rabbitmq:3.8-management

docker run -d --hostname rabbit3 --name myrabbit3 -v /usr/local/rabbitmq/rabbitmq03:/var/lib/rabbitmq -p 15675:15672 -p 5675:5672 -e RABBITMQ_ERLANG_COOKIE='rabbitcookie' --link myrabbit1:rabbit1 --link myrabbit2:rabbit2  rabbitmq:3.8-management

3、针对容器内部执行修改

（1）容器1更改

docker exec -it myrabbit1 /bin/bash #进入容器
rabbitmqctl stop_app #停止rabbitmq
rabbitmqctl reset #设置rabbitmq可更改
rabbitmqctl start_app #开启rabbitmq
rabbitmqctl delete_user guest #删除guest用户
rabbitmqctl add_user 用户名 密码 #创建用户
rabbitmqctl set_user_tags 用户名 administrator #增加权限

（2）容器2更改

docker exec -it myrabbit2 /bin/bash
rabbitmqctl stop_app
rabbitmqctl reset
rabbitmqctl join_cluster --ram rabbit@rabbit1 #加入cluster节点
rabbitmqctl start_app

（3）容器3更改

docker exec -it myrabbit3 /bin/bash
rabbitmqctl stop_app
rabbitmqctl reset
rabbitmqctl join_cluster --ram rabbit@rabbit1
rabbitmqctl start_app

（4）容器1更改权限

docker exec -it myrabbit1 /bin/bash #进入容器
rabbitmqctl set_policy ha-all "^" '{"ha-mode":"all"}' #添加vhosts策略
rabbitmqctl set_permissions -p / heosun '.*' '.*' '.*' #赋权

4、部署负载均衡

1、编辑nginxrabbitmq.conf

vim /usr/local/rabbitmq/nginxRabbitmq.conf
user  nginx;
worker_processes  1;

error_log  /var/log/nginx/error.log warn;
pid        /var/run/nginx.pid;


events {
    worker_connections  10240;
}


http {
    include       /etc/nginx/mime.types;
    default_type  application/octet-stream;

    log_format  main  '$remote_addr - $remote_user [$time_local] "$request" '
                      '$status $body_bytes_sent "$http_referer" '
                      '"$http_user_agent" "$http_x_forwarded_for"';

    access_log  /var/log/nginx/access.log  main;

    sendfile        on;
    #tcp_nopush     on;

    keepalive_timeout  65;

    #gzip  on;

        proxy_redirect          off;
        proxy_set_header        Host $host;
        proxy_set_header        X-Real-IP $remote_addr;
        proxy_set_header        X-Forwarded-For $proxy_add_x_forwarded_for;
        client_max_body_size    10m;
        client_body_buffer_size   128k;
        proxy_connect_timeout   5s;
        proxy_send_timeout      5s;
        proxy_read_timeout      5s;
        proxy_buffer_size        128k;
        proxy_buffers           4 64k;
        proxy_busy_buffers_size  128k;
        #rabbitmq管理界面
        upstream rabbitManage {
                server 192.168.1.6:15673;
                server 192.168.1.6:15674;
                server 192.168.1.6:15675;
        }
        server {
        listen       15672;
        server_name   192.168.1.6;
        location / {
            proxy_pass   http://rabbitManage;
            index  index.html index.htm;
        }

    }
}
stream{
        upstream rabbitTcp{
        server 192.168.1.6:5673;
        server 192.168.1.6:5674;
        server 192.168.1.6:5675;
    }

    server {
        listen 5672;
        proxy_pass rabbitTcp;
    }
}

（2）创建nginx负载均衡容器

docker run -it -d --name nginxRabbitmq -v /usr/local/rabbitmq/nginxRabbitmq.conf:/etc/nginx/nginx.conf  -v /etc/localtime:/etc/localtime --privileged --net=host nginx
