RabbitMQ01 192.168.8.131
RabbitMQ02 192.168.8.132
RabbitMQ03 192.168.8.133
RabbitMQ04 192.168.8.134
2、RabbitMQ集群安装
（1）四个节点同时运行，下载RabbitMQ镜像
[~]# docker pull rabbitmq:3-management
（2）四个节点分别运行，启动RabbitMQ容器
[~]# docker run -d --restart=always --hostname rabbit01 --name rabbit-01 -p 25672:25672 -p 15672:15672 -p 5672:5672 -p 5671:5671 -p 4369:4369 --add-host rabbit02:192.168.8.132 --add-host rabbit03:192.168.8.133 --add-host rabbit04:192.168.8.134 -e RABBITMQ_ERLANG_COOKIE=‘rbmqcookie‘ rabbitmq:3-management
[~]# docker run -d --restart=always --hostname rabbit02 --name rabbit-02 -p 25672:25672 -p 15672:15672 -p 5672:5672 -p 5671:5671 -p 4369:4369 --add-host rabbit01:192.168.8.131 --add-host rabbit03:192.168.8.133 --add-host rabbit04:192.168.8.134 -e RABBITMQ_ERLANG_COOKIE=‘rbmqcookie‘ rabbitmq:3-management
[~]# docker run -d --restart=always --hostname rabbit03 --name rabbit-03 -p 25672:25672 -p 15672:15672 -p 5672:5672 -p 5671:5671 -p 4369:4369 --add-host rabbit01:192.168.8.131 --add-host rabbit02:192.168.8.132 --add-host rabbit04:192.168.8.134 -e RABBITMQ_ERLANG_COOKIE=‘rbmqcookie‘ rabbitmq:3-management
[~]# docker run -d --restart=always --hostname rabbit04 --name rabbit-04 -p 25672:25672 -p 15672:15672 -p 5672:5672 -p 5671:5671 -p 4369:4369 --add-host rabbit01:192.168.8.131 --add-host rabbit02:192.168.8.132 --add-host rabbit03:192.168.8.133 -e RABBITMQ_ERLANG_COOKIE=‘rbmqcookie‘ rabbitmq:3-management
（3）、将节点添加至集群服务中，我们将节点03设置为集群的master节点，其他为子节点，注意配置两个节点为ram节点，另两个为disc节点，执行时注意命令的不同
节点01上执行：
[~]# docker exec -it rabbit-01 bash
[]# rabbitmqctl stop_app
[]# rabbitmqctl reset
[]# rabbitmqctl join_cluster --ram
[]# rabbitmqctl start_app
[]# exit
节点02上执行：
[~]# docker exec -it rabbit-02 bash
[]# rabbitmqctl stop_app
[]# rabbitmqctl reset
[]# rabbitmqctl join_cluster --ram
[]# rabbitmqctl start_app
[]# exit
节点04上执行：
[~]# docker exec -it rabbit-01 bash
[]# rabbitmqctl stop_app
[]# rabbitmqctl reset
[]# rabbitmqctl join_cluster
[]# rabbitmqctl start_app
[]# exit
节点03上执行：
[~]# docker exec -it rabbit-03 bash
[]# rabbitmqctl stop_app
[]# rabbitmqctl reset
[]# rabbitmqctl start_app
[]# exit
3、配置添加ha-mode镜像
Name:HA
Pattern:.
Definition:ha-mode = all

3、安装配置nginx，以提供高可用
nginx的安装，这里略过，直接进入配置
[~]# cd /usr/local/nginx/conf
[~conf]# vi nginx.conf
其他配置略过
stream{
upstream rabbitmq{
server 192.168.8.131:5672 max_fails=2 fail_timeout=5s weight=2;
server 192.168.8.132:5672 max_fails=2 fail_timeout=5s weight=2;
server 192.168.8.133:5672 max_fails=2 fail_timeout=5s weight=2;
server 192.168.8.134:5672 max_fails=2 fail_timeout=5s weight=2;
}
server{
listen 5678;
proxy_pass rabbitmq;
}
}
[~conf]# vi rabbitmqstream.conf
upstream mqweb {
ip_hash;
server 192.168.8.131:15672;
server 192.168.8.132:15672;
server 192.168.8.133:15672;
server 192.168.8.134:15672;
}
server {
listen 80;
server_name localhost;
location / {
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 100m;
client_body_buffer_size 256k;
proxy_connect_timeout 60;
proxy_send_timeout 60;
proxy_read_timeout 60;
proxy_buffer_size 256k;
proxy_buffers 8 256k;
proxy_busy_buffers_size 512k;
proxy_temp_file_write_size 512k;
}
}
? 重新启动nginx容器
[~conf]# /usr/local/nginx/sbin/nginx -s reload
[~conf]# /usr/local/nginx/sbin/nginx -s stop
[~conf]# /usr/local/nginx/sbin/nginx
