2. 环境准备
    安装socat：yum -y install socat
    安装编译环境：yum -y install make gcc gcc-c++ kernel-devel m4 ncurses-devel openssl-devel unixODBC unixODBC-devel httpd python-simplejson
3. 安装erlang 和 rabbitmq
    安装erlang：rpm -ivh erlang-22.0.7-1.el7.x86_64.rpm
    安装rabbitmq：rpm -ivh rabbitmq-server-3.8.14-1.el7.noarch.rpm
4. 安装插件
   1. 插件存放路径
       /usr/lib/rabbitmq/lib/rabbitmq_server-3.7.18/plugins
   2. 查看插件
       rabbitmq-plugins list
   3. web插件安装
       rabbitmq-plugins enable rabbitmq_management
   4. 延迟队列安装
       下载地址：https://www.rabbitmq.com/community-plugins.html
       上传到 /usr/lib/rabbitmq/lib/rabbitmq_server-3.7.18/plugins
       安装延迟队列插件：rabbitmq-plugins enable rabbitmq_delayed_message_exchange
5. 处理配置文件
   1. copy配置文件 cp /usr/share/doc/rabbitmq-server-3.7.18/rabbitmq.config.example /etc/rabbitmq/
   2. 重命名：cp rabbitmq.config.example rabbitmq.config
   3. 修改配置：vim rabbitmq.config
      
6. 启动rabbitmq
     systemctl start|stop| rabbitmq-server.service
7. 自启动
    systemctl enable rabbitmq-server

集群版安装

1. 编写 /etc/hosts

192.168.10.101	mqmaster
192.168.10.101	mqslave
192.168.10.101	mqslave

2. 按单机版在三台机器上安装rabbitmq
3. 修改其他节点服务器的.erlang.cookie 保证所有服务器的 .erlang.cookie文件保持一致
    a.修改文件权限：chmod 777 /var/lib/rabbitmq/.erlang.cookie
    b.将主服务器.erlang.cookie文件内容复制到其他服务器.erlang.cookie，修改完之后将权限改回400：chmod 400 /var/lib/rabbitmq/.erlang.cookie
4. 配置服务
    a.启动各服务节点Rabbitmq服务：systemctl start rabbitmq-server.service
    b.其他节点加入集群

rabbitmqctl stop_app
rabbitmqctl join_cluster rabbit@mqmaster
rabbitmqctl start_app

5. 配置用户【主服务器配置】

rabbitmqctl add_user admin admin123
rabbitmqctl add_user admin_client 092c216d8fc7ce83d3db
rabbitmqctl set_user_tags admin administrator
rabbitmqctl set_user_tags admin_client management
rabbitmqctl set_permissions -p "/" admin ".*" ".*" ".*"
rabbitmqctl set_permissions -p "/" admin_client ".*" ".*" ".*"
rabbitmqctl list_users

6. 注意：
    a.服务器之间添加防火墙白名单：可参考https://blog.youkuaiyun.com/CMLXZL/article/details/115702895?spm=1001.2014.3001.5501
