- 执行erl命令么,出现erlang相关信息则表示安装成功

防火墙需开放5672（AMQP） 15672（WEB）端口
相关命令
systemctl start rabbitmq-server
rabbitmqctl status //查看启动状态
rabbitmqctl stop //关闭服务
rabbitmq-server -detached //进入mq目录，启动rabbitmq，-detached代表后台守护进程方式启动
rabbitmqctllist_users //查看角色
启动web访问rabbitmq插件
rabbitmq-plugins enable rabbitmq_management
默认guest用户不能通过web端访问，需新建用户
rabbitmqctl add_user admin 123 //admin为用户名 123为密码
rabbitmqctl set_user_tags admin administrator //给用户赋角色
修改rabbitmq配置
cp /usr/share/doc/rabbitmq-server-3.6.10/rabbitmq.config.example /etc/rabbtimq/rabbitmq.config
安装消息延迟插件
wget https://dl.bintray.com/rabbitmq/community-plugins/3.6.x/rabbitmq_delayed_message_exchange/rabbitmq_delayed_message_exchange-20171215-3.6.x.zip
unzip rabbitmq_delayed_message_exchange-20171215-3.6.x.zip -d /usr/lib/rabbitmq/lib/rabbitmq_server-3.6.10/plugins
rabbitmq-plugins enable rabbitmq_delayed_message_exchange
重启rabbitMq用户丢失解决
原因：RabbitMQ数据是根据当前hostname作为node节点作为数据名保存
数据路径：/var/lib/rabbitmq/mnesia/
可以通过添加RabbitMQ固定节点名字为info，保证数据文件不变
echo 'NODENAME=rabbit@info' | sudo tee -a /etc/rabbitmq/rabbitmq-env.conf
设置开机启动
systemctl enable rabbitmq-server.service
