centos7安装rabitmq，开启mqtt

1、安装 Erlang

RabbitMQ 依赖于 Erlang，因此首先需要安装 Erlang。打开终端并执行以下命令：

sudo yum install -y https://packages.erlang-solutions.com/erlang-solutions-2.0-1.noarch.rpm
sudo yum install -y erlang

安装socat

yum install socat -y 

安装rabbitmq-server-

rpm -ivh rabbitmq-server-3.8.17-1.el7.noarch.rpm

启动或停止

sudo systemctl start rabbitmq-server

sudo systemctl stop rabbitmq-server

检查RabbitMQ状态

sudo systemctl status rabbitmq-server

设置开机启动

sudo systemctl enable rabbitmq-server

启用mqtt插件

rabbitmq-plugins enable rabbitmq_mqtt

新增用户

# 这个是查看rabbitmq下面有多少用户
rabbitmqctl list_users

# 增加账户admin并在设置admin的密码
rabbitmqctl add_user admin 密码

# 设置admin的角色为管理员
rabbitmqctl set_user_tags admin administrator

# 设置admin的权限
rabbitmqctl set_permissions -p "/" admin ".\*" ".\*" ".\*"

修改mqtt端口

vi /etc/rabbitmq/rabbitmq.conf

#添加配置，参考https://www.rabbitmq.com/docs/mqtt#config
mqtt.listeners.tcp.default = 1883
