Brief overview:
RabbitMQ is an open source implementation based on the Erlang language that follows the AMQP protocol and supports multiple clients (languages). It is used to store and forward messages in a distributed system, and has the characteristics of high availability, high scalability, and ease of use.
One, install RabbitMQ

2: Environment preparation: CentOS8.x+ / Erlang
RabbitMQ is developed in Erlang language, so the system environment must provide Erlang environment, the first step is to install Erlang

RabbitMQ configuration
RabbitMQ has a configuration file by default, which defines the relevant configuration information of RabbitMQ, which can meet daily development needs by default. If you need to modify it, you need to create a configuration file to cover it.

RabbitMQWeb management interface and authorized operation
Management interface
1. By default, rabbitmq does not have a client plug-in installed on the web, and it needs to be installed to take effect.
rabbitmq-plugins enable rabbitmq_management
Note: Rabbitmq has a default account and password: guest By default, it can only be accessed under localhost, so you need to add a remote login user.
After the installation is complete, restart the service.
Remember to open port 15672 in the security group of the corresponding server (Alibaba Cloud, Tencent Cloud, etc.).
Visit
http://ip:15672/ in the browser as follows:
authorized account and password
1. Add user
rabbitmqctl add_user admin admin
2. Set user assignment operation authority
rabbitmqctl set_user_tags admin administrator
user level:
1. The administrator can log in to the console, view all information, and manage rabbitmq.
2. The monitoring monitor can log in to the console to view all information.
3. The policymaker can log in to the console and specify the strategy.
4. Managment . Ordinary administrator can log in to the console.
3. Add resource permissions for users
rabbitmqctl.bat set_permissions -p / admin ".*" ".*" ".*"
rabbitmqctl add_user 账号 密码rabbitmqctl set_user_tags 账号 administratorrabbitmqctl change_password Username Newpassword 修改密码rabbitmqctl delete_user Username 删除用户rabbitmqctl list_users 查看用户清单rabbitmqctl.bat set_permissions -p / 用户名 ".*" ".*" ".*" 为用户设置administrator角色rabbitmqctl.bat set_permissions -p / root ".*" ".*" ".*"
Docker installation of RabbitMQ
Docker install RabbitMQ
1. Virtualized container technology-Docker installation
（1）yum 包更新到最新> yum update
（2）安装需要的软件包， yum-util 提供yum-config-manager功能，另外两个是devicemapper驱动依赖的> yum install -y yum-utils device-mapper-persistent-data lvm2
（3）设置yum源为阿里云> yum-config-manager --add-repo http://mirrors.aliyun.com/docker-ce/linux/centos/docker-ce.repo
（4）安装docker> yum install docker-ce -y
（5）安装后查看docker版本> docker -v
(6) 安装加速镜像 sudo mkdir -p /etc/docker sudo tee /etc/docker/daemon.json <<-'EOF' { "registry-mirrors": ["https://0wrdwnn6.mirror.aliyuncs.com"] } EOF sudo systemctl daemon-reload sudo systemctl restart docker
1-3, install rabbitmq
