Rabbitmq的RPM包安装

## 下载
wget --content-disposition "https://packagecloud.io/rabbitmq/erlang/packages/el/7/erlang-21.3.8.18-1.el7.x86_64.rpm/download.rpm?distro_version_id=140"

##
wget --content-disposition "https://packagecloud.io/rabbitmq/rabbitmq-server/packages/el/7/rabbitmq-server-3.8.29-1.el7.noarch.rpm/download.rpm?distro_version_id=140"

###
rpm --import https://www.rabbitmq.com/rabbitmq-release-signing-key.asc

默认账号密码：guest/guest，rabbitmq 从 3.3.0 开始禁止使用 guest/guest 权限通过除 localhost 外的访问。

创建后创建用户相关命令

## 创建用户,第二个knight 为密码
rabbitmqctl add_user knight knight

##设置用户分配操作权限
rabbitmqctl set_user_tags knight administrator

##
rabbitmqctl set_permissions -p / knight ".*" ".*" ".*"

##
systemctl status rabbitmq-server

## 开启 web 访问
rabbitmq-plugins enable rabbitmq_management
