以安装3.7.28为例，步骤如下:
一、安装erlang
curl -s https://packagecloud.io/install/repositories/rabbitmq/erlang/script.rpm.sh | sudo bash yum install -y erlang erl -version
二、安装rabbitmq
wget https://dl.bintray.com/rabbitmq/all/rabbitmq-server/3.7.28/rabbitmq-server-3.7.28-1.el7.noarch.rpm yum install rabbitmq-server-3.7.28-1.el7.noarch.rpm ## 开启管理后台界面 rabbitmq-plugins enable rabbitmq_management ## 必须执行，否则会导致启动rabbitmq-server失败 chown rabbitmq:rabbitmq /var/lib/rabbitmq/.erlang.cookie
三、rabbitmq常用命令
#前台启动服务 rabbitmq-server #后台启动服务 rabbitmq-server -detached #停止服务 rabbitmqctl stop #查看状态 rabbitmqctl status
四、rabbitmq添加用户
#添加账户，用户名test 密码123456 rabbitmqctl add_user test 123456 #授予用户角色，总共有四种角色，这里授予的是administrator rabbitmqctl set_user_tags test administrator #设置用户允许访问的vhost rabbitmqctl set_permissions -p / test '.*' '.*' '.*'
