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
