1. RabbitMQ installation starts

erlang download: https://dl.bintray.com/rabbitmq-erlang/rpm/erlang
socat download: http://repo.iotti.biz/CentOS/7/x86_64/socat-1.7.3.2-5.el7.lux.x86_64.rpm
RabbitMQ download: http://www.rabbitmq.com/install-rpm.html#downloads

2. Installation

root@localhost opt]# rpm -ivh erlang-21.3.8.16-1.el7.x86_64.rpm
[root@localhost opt]# rpm -ivh socat-1.7.3.2-5.el7.lux.x86_64.rpm
[root@localhost opt]# rpm -ivh rabbitmq-server-3.8.6-1.el7.noarch.rpm

3. Start the background management plugin

[root@localhost opt]# rabbitmq-plugins enable rabbitmq_management

4. Start RabbitMQ

The firewall must be closed to access the management platform

启动：[root@localhost opt]# systemctl start rabbitmq-server.service
[root@localhostopt]#systemctl status rabbitmq-server.service
[root@localhostopt]#systemctlrestartrabbitmq-server.service
[root@localhost opt]# systemctl stoprabbitmq-server.service

5. View progress

[root@localhost opt]# ps -ef | grep rabbitmq

6. Test
