If the page appears /etc/rabbitmq/rabbitmq.config(not found)
The solution is as follows: find / -name "rabbitmq.config.example" to find the corresponding template configuration file to copy
cp /usr/share/doc/rabbitmq-server-3.6.6/rabbitmq.config.example /etc/rabbitmq/
mv rabbitmq.config.example rabbitmq.config
service rabbitmq-server restart
