Move rabbit's clustering port away from the ephemeral port range
Currently RabbitMQ cluster uses a predefined port 35672 for clustering.
This port belongs to so-called ephemeral ports range.
Ephemeral ports are the ports kernel assings to application if it
doesn't specify which port to open. So there is a small chance that this
application being started before RabbitMQ itself could grab this port.
While rather unlikely we did see this happen.
Selinux change should already be in place. On my Centos 7 we have:
rabbitmq_port_t tcp 25672
corenet_tcp_bind_rabbitmq_port(rabbitmq_t)
corenet_tcp_connect_rabbitmq_port(rabbitmq_t)
