Virtual host

Each Rabbit can create a lot of vhost, which we call virtual hosts. Each virtual host is actually a mini version of RabbitMQ, with its own queues, switches and bindings, and its own permission mechanism.

Vhost features:

RabbitMQ default vhost is "/" out of the box; multiple vhost are isolated, multiple vhost cannot communicate, and do not have to worry about naming conflicts (queues and switches and bindings), achieving multi-layer separation; vhost must be specified when creating users List all virtual hosts: rabbitmqctl list_vhosts list all permissions on the virtual host: rabbitmqctl list_permissions-p [vhost_name] create virtual host: rabbitmqctl add_vhost [vhost_name] delete virtual host: rabbitmqctl delete_vhost [vhost_name] user management add user: rabbitmqctl add_user username password list all users: rabbitmqctl list_users delete user: rabbitmqctl delete_user username clear user right: rabbitmqctl clear_permissions-p vhostpath Username lists user permissions: rabbitmqctl list_user_permissions username modify password: rabbitmqctl change_password username newpassword set user permissions: rabbitmqctl set_permissions-p vhostpath username ". *" Cluster management composition cluster command: rabbitmqctl join_cluster [--ram] View cluster status: rabbitmqctl cluster_status modify the storage form of cluster nodes: rabbitmqctl change_cluster_node_type disc | ram removal node: rabbitmqctl forget_ Cluster_node [--offline] modify node name: rabbitmqctl rename_cluster_node oldnode1 newnode1 [oldnode2 newnode2] remove all data: rabbitmqctl reset (to be used after rabbitmqctl stop_app)
