Rabbitmq 访问控制

virtual host：
首次开启或者使用新数据库时，rabbitmq 会自动创建
1. a virtual host named /
2. a user named guest with a default password of guest, granted full access to the / virtual host.
推荐删除 guest 帐号，或者修改帐号密码。

Access control

When an AMQP client establishes a connection to an AMQP server, it specifies a virtual host within which it intends to operate. A first level of access control is enforced at this point, with the server checking whether the user has any permissions to access the virtual hosts, and rejecting the connection attempt otherwise.

Resources, i.e. exchanges and queues, are named entities inside a particular virtual host; the same name denotes a different resource in each virtual host. A second level of access control is enforced when certain operations are performed on resources.
