Title Body

I am trying to configure user permissions in RabbitMQ using rabbitmqctl . The RabbitMQ documentation http://www.rabbitmq.com/man/rabbitmqctl.1.man.html gives a basic example of setting configure, write, and read permissions: rabbitmqctl set_permissions -p /myvhost tonyg "^tonyg-.*" ".*" ".*" but does not give any more detailed examples. I have looked at several posts on this topic but have not found answers to my specific questions. First question: Is it necessary to grant permissions to both exchanges and queues to which a user can write, or just the exchanges? Similarly for reading, is it enough to specify the queues? The documentation just talks about granting access to "resources". Second question: The example above uses a caret to mark the beginning of the resource name. If I omit this, and just use "tonyg-.*", would that allow the specified text to appear anywhere in the resource name? Similarly, if I wanted to specify the entire resource name, must I bracket it with ^ and $, as in "^myqueue$"? Third question: Say I want to specify more than one pattern for a given permission. Can I just separate the patterns with commas, something like rabbitmqctl set_permissions -p /myvhost tonyg "^tonyg-.*,^test-.*" ".*" ".*" Is this the correct syntax for this? If not, what is? Fourth question: What is the required syntax for vhost names? The other examples on the cited man page do not use a leading slash, as in rabbitmqctl add_vhost test Are the vhost names in some way structured, or is the slash just another character in the name? Thanks for any suggestions!
