RabbitMQ set_permissions syntax noob
I've seen other posts on stackoverflow related in some ways to the ridiculous question I'm about to ask but none of them dumbed it down enough for me to get what I was looking for..
I've installed rabbitmq and it's running.
I've successfully add_user as well as add_vhost. But in the next step of the documentation it says to set_permissions and I'm failing.
I get Error: could not recognise command when I enter the following:
$ sudo rabbitmqctl set_permissions -p myvhost myuser ".*" ".*" ".*"
(this is copy and pasted verbatim from the documentation so it seems a bit ridiculous that it doesn't work.. And 'recognise' being misspelled in the error msg isn't helping)
My question is what does ".*" ".*" ".*" mean/stand for?
Answer
From the documentation
set_permissions [-p vhostpath] {user} {conf} {write} {read}
vhostpath - The name of the virtual host to which to grant the user access, defaulting to /.
user - The name of the user to grant access to the specified virtual host.
conf - A regular expression matching resource names for which the user is granted configure permissions.
write - A regular expression matching resource names for which the user is granted write permissions.
read - A regular expression matching resource names for which the user is granted read permissions.
To answer your question specifically, ".*" ".*" ".*" is a set of three regular expressions (applying to configure, write, and read) which will match all the permissions available (. will match any character, * will match any number of the preceding character)
