Rabbitmq新增用户角色

首先，查看一下当前有哪些用户：

$ /usr/local/sbin/rabbitmqctl list_users
Listing users ...
patty    [administrator]
guest    [administrator]

然后，我们新增一个用户wgm并再次查看新增后的用户列表：

$ /usr/local/sbin/rabbitmqctl add_user wgm 123456

$ /usr/local/sbin/rabbitmqctl list_users
Listing users ...
patty    [administrator]
wgm    []
guest    [administrator]

由于此时还未对wgm授予角色， wgm的角色一栏结果还是[],现在，我们授予wgm administrator角色

$ /usr/local/sbin/rabbitmqctl set_user_tags wgm administrator
Setting tags for user "wgm" to [administrator] ...

$ /usr/local/sbin/rabbitmqctl list_users
Listing users ...
patty    [administrator]
wgm    [administrator]
guest    [administrator]

接下来，查看我们当前在哪个virtual host上，以及该virtual host上所有用户所拥有的权限：

$ /usr/local/sbin/rabbitmqctl list_vhosts
Listing vhosts ...
/

$ /usr/local/sbin/rabbitmqctl list_permissions -p /
Listing permissions in vhost "/" ...
guest    .*    .*    .*
patty    .*    .*    .*

可见当前vhost上有默认用户guest,以及之前通过rabbitmqadmin管理界面添加的用户patty, 他们拥有该vhost所有的配置、读写权限。此时并没有显示wgm，是因为我们还未对他进行赋权，当然，我们也可以单独查看一个用户的权限信息：

$ /usr/local/sbin/rabbitmqctl list_user_permissions wgm
Listing permissions for user "wgm" ...

现在，对wgm这个用户进行授权，赋予其在"/"这个vhost上所有的配置、读写权限。

$ /usr/local/sbin/rabbitmqctl set_permissions -p / wgm ".*" ".*" ".*" 
Setting permissions for user "wgm" in vhost "/" ...

$ /usr/local/sbin/rabbitmqctl list_user_permissions wgm
Listing permissions for user "wgm" ...
/    .*    .*    .*

set_permissions命令格式为：

set_permissions [-p vhost] {user} {conf} {write} {read}， conf对应配置权限， write写权限， read读权限

现在，再查看“/”这个vhost的权限信息，会发现多了一个“wgm”

$ /usr/local/sbin/rabbitmqctl list_permissions -p / 
Listing permissions in vhost "/" ...
guest    .*    .*    .*
wgm    .*    .*    .*
patty    .*    .*    .*

接下来，我们通过Python程序验证，使用用户wgm来发送消息信息，然后guest用户去接收消息。
