RabbitMq 管理後臺使用方式：
發送消息：需要設置發送屬性：content_type=text/plain
payload裏面填寫數值。
rabbitMq新增用戶：
創建用戶
rabbitmqctl add_user {用戶名} {密碼}
// 設置權限
rabbitmqctl set_user_tags {用戶名} {權限}
例：創建一個超級用戶
rabbitmqctl add_user admin1 admin1
rabbitmqctl set_user_tags admin1 administrator
查看用戶列表
rabbitmqctl list_users
爲用戶賦權
// 使用戶user1具有vhost1這個virtual host中所有資源的配置、寫、讀權限以便管理其中的資源
rabbitmqctl set_permissions -p vhost1 user1 '.*' '.*' '.*'
// 查看權限
rabbitmqctl list_user_permissions user1
rabbitmqctl list_permissions -p vhost1
// 清除權限
rabbitmqctl clear_permissions [-p VHostPath] User
刪除用戶
rabbitmqctl delete_user Username
修改用戶的密碼
rabbitmqctl change_password Username Newpassword

原因：admin用戶沒有訪問權限"/"
問題解決：
rabbitmqctl set_permissions -p / admin '.*' '.*' '.*' #爲admin用戶分配讀、寫、配置權限；
