grails - Rabbitmq:手动创建的用户无法正常工作

Question

我刚开始使用 Rabbitmq ，并且尝试将其与grails一起使用。我在grails中成功设置了Rabbitmq。当我使用用户名=“guest”和密码=“guest”创建连接时，它可以正常工作，但是当我尝试使用手动创建的用户时，会引发一些错误，如下所示:

我向该用户提供了所有权限，并将管理员添加为标签。请帮我。

实际上我遇到了同样的问题，您只需先检查或按照以下步骤操作即可:

1)使用命令创建用户sudo rabbitmqctl add_user username password
2)现在为您的用户名设置标签为adminsudo rabbitmqctl set_user_tags username administrator
3)现在通过创建一个新的virtualHostsudo rabbitmqctl add_vhost test
4)之后，给予完全许可sudo rabbitmqctl set_permissions -p test username ".*" ".*" ".*"
5)现在终于在您的配置文件中定义

connection host: "Ip for your server", username: "admin", password: "password" , virtualHost: "test"

现在再次运行您的代码，它将成功运行。
