RabbitMQ 启动报错 Failed to check/redeclare auto-delete queue(s). access to vhost ‘/’ refused for user ‘rabbit’
今天项目在新的服务器上启动，所有的配置文件没变，安装完rabbitmq配置好以后，启动服务
服务器配置都是一样的，网络也没问题
结果发现报错了 Failed to check/redeclare auto-delete queue(s). 错误如下：

第一想法 是不是rabbitMQ队列有问题，提示的是检查删除队列除了问题
-
第二想法 往下看报错原因 reply-code=530, reply-text=NOT_ALLOWED - access to vhost ‘/’ refused for user ‘rabbit’
仔细看错误可以看到如下：
Caused by: com.rabbitmq.client.ShutdownSignalException: connection error; protocol method: #method<connection.close>
(reply-code=530, reply-text=NOT_ALLOWED - access to vhost ‘/’ refused for user ‘rabbit_root’, class-id=10, method-id=40)恍然大悟，这里应该是缺少了一些配置，配置vhost针对用户rabbit的相关权限配置
然后 查了一下，发现 RabbitMQ需要针对用户设置vhost权限
vhost给权限到用户 rabbitmqctl set_permissions -p "/" username ".*" ".*" ".*" 给xiao ming分配test名的vhost权限 rabbitmqctl set_permissions -p "test" xiaoming ".*" ".*" ".*"重启服务，就可以了，然后发现 RabbitMQ正常运行
