Rabbitmq用户名密码

1、有个默认的用户名密码guest，但是这个只能通过本地连接，如果在java的rabbitmq连接，会报以下错误：Caused by: com.rabbitmq.client.AuthenticationFailureException: ACCESS_REFUSED - Login was refused using authentication mechanism PLAIN. For details see the broker logfile.
        at com.rabbitmq.client.impl.AMQConnection.start(AMQConnection.java:385)

2、添加用户以及授权

添加用户：rabbitmqctl add_user username password

为该用户设置权限所有权限：rabbitmqctl set_permissions -p / username".*" ".*" ".*"

设置该用户为管理员角色：rabbitmqctl set_user_tags username administrator

3、查看所有用户：rabbitmqctl list_users

4、配置文件 rabbitmq.config
