RabbitMQ 常见错误汇总_user can only log in via localhost

报错现象1

rabbitMQ登录报错user can only log in via localhost

RabbitMQ默认只有一个guest帐号，guest帐号只能在RabbitMQ安装服务器上登录，在其它服务器用guest登录提示User can only log in via localhost。

解决办法1：

进入容器admin

这个情况的最佳解决办法是添加一个新的帐号

容器模式： sudo docker exec -it rabbitmq-server bash

#第一步：添加 admin 用户并设置密码
rabbitmqctl add_user admin 123456
#第二步：添加 admin 用户为administrator角色
rabbitmqctl set_user_tags admin administrator
#第三步：设置 admin 用户的权限，指定允许访问的vhost以及write/read
rabbitmqctl set_permissions -p "/" admin ".*" ".*" ".*"
#第四步：查看vhost（/）允许哪些用户访问
rabbitmqctl list_permissions -p /
#第五步：查看用户列表
rabbitmqctl list_users
#第六步：配置允许远程访问的用户，rabbitmq的guest用户默认不允许远程主机访问。
