ACCESS_REFUSED - Login was refused using authentication mechanism AMQPLAIN

今天在做公司项目的时候，发现自己本地怎么也连不上rabbitmq,总是报下面这个错误：

Fatal error: Uncaught PhpAmqpLib\Exception\AMQPProtocolConnectionException: ACCESS_REFUSED - Login was refused using authentication mechanism AMQPLAIN. For details see the broker logfile. in /opt/pt-php-push/vendor/php-amqplib/php-amqplib/PhpAmqpLib/Connection/AbstractConnection.php:726

主要信息其实是：

Login was refused using authentication mechanism AMQPLAIN. For details see the broker logfile.

然后我打开mq的log看了下，里面有这样的信息：

2019-08-25 22:49:38.916 [error] <0.2761.0> Error on AMQP connection <0.2761.0> (192.168.1.105:57246 -> 192.168.1.105:5672, state: starting):
AMQPLAIN login refused: user 'guest' can only connect via localhost

意思是说guest这个用户只能通过localhost连接。

然后解决办法参考的是这篇文章：

https://ask.openstack.org/en/question/90260/amqplain-login-refused-user-guest-can-only-connect-via-localhost/?sort=latest

通过重新创建一个新用户，并进行授权，然后使用新用户连接，就成功了。

➜  ~ /usr/local/Cellar/rabbitmq/3.7.15/sbin/rabbitmqctl add_user qinjianbo qinjianbo

Stopping `rabbitmq`... (might take a while)
