Can't connect to RabbitMQ on Amazon MQ - php

Question

I created an Amazon MQ broker:
Select broker engine: RabbitMQ 3.8.6
Single-instance broker
Network and security: Public access
VPC and subnets: Use the default VPC and subnet(s)
I have tried two libraries: from RabbitMQ manual and Enqueue\AmqpExt
Either of them cannot connect to Amazon (with docker container all works fine. But I want to try AMAZON MQ.
I used code below:
use Enqueue\AmqpExt\AmqpConnectionFactory;
use PhpAmqpLib\Connection\AMQPSSLConnection;
$connectionFactory = new AmqpConnectionFactory([
'host' => 'b-da219bXXXXXXXXXXXX86a.mq.us-east-1.amazonaws.com',
'port' => 5671,
'vhost' => '/',
'user' => 'xxxx',
'pass' => 'xxxx', // I can login with this to rabbit admin panel
'persisted' => false,
'ssl_on' => false,
'ssl_verify' => false,
]);
$c = $connectionFactory->createContext();
$queue = $c->createQueue('emails');
$c->declareQueue($queue);
Result:
Library error: connection closed unexpectedly - Potential login failure.
With 'ssl_on' => true the same error.
I don't know can it be happen because I didn't provide ssl cert to amazon.
If so, how to fix it?

Answer 1

I've had success with php-amqplib, and I am actually not using the newest version (I am on v2.12.3). I can connect using this:
$connection = new AMQPSSLConnection($host, $port, $user, $pass, $vhost, ['verify_peer_name' => false], [], 'ssl');
I found that I had to set 'verify_peer_name' => false, or else I just got a unable to connect to ssl://localhost:5671 (Unknown error) error, but I was also port-forwarding through localhost.

Amazon MQ broker (RabbitMQ specifically) is using SSL by default (you can notice that connection string starts with amqps, not amqp
In your case, you should set to true ssl_on and ssl_verify options

Answered by #Eugene K in a sub-comment:
You need to add the DSN to the SSLOptions array, and you need to use a AMQPSSLConnection instead of an AMQPStreamConnection
$this->connection = new AMQPSSLConnection(
'myhost.mq.eu-west-1.amazonaws.com',
'5671',
'username',
'xxx',
'/',
[
'dsn' => 'amqps:'
]
);

I see you installed amqp-ext and using it's ConnectionFactory
use Enqueue\AmqpExt\AmqpConnectionFactory; but
If you are using php-enqueue and want to connect to AWS AMQ RabbitMQ you should install and use enqueue/amqp-lib instead of enqueue/amqp-ext
and connection details
use Enqueue\AmqpLib\AmqpConnectionFactory;
new AmqpConnectionFactory([
'host' => env('RABBITMQ_HOST'),
'port' => env('RABBITMQ_PORT', 5672),
'vhost' => env('RABBITMQ_DEFAULT_VHOST'),
'user' => env('RABBITMQ_USERNAME'),
'pass' => env('RABBITMQ_PASSWORD'),
'persisted' => false,
'ssl_on' => true,
'ssl_verify' => true,
]);
