未捕获的ErrorException：stream_socket_client（）：SSL：握手超时

Question

我尝试从php连接到RabbitMQ。 这是我在遵循这些问题后的配置：https://www.rabbitmq.com/ssl.html

/etc/rabbitmq/rabbitmq.config

[
  {rabbit, [
     {password_hashing_module, rabbit_password_hashing_sha512},
     {ssl_listeners, [{"0.0.0.0", 5671}]},
     {ssl_options, [{cacertfile,"/var/www/rabbitmq/testca/cacert.pem"},
                    {certfile,"/var/www/rabbitmq/server/cert.pem"},
                    {keyfile,"/var/www/rabbitmq/server/key.pem"}
     ]}
   ]}
].

使用这个php lib：https://github.com/php-amqplib/php-amqplib

netstat -lpn | grep 5671
tcp        0      0 0.0.0.0:5671            0.0.0.0:*               LISTEN      10420/beam.smp  

Php测试脚本：

use PhpAmqpLib\Connection\AMQPSSLConnection;
use PhpAmqpLib\Message\AMQPMessage;
define('AMQP_DEBUG', true);
$ssl_options = array(
  'cafile' => '/var/www/rabbitmq/testca/cacert.pem',
  'certfile' => '/var/www/rabbitmq/client/cert.pem',
  'keyfile' => '/var/www/rabbitmq/client/key.pem',
  'allow_self_signed' => true,
  'verify_peer' => true
);
$connection = new AMQPSSLConnection(
  '192.168.1.10',
  5671,
  'user',
  'pass',
  '/',
  $ssl_options);
$channel = $connection->channel();

我收到此错误：

PHP Fatal error:  Uncaught ErrorException: stream_socket_client(): SSL: Handshake timed out in /var/www/vendor/php-amqplib/php-amqplib/PhpAmqpLib/Wire/IO/StreamIO.php:134

StreamIO.php第134行是＆＃34; $错误号，＆＃34;：

try {
            $this->sock = stream_socket_client(
                $remote,
                $errno,
                $errstr,
                $this->connection_timeout,
                STREAM_CLIENT_CONNECT,
                $this->context
            );
        } catch (\ErrorException $e) {
            restore_error_handler();
            throw $e;
        }

操作系统：Ubuntu 16.04

PHP：7.0.22

执行此脚本时，RabbitMQ日志为空。
