Can't connect to RabbitMQ in PHP

Question

PHP

The essence of the problem: when connecting to the Rabbit server, the script throws out an error:
php: symbol lookup error: /usr/local/lib/php/extensions/no-debug-non-zts-20090626/amqp.so: undefined symbol: amqp_open_socket

The library file is present /usr/local/lib/php/extensions/no-debug-non-zts-20090626/amqp.so. The librabbitmq library is installed on the system.

Code that triggers the error:

    try
    {
      $Connection = new AMQPConnection();
      $Connection->setLogin('login');
      $Connection->setPassword('password');
      $Connection->setVhost('host');
      $Connection->setHost('localhost');
      $Connection->setPort(5672);
      $Connection->connect();
    }
    catch (\Exception $e)
    {
      echo 'Ошибка: ' . $e->getMessage();
    }

Searching for the corresponding function in the library binary yields:

$ nm -D /usr/local/lib/php/extensions/no-debug-non-zts-20090626/amqp.so | fgrep amqp_open_socket
                 U amqp_open_socket

The Rabbit server itself is running on port 5672:

$ sudo netstat -anlp | grep 5672
tcp        0      0 127.0.0.1:5672          0.0.0.0:*               LISTEN      16772/beam.smp

The amqp extension (for working with the Rabbit server in php) is installed via PECL:

$ php -c /usr/local/var/run/php.ini -m

Software versions:

Who can tell me what could be the solutions to the problem?

Answer 1

I also had some problems with RabbitMQ, they solved it by installing this library github.com/alanxz/rabbitmq-c instead of librabbitmq, which is in the ubunta repository. And it seems that you need to rebuild / reinstall the PHP extension.
