php - Rabbitmq - php amqp broken broken pipe 错误

Question

我正在处理一个巨大的 xml 文档(其中包含大约一百万个条目)，然后使用 rabbitmq 将格式化版本导入数据库。每次发布大约 200,000 个条目后，我都会收到一个 broken pipe 错误，并且 rabbitmq 无法从中恢复。

Notice Error: fwrite(): send of 2651 bytes failed with errno=11 Resource temporarily unavailable in [/var/www/ribbon/app/Console/Command/lib/php_amqplib/amqp.inc, line 439]

Notice Error: fwrite(): send of 33 bytes failed with errno=104 Connection reset by peer in [/var/www/ribbon/app/Console/Command/lib/php_amqplib/amqp.inc, line 439]

Notice Error: fwrite(): send of 19 bytes failed with errno=32 Broken pipe in [/var/www/ribbon/app/Console/Command/lib/php_amqplib/amqp.inc, line 439]

这随后会导致节点关闭错误，需要手动终止进程才能从中恢复。

这些是我的类方法:-

public function publishMessage($message) {
    if (!isset($this->conn)) {
        $this->_createNewConnectionAndChannel();
    }
    try {
        $this->ch->basic_publish(
            new AMQPMessage($message, array('content_type' => 'text/plain')), 
            $this->defaults['exchange']['name'], 
            $this->defaults['binding']['routing_key']
        );
    } catch (Exception $e) {
        echo "Caught exception : " . $e->getMessage();
        echo "Creating new connection.";
        $this->_createNewConnectionAndChannel();
        $this->publishMessage($message); // try again
    }
}

protected function _createNewConnectionAndChannel() {
    if (isset($this->conn)) {
        $this->conn->close();
    }

    if(isset($this->ch)) {
        $this->ch->close();
    }

    $this->conn = new AMQPConnection(
        $this->defaults['connection']['host'], 
        $this->defaults['connection']['port'], 
        $this->defaults['connection']['user'], 
        $this->defaults['connection']['pass']
    );
    $this->ch = $this->conn->channel();
    $this->ch->access_request($this->defaults['channel']['vhost'], false, false, true, true);
    $this->ch->basic_qos(0 , 20 , 0); // fair dispatching

    $this->ch->queue_declare(
        $this->defaults['queue']['name'],
        $this->defaults['queue']['passive'],
        $this->defaults['queue']['durable'],
        $this->defaults['queue']['exclusive'],
        $this->defaults['queue']['auto_delete']
    );

    $this->ch->exchange_declare(
        $this->defaults['exchange']['name'],
        $this->defaults['exchange']['type'],
        $this->defaults['exchange']['passive'],
        $this->defaults['exchange']['durable'],
        $this->defaults['exchange']['auto_delete']
    );

    $this->ch->queue_bind(
        $this->defaults['queue']['name'],
        $this->defaults['exchange']['name'],
        $this->defaults['binding']['routing_key']
    );
}

我们将不胜感激。

确保您已在 Rabbit MQ 上为您的用户添加了虚拟主机访问权限。我创建了新用户并忘记了为默认使用的“/”主机设置访问权限。

您可以通过管理面板 yourhost:15672 > Admin > 点击用户 > 寻找“设置权限”。

附言我假设您的 RabbitMQ 服务正在运行，用户存在且密码正确。
