Logstash 无法连接到rabbitmq

Question

我正在尝试设置 logstash 配置以将行从文件推送到 rabbitmq。我在本地机器上安装了 logstash 2.1.1 和 rabbit 3.6.0 来测试它。输出配置为：

output {
    rabbitmq {
            exchange => "test_exchange"
            key => "test"
            exchange_type => "direct"
            host => "127.0.0.1"
            port => "15672"
            user => "logstash"
            password => "logstashpassword"
        }
}

但是当我现在启动 logstash 时，它无法启动并出现以下错误（输出仅在 logstash 在调试模式下启动时显示）：

Worker threads expected: 4, worker threads started: 4 {:level=>:info, :file=>"logstash/pipeline.rb", :line=>"186", :method=>"start_filters"}
Connecting to RabbitMQ. Settings: {:vhost=>"/", :host=>"127.0.0.1", :port=>15672, :user=>"logstash", :automatic_recovery=>true, :pass=>"logstashpassword", :timeout=>0, :heartbeat=>0} {:level=>:debug, :file=>"logstash/plugin_mixins/rabbitmq_connection.rb", :line=>"135", :method=>"connect"}
The error reported is:

然后logstash“崩溃”即停止。有谁知道这是否与 logstash 的配置有关，还是 rabbitMQ 设置中的问题？

提前致谢。 丹尼尔

发现我的错误是 rabbitMQ 的端口必须是 5672 而不是 15672。
