Logstash启动配置文件 启动成功后立即被关闭 elasticsearch会显示 远程主机强迫关闭连接

The stdin plugin is now waiting for input:

以上是logstash启动配置文件后 报错信息。。我的配置文件如下：

input{

    stdin{}

}

output{

    elasticsearch{

        hosts => "192.168.0.100:9200"

    user => "elastic"

    password => "changeme"

    index => "megacorp"

     }

   stdout{codec => rubydebug}

}
