csv - 使用logstash将csv文件传输到服务器

Question

我目前正在学习使用大数据，
客户端:Windows 10
服务器端:CentOS7
elasticsearch，logstash和kibana已安装在服务器端，
作为客户端，我可以通过http://10.64.2.246:5601/访问kibana，一切都很酷。现在，我想学习如何将数据从我的PC传输到服务器端的elasticsearch。我已经在客户端下载了logstash。

我已经用2列从kaggle准备了数据。
我做了我的conf文件

conf文件

input   {
    file    {
        path => "C:\Users\Charles\Desktop\DATA"
        start_position => "beginning"
        sincedb_path=>"/dev/null"
    }
}
filter  {
    csv     {
        separator=>","
        columns=>["Date","Price"]
    }
    mutate {convert =>["Price","float"]}
}
output{
    elasticsearch{
        host => "10.64.2.246"
        index=>"oil"
        document_type=>"minyaks"
    }
    stdout{}
}

这是我执行在客户端执行的conf文件的代码。
bin/logstash -f /Users/Charles/Desktop/DATA/logstash_oil.conf
这是显示的错误

需要有人向我解释。我遵循youtube上的说明，但讲师是在本地进行的。

谢谢。

Answer 1

问题在这条线上:

[2019-11-07T20:33:12,917][ERROR][logstash.outputs.elasticsearch] Unknown setting 'host' for elasticsearch

所以你需要改变

    host => "10.64.2.246"

至

    hosts => "10.64.2.246"

另外，由于您似乎正在使用ES 7.4.2，因此可以将以下行删除为document/mapping types are deprecated

document_type=>"minyaks"
