Question

我正在使用Nutch和Solr索引文件共享。

我首先发出：bin / nutch抓取网址

这给了我：

LinkDb: finished at 2011-08-04 19:14:26, elapsed: 00:00:01
crawl finished: crawl-20110804191414

然后我：bin / nutch solrindex http://localhost:8983/solr/ crawl-20110804191414 / crawldb crawl-20110804191414 / linkdb crawl-20110804191414 / segments / *

这给了我：

SolrIndexer: starting at 2011-08-04 19:17:07
SolrIndexer: finished at 2011-08-04 19:17:08, elapsed: 00:00:01

当我在solr上执行：查询时，我得到：

<response>
     <lst name="responseHeader">
          <int name="status">0</int>
          <int name="QTime">2</int>
          <lst name="params">
               <str name="indent">on</str>
               <str name="start">0</str>
               <str name="q">*:*</str>
               <str name="version">2.2</str>
               <str name="rows">10</str>
          </lst>
     </lst>
     <result name="response" numFound="0" start="0"/>
</response>

：（

请注意，当我尝试使用protocol-http来抓取网站时，这种方式正常，但是当我使用协议文件来抓取文件系统时，这种方式无效。

--- --- EDIT 今天再次尝试此操作后，我注意到名称中带有空格的文件导致404错误。这是我正在索引的共享上的很多文件。但是，thumbs.db文件正好。这告诉我问题不是我想的那样。

Answer 1

今天我花了很多时间来回顾你的步伐。我最终在/opt/nutch/src/java/org/apache/nutch/indexer/IndexerMapReduce.java中使用了printf调试，它向我展示了我尝试索引的每个URL出现两次，一次以file：//开头/ var / www / Engineering /，正如我最初指定的那样，一旦从文件开始：/ u / u60 / Engineering /。在这个系统上，/ var / www / Engineering是/ u / u60 / Engineering的符号链接。此外，/ var / www / Engineering URL被拒绝，因为未提供parseText字段，并且因为未提供fetchDatum字段而拒绝了/ u / u60 / Engineering URL。在/ u / u60 / Engineering表单中指定原始URL解决了我的问题。希望在这种情况下有助于下一次闷烧。

Answer 2

这是因为solr没有获取索引数据。好像你没有正确执行以前的命令。重新启动整个过程，然后尝试最后一个命令。从此处复制命令：https://wiki.apache.org/nutch/NutchTutorial或在youtube上引用我的视频 - https://www.youtube.com/watch?v=aEap3B3M-PU&t=449s

在nutch solrindex命令之后Solr索引为空
