我似乎有問題,讓Solr的運行起來,我跟着蒞臨指導Solr的RequestHandler初始化失敗
http://andres.jaimes.net/878/setup-lucene-solr-centos-tomcat/
一切順利,但現在我想從MySQL導入數據。要做到這一點,我在本指南
http://www.wheelsandcogs.co.uk/2011/01/13/solr-tomcat-mysql-ubuntu/
一直跟隨我的時候它添加到我的solrconfig.xml中
<requestHandler name="/dataimport" class="org.apache.solr.handler.dataimport.DataImportHandler">
<lst name="defaults">
<str name="config">data-config.xml</str>
</lst>
</requestHandler>
這是我的錯誤的錯誤出現。如果我刪除這個,solr運行良好,但我無法從mysql導入。

我正在運行Centos,因此使用第一個指南來啓動並運行。第二個指南是針對Ubuntu的,在開始安裝JDBC時有一個步驟,我不知道我是否做得對。我想知道這是否可能是問題的一部分。
的文件夾謝謝!它對我來說工作得很好。 – HCarrasko
