无法加载solrconfig.xml

Question

我在我的drupal网站上使用Apache Solr。Tomcat6已经安装，我已经用模块安装目录中的新文件替换了schema.xml、solr-config.xml和protwords.txt文件。

当我运行localhost:8983时，我得到这个错误。

Log4j (org.slf4j.impl.Log4jLoggerFactory)

2533 [main] INFO  org.apache.solr.servlet.SolrDispatchFilter  – user.dir=/opt/solr-4.5.1/example

有谁能帮上忙吗？

谢谢

这可能与搜索API Solr模块提供的默认Solr配置文件有关。尝试从solrconfig.xml中删除以下几行：

<useCompoundFile>false</useCompoundFile>
<ramBufferSizeMB>32</ramBufferSizeMB>
<mergeFactor>10</mergeFactor>
