我试图安装使用Solr Nutch的关于网络爬虫的Apache Solr的，我下面一个YouTube教程https://www.youtube.com/watch?v=Qs-18hRRpNUHTTP状态500 - solr配置中的严重错误。在solr.xml
这是我的路C:\Program Files\Apache Software Foundation\Tomcat 6.0\webapps\solr\WEB-INF，当我安装了solr.xml文件如下。
下面是在Windows 10中安装Solr Apache与Tomcat的错误不知道如何将Solr 6与Solr Nutch集成，因此不得不退回到旧的Solr。下面是错误
**HTTP Status 500 - Severe errors in solr configuration.
Check your log files for more detailed information on what may be wrong.
If you want solr to continue after configuration errors, change:
<abortOnConfigurationError>false</abortOnConfigurationError> in solr.xml

<!-- If you are wiring Solr into a larger web application which controls
the web context root, you will probably want to mount Solr under
a path prefix (app.war with /app/solr mounted into it, for example).
You will need to put this prefix in front of the SolrDispatchFilter
url-pattern mapping too (/solr/*), and also on any paths for
legacy Solr servlet mappings you may be using.
For the admin JSP's to work properly in a path-prefixed configuration,
the admin folder containing the JSPs needs to be under the app context root
named to match the path-prefix. For example:
.war
xxx
admin
stats.jsp

NOTE: When using multicore, /admin JSP URLs with a core specified
such as /solr/coreName/admin/stats.jsp get forwarded by a
RequestDispatcher to /solr/admin/stats.jsp with the specified core
put into request scope keyed as "org.apache.solr.SolrCore".
It is unnecessary, and potentially problematic, to have the SolrDispatchFilter
configured to also filter on forwards. Do not configure
this dispatcher as <dispatcher>FORWARD</dispatcher>.
