我是 solr 的新手，遇到了一些问题，想知道是否有人可以帮助我。
我跟着这个：http ://crazorsharp.blogspot.com/2010/01/full-text-search-using-solr-lucene-and.html
我下载了：Apache Tomcat/8.0.0-RC5 和 Solr 版本 4.5.1 被下载
如果我尝试http://localhost:8983我会得到 Apache Tomcat 网页，但如果我尝试http://localhost:8983/solr我会收到此错误：
HTTP 状态 404 - /solr
类型状态报告
消息/solr
描述 请求的资源不可用。
Apache Tomcat/8.0.0-RC5
其他一些人报告了此错误，这些似乎已通过添加以下内容来修复它：
<env-entry>
<env-entry-name>solr/home</env-entry-name>
<env-entry-value>c:/solr</env-entry-value>
<env-entry-type>java.lang.String</env-entry-type>
</env-entry>
这对我不起作用:(
请问有什么想法吗？
顺便提一句：
In logs I'm getting these errors:
