title: Solr Configuration
body: <p>I tried to installed Solr using:</p>
  
  <pre><code>java -jar start.jar
  </code></pre>
  
  <p>However I downloaded the source code and didn't compile it (Didn't pay attention). And the error was:</p>
  
  <pre><code>http://localhost:8983/solr/admin/
  
  HTTP ERROR: 404
  Problem accessing /solr/admin/. Reason:
  NOT_FOUND 
  </code></pre>
  
  <p>Then I downloaded the compiled version of solr but when trying to run the example configuration I'm getting exception: </p>
  
  <pre><code>java.net.BindException: Address already in use 
  </code></pre>
  
  <p>Is there a way to revert solr configuration and start from scratch? Looks like the configuration got messed up. I don't see anything related to it in the manual.</p>
  
  <p>Here is the error:</p>
