title: make_sock: could not bind to address 0.0.0.0:8888
body: <p>This error appears when i tried to restart apache</p>
  
  <pre><code>(98)Address already in use: make_sock: could not bind to address 0.0.0.0:8888 
  no listening sockets available, shutting down
  </code></pre>
  
  <p>I had a map server running at port 8888. I tried to do a Redirect so that a direct access of the map server from remote is redirected. The sites-available/domain_name file is</p>
  
  <pre><code>&lt;VirtualHost *:80&gt;
          ServerName domain_name
          ...
  &lt;/VirtualHost&gt;
  
  Listen *:8888 http
  &lt;VirtualHost *:8888&gt;
      ServerName domain_name
      Redirect permanent / http://domain_name/
      ...
      &lt;/VirtualHost&gt;
  </code></pre>
  
  <p>Is there a way to avoid this error and restart the apache server. The map server and apache running on same machine.</p>
  
  <p>Thanks in advance.</p>
