Please modify 'tileserver.php' file and replace the '<?php echo $baseUrl ?>' in the $config variable with '<?php echo selfUrl(); ?>' (with slash in the end) or other correct address to your server. Multiple CNAME can be used for better performance - more in <a href="readme.md">readme.txt</a>.

Ready to go - just upload some maps into directory: <?php echo getcwd(); ?>/ on this server.
|

</p>
|

<p>
|
||||
Note: The maps can be a directory with tiles in XYZ format with metadata.json file.<br/>
|
||||
You can easily convert existing geodata (GeoTIFF, ECW, MrSID, etc) to this tile structure with <a href="http://www.maptiler.com">MapTiler Cluster</a> or open-source projects such as <a href="http://www.klokan.cz/projects/gdal2tiles/">GDAL2Tiles</a> or <a href="http://www.maptiler.org/">MapTiler</a> or simply upload any maps in MBTiles format made by <a href="http://www.tilemill.com/">TileMill</a>. Helpful is also the <a href="https://github.com/mapbox/mbutil">mbutil</a> tool. Serving directly from .mbtiles files is supported, but with decreased performance.
