__Quick start__
To directly use the masterserver you will need a webserver with PHP >= 5 and access to a MySQL-database. Start by opening the folder web and navigating through server and include, open the config.ini. Enter you're preferences there, everything is documented.
IMPORTANT: Before you continue make sure this folder will be inaccessible through the web later by making sure a working .htaccess is present on an Apache server or there is a corresponding chmod on the whole include folder after uploading later on.
Open a connection to your MySQL-server directly or via a tool like phpMyAdmin and query the command listet below to create the table structure. You can change the default prefix without any problems, just don't forget to change it in your config file.
Now upload the contents of the web/ folder. Now you should be able to open the root and see the server frontend. Make sure again, that the /server/include folder can NOT be accessed via web, since it contains your MySQL-data.
The installation should now be complete and ready to use. You can see the server link on the frontend, just put it in your Clonk network settings and you're done!
__Database__
CREATE TABLE IF NOT EXISTS `c4ms_flood` (
`ip` char(32) NOT NULL,
`count` int(11) NOT NULL,
`time` char(20) NOT NULL,
PRIMARY KEY (`ip`)
) ENGINE=MyISAM DEFAULT CHARSET=latin1;
CREATE TABLE IF NOT EXISTS `c4ms_games` (
`id` int(11) NOT NULL AUTO_INCREMENT,
`ip` varchar(255) NOT NULL,
`csid` varchar(255) NOT NULL,
`data` text NOT NULL,
`start` varchar(255) NOT NULL,
`time` varchar(255) NOT NULL,
`valid` tinyint(4) NOT NULL,
PRIMARY KEY (`id`)
) ENGINE=MyISAM DEFAULT CHARSET=latin1 AUTO_INCREMENT=1 ;
