The MySQL homepage says: 2. Free use for those who never copy, modify or distribute As long as you never distribute (internally or externally) the MySQL Software in any way, you are free to use it for powering your application, irrespective of whether your application is under GPL or other OSI approved license or not.
More specifically: Modifying - You are allowed to modify MySQL Software source code any way you like. If you distribute the modified version, all changes, all interface code and all code that connects directly or indirectly to the interface code fall under GPL. Copying - You are allowed to copy MySQL binaries and source code, but when you do so, the copies will fall under the GPL license. What does internal distribution mean? Is it another thing than copying? Consider this example: A company has 2 database servers and want to install MySQL on both servers. Is MySQL free for the first server, but require a license for the second server? Or are MySQL free for both servers? -- MySQL General Mailing List For list archives: http://lists.mysql.com/mysql To unsubscribe: http://lists.mysql.com/[EMAIL PROTECTED]
