    2Patchlog: This software works with classic master-master schemes where one of the master is active (handles writes and, sometimes, reads) and other is passive (receives updates via replication and could handle reads).

    For MySQL 5.0.2 or above

    In the my.cnf file on server1 add:
    auto_increment_increment=2
    auto_increment_offset=1

    In the my.cnf file on server2 add:
    auto_increment_increment=2
    auto_increment_offset=2

    This will make the auto-increment on server1 go, 1,3,5,7,9,etc... and on server2 go, 2,4,6,8,etc... thereby preventing collisions.
