.15 was the older library version. For 11.2 you need a python-mysql that uses the .16 API. Or perhaps a different module. Did you perhaps get it from outside the repo? Sorry I can’t explain it if python-mysql also came from the openSUSE official repo as I don’t have it installed.
As far as I see mysql config is /etc/my.cnf on 11.2. I installed it from the repos and test seems to work. And as ken_yap mention it 16. Try installing mysql-client trhough YaST if it is not selected as dependency.
