Have you run 'sh /script/mysql-convert --engine=innodb' before?.
If not, it's maybe something wrong with your innodb storage-engine of mysql.
If you found 'default-storage-engine=innodb' and 'skip-innodb', change it and then run your mysql.
Look like mysql51/mysql55 from IUS have a problem now. Many issues related to Kloxo-MR installing effect by mysql51/mysql55.
I didn't found any issue for mysql from Centos or MariaDB.
