#1286 - Unknown storage engine 'InnoDB'

Im update mysql 50 to percona server 55 from yum repo.
And get this error #1286 - Unknown storage engine ‘InnoDB’

And i view type of table in phpmyadmin

MyISAM MyISAM storage engine
MRG_MYISAM Collection of identical MyISAM tables
CSV CSV storage engine
BLACKHOLE /dev/null storage engine (anything you write to it disappears)
MEMORY Hash based, stored in memory, useful for temporary tables
