Setting default CHARSET and DB Engine

Question

I recently updated my server's database system from MySQL to MariaDB. After update, everything works well.

But, when I went to phpMyAdmin, the default charset and types are changed:

At the end of this image, the default type was set to 'InnoDB' and charset was set to 'latin1_swedish_ci'. They were 'MyISAM' and 'utf8_general_ci' before. How can I revert my character set and type settings back, and how can I customize settings when I make new database?

When I looked at /etc/my.cnf and /etc/my.cnf.rpmnew, I couldn't find any settings related to DB type/charset.
