mysql5.5.3 and above modify default encoding after start failure

I. Background of the problem

After installing 5.6.21 MySQL, there is a coding problem.

Show variables like '%character% '; display character_set_database and character_set_server values are latin1;

By set character_set_server= ' UTF8 ', again the view is actually utf8, but there are still coding errors,

After restarting the MYSQLD service, review the value of the variable and revert to latin1.

Ii. process of Settlement

Edit the My.cnf file.

<!-- lang: shell -->[mysqld]default-character-set=utf8

Restart Mysqld. Cannot restart after shutdown, view error log ***.local.err file.
