It seems to be the Default-character-set=utf8 of this set of trouble ....

Later learned that because MySQL 5.5 modifies the character set settings parameter

Should be changed to:

Replace Default-character-set=utf8 with Character_set_server=utf8

We can solve this problem.

Try and replace Character_set_server=utf8.
