Solutions:

edit /etc/mysql/my.conf, add 3 lines in [mysqlid]section:

collation-server = utf8_general_ci
init-connect='SET NAMES utf8'
character-set-server = utf8

then login glance database in mysql, change table charset:

mysql> alter table migrate_version convert to character set 'utf8';

OK, that's ok!
