解决办法：
vim /etc/my.cnf，根据实际情况进行参数调整：
[mysqld]
max_allowed_packet = 1G
innodb_log_file_size = 30M
innodb_log_buffer_size = 512M
innodb_file_format='Barracuda'
alter table 'role' row_format=dynamic
修改之后，重启mysql服务。
mysql文档
https://dev.mysql.com/doc/relnotes/mysql/5.6/en/news-5-6-20.html
In MySQL 5.6.22, the redo log BLOB write limit is relaxed to 10% of the total redo log size (innodb_log_file_size * innodb_log_files_in_group).
