解决方法：
1,修改user表
mysql -u root -p
mysql>use mysql;
mysql>update user set host = ‘172.27.241.1‘ where user =‘root‘;
mysql>flush privileges;
2.指定授权
mysql -u root -p
mysql>use mysql;
mysql>GRANT ALL PRIVILEGES ON *.* TO ‘root‘@‘172.27.241.1‘ IDENTIFIED BY ‘mypassword‘ WITH GRANT OPTION;
mysql>flush privileges;
注意：
1.精准授权，即那个账号，哪台主机，需要哪种权限，必须写明，最好不要泛授权；
2.记着执行完每条命令要flush privileges;
