mysql-----------release版创建密码

            

                    前提是你用无密码的进入创建一个数据库，然后使用该数据库后

(设置所有ip访问)

use mysql;
GRANT ALL ON *.* TO root@'%' IDENTIFIED BY 'your password' WITH GRANT OPTION;

（设置本地访问）

use mysql;

grant all on *.* to 'root'@'localhost' IDENTIFIED BY 'your password' with grant option;

当然也可以 update user set password='your password' where user='root';
