update user set password = password ('xxxx') where user = "root";
grant all privileges on *.* to root@'%' identified by 'xxxx';
其它参数的例子：
grant select,insert,update,delete,create,drop on vtdc.employee to joe@10.163.225.87 identified by '123';
给来自10.163.225.87的用户joe分配可对数据库vtdc的employee表进行select,insert,update,delete,create,drop等操作的权限，并设定口令为123。
要重启一次MYSQL才能使本地用户密码生效：
/usr/local/mysql/support-files/mysql.server restart
