One: mysql> set password for-> 'some_user' @ 'some_host' = Old_password ('newpwd'); this command is not entering set password for pressing Enter? 'Some_user' is your own new username? 'Some_host 'Write localhost?' Newpwd 'writes your own new password? Second: mysql> update mysql.user set password = Old_password (' newpwd ') -> where host =' some_host 'and user =' some_user '; mysql> flush privileges;
