怎麼修改linux上mysql的root密碼?

# /etc/init.d/mysql stop

# mysqld_safe --user=mysql --skip-grant-tables --skip-networking &

# mysql -u root

mysql> use mysql

mysql> update user set password=password("newpassword") where user=‘root‘;

mysql> flush privileges;

mysql> quit

# /etc/init.d/mysql restart

# mysql -uroot -p

enter password: <輸入新設的密碼newpassword>

mysql>
