setup permission for mysqldump

1. Create ~/.my.cnf, add these lines:
   

   [mysqldump]

   password=student
   chmod 0600 ~/.my.cnf

2. Inside phpmyadmin, set 'Select' and 'LOCK TABLES' permission to database 'drupal' for 'student' as the following image:
   
   
   
3. Then, dump drupal with the command without username and password:
   

    mysqldump drupal > kpchiao9600k_drupal.sql

   or
   

    mysqldump -B drupal > kpchiao9600k_drupal.sql

   CREATE DATABASE /*!32312 IF NOT EXISTS*/ `drupal` /*!40100 DEFAULT CHARACTER SET latin1 */;
   
   USE `drupal`;
