hello drupal support team,

thanks for your reply.
i tried /etc/init.d/mysql start and it is ok for the database, however, after i reboot the pc and run /etc/init.d/mysql start as below, it doesn't work again. thanks for your help with this again.

root@quicksu-desktop:/var/www/sites/all/modules# /etc/init.d/mysql start

Rather than invoking init scripts through /etc/init.d, use the service(8)
utility, e.g. service mysql start

Since the script you are attempting to invoke has been converted to an

Upstart job, you may also use the start(8) utility, e.g. start mysql
start: Job is already running: mysql

root@quicksu-desktop:/var/www/sites/all/modules# mysql
ERROR 2002 (HY000): Can't connect to local MySQL server through socket '/var/run/mysqld/mysqld.sock' (2)
