[ubuntu] unable to connect to mysql

Hi,

I am sorry for posting a popular question, but no available solution could help me.

mysql -uroot -p
Enter password:
ERROR 2002 (HY000): Can't connect to local MySQL server through socket '/var/run/mysqld/mysqld.sock' (2)

I did:
me@System / $ ps -e|grep mysqld
5354 pts/0 00:00:00 mysqld_safe
5713 pts/0 00:00:07 mysqld

I even can see that phpmyadmin is working.
Kindly suggest me some solution.
