[CentOS] mysql

I just installed CentOS 3.5.  Included in the install was mysql.  When 
trying to start it using: service mysqld start.  The system responds 
with mysqld not recpognized as a service.  When trying to use 
/usr/bin/mysql I receive this error: ERROR 2002: Can't connect to local 
MySQL server through socket '/var/lib/mysql/mysql.sock' (2).  A search 
of the system does not reveal mysql.sock. 

Anyone have any ideas?

Thanks for any assistance.
