[Wylug-help] How to setup mysql??

[Emon]

Hi all

I am a newbie running Slackware 10.2 with KDE desktop

I am trying to setup mythtv, so I am also having to setup mysql.

I don't know anything about databases so I am kind of trying to 
(blindly) follow the instructions in the docs & the file 
/etc/rc.d/rc.mysqld to get mysql up & running...

My runlevel in /etc/inttab is 4 & this is what I see during startup

*********************
Starting mysqld daemon with databases from /var/lib/mysql
                  /usr/sbin/nmbd -D
Starting gpm:  /usr/sbin/gpm -m /dev/mouse -t imps2
Starting lirc daemon: lircd & lircmd... Done
Starting Guarddog...
STOPPING server from pid file /var/run/mysql/mysql.pid
060410 18:04:02  mysqld ended
Done
Starting LISa daemon...
Done
Starting up X11 session manager...

I am still getting the following error while trying to run mythtv

**********************
QSqlQuery::exec: database not open
QSqlQuery::exec: database not open
2006-04-10 18:18:34.505 DB Error (KickDatabase):

No error type from QSqlError?  Strange...

QMYSQL3: Unable to connect
Database error was:
Can't connect to local MySQL server through socket 
'/var/run/mysql/mysql.sock' (2)

So what is it that I am doing wrong??

Thanks

BTW I also encountered the following errors while running

mysql at magic-box:~$ mysql_install_db
