PLEASE REMEMBER TO SET A PASSWORD FOR THE MySQL USERS!
This is done (after starting database; press enter when asked for password) with:

/usr/bin/mysqladmin -u mysql -p -S $MYSQL_SOCKET password 'password'
/usr/bin/mysqladmin -h $hostname -u mysql -p -S $MYSQL_SOCKET password 'password'
/usr/bin/mysqladmin -u mysql_logrotate -p -S $MYSQL_SOCKET password 'password'

NOTE: mysql_logrotate password should be placed to $MYSQL_CONFIG in
mysqladmin section. See the manual for more instructions.

Installation of grant tables FAILED!

Examine the logs in $MYSQL_DATA_DIR for more information.  You can
also try to start the mysqld demon with:

/usr/sbin/mysqld --skip-grant &

You can use the command line tool /usr/bin/mysql to connect to the mysql
database and look at the grant tables:

shell> /usr/bin/mysql -u mysql mysql
mysql> show tables

Try 'mysqld --help' if you have problems with paths. Setting on
logging in /etc/mysqld.conf gives you a log in /var/log/mysql/log that
may be helpful. The latest information about MySQL is available on the
web at http://www.mysql.com/.

Please check PLD Linux ftp site for newer versions of this package.

Please consult the MySQL manual section: 'Problems running
mysql_install_db', and the manual section that describes problems on
your OS.  Another information source is the MySQL email archive.
Please check all of the above before mailing us!  And if you do mail
us, you MUST use the /usr/bin/mysqlbug script!
