This is done, after starting database, in the order shown,
with:

For 'mysql_sysadmin' (RELOAD and SHUTDOWN privileges):
echo "update mysql.user set password=password('newpassword') where user='mysql_sysadmin'; FLUSH PRIVILEGES;" | mysql -u mysql -S $MYSQL_SOCKET

For 'mysql' user (ALL privileges, DB admin):
echo "update mysql.user set password=password('newpassword') where user='mysql'; FLUSH PRIVILEGES;" | mysql -u mysql -S $MYSQL_SOCKET

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

Installation of grant tables FAILED!

The initialization SQL script was preserved at $MYSQL_DATA_DIR/mysql-init.sql

Examine the logs in /var/log/mysql for more information.  You can
also try to start the mysqld daemon with:

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

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

shell> mysql -u mysql mysql
mysql> show tables

Try 'mysqld --help' if you have problems with paths. Setting on
logging in $MYSQL_DATA_DIR/mysqld.conf gives you a log in /var/log/mysql/query.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.
