For 'mysql' user (ALL privileges, DB admin):

NOTE: mysql_sysadmin password should be placed to $MYSQL_CONFIG in

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.

	561	Examine the logs in /var/log/mysql for more information. You can
	562	also try to start the mysqld daemon with:
	563
	564	/usr/sbin/mysqld --skip-grant &
	565
	566	You can use the command line tool mysql to connect to the mysql
	567	database and look at the grant tables:
	568
	569	shell> mysql -u mysql mysql
	570	mysql> show tables
	571
	572	Try 'mysqld --help' if you have problems with paths. Setting on
	573	logging in $MYSQL_DATA_DIR/mysqld.conf gives you a log in /var/log/mysql/query.log that
	574	may be helpful. The latest information about MySQL is available on the
	575	web at http://www.mysql.com/.
	576
	577	Please check PLD Linux ftp site for newer versions of this package.
	578
	579	Please consult the MySQL manual section: 'Problems running
	580	mysql_install_db', and the manual section that describes problems on
	581	your OS. Another information source is the MySQL email archive.
