PLEASE REMEMBER TO SET A PASSWORD FOR THE MySQL USERS!
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.

dc7a177f	483	You can use the command line tool mysql to connect to the mysql
e9ca44ab	484	database and look at the grant tables:
e9ca44ab	485
dc7a177f	486	shell> mysql -u mysql mysql
e9ca44ab	487	mysql> show tables
	488
	489	Try 'mysqld --help' if you have problems with paths. Setting on
4581ca2d	490	logging in $MYSQL_DATA_DIR/mysqld.conf gives you a log in /var/log/mysql/query.log that
e9ca44ab	491	may be helpful. The latest information about MySQL is available on the
78b16243	492	web at http://www.mysql.com/.

a3eb9e7b	494	Please check PLD Linux ftp site for newer versions of this package.
e9ca44ab	495
	496	Please consult the MySQL manual section: 'Problems running
	497	mysql_install_db', and the manual section that describes problems on
	498	your OS. Another information source is the MySQL email archive.
