484 This is done (after starting database) with:

487 /usr/bin/mysqladmin -h $hostname -u mysql -S $MYSQL_SOCKET password 'password'
488 /usr/bin/mysqladmin -u mysql_logrotate -S $MYSQL_SOCKET password 'password'
490 NOTE: mysql_logrotate password should be placed to $MYSQL_CONFIG in
491 mysqladmin section. See the manual for more instructions.
493 IMPORTANT: The configuration file is mysqld.conf in MYSQ_DB_CLUSTERS directories.
499 Installation of grant tables FAILED!
501 Examine the logs in $MYSQL_DATA_DIR for more information. You can
502 also try to start the mysqld demon with:
504 /usr/sbin/mysqld --skip-grant &
506 You can use the command line tool /usr/bin/mysql to connect to the mysql
507 database and look at the grant tables:
509 shell> /usr/bin/mysql -u mysql mysql
512 Try 'mysqld --help' if you have problems with paths. Setting on
513 logging in /etc/mysqld.conf gives you a log in /var/log/mysql/log that
514 may be helpful. The latest information about MySQL is available on the
515 web at http://www.mysql.com/.
517 Please check PLD ftp site for newer versions of this package.
519 Please consult the MySQL manual section: 'Problems running
520 mysql_install_db', and the manual section that describes problems on
521 your OS. Another information source is the MySQL email archive.
522 Please check all of the above before mailing us! And if you do mail
523 us, you MUST use the /usr/bin/mysqlbug script!
