483 This is done (after starting database) with:

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