481 This is done (after starting database) with:

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