486 This is done (after starting database) with:

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