450 PLEASE REMEMBER TO SET A PASSWORD FOR THE MySQL USERS!
451 This is done (after starting database) with:
453 /usr/bin/mysqladmin -u mysql -S $MYSQL_SOCKET password 'password'
454 /usr/bin/mysqladmin -h $hostname -u mysql -S $MYSQL_SOCKET password 'password'
455 /usr/bin/mysqladmin -u mysql_logrotate -S $MYSQL_SOCKET password 'password'
457 NOTE: mysql_logrotate password should be placed to $MYSQL_CONFIG in
458 mysqladmin section. See the manual for more instructions.
460 IMPORTANT: The configuration file is mysqld.conf in MYSQ_DB_CLUSTERS directories.
466 Installation of grant tables FAILED!
468 Examine the logs in $MYSQL_DATA_DIR for more information. You can
469 also try to start the mysqld demon with:
471 /usr/sbin/mysqld --skip-grant &
473 You can use the command line tool /usr/bin/mysql to connect to the mysql
474 database and look at the grant tables:
476 shell> /usr/bin/mysql -u mysql mysql
479 Try 'mysqld --help' if you have problems with paths. Setting on
480 logging in /etc/mysqld.conf gives you a log in /var/log/mysql/log that
481 may be helpful. The latest information about MySQL is available on the
482 web at http://www.mysql.com/.
484 Please check PLD ftp site for newer versions of this package.
486 Please consult the MySQL manual section: 'Problems running
487 mysql_install_db', and the manual section that describes problems on
488 your OS. Another information source is the MySQL email archive.
489 Please check all of the above before mailing us! And if you do mail
490 us, you MUST use the /usr/bin/mysqlbug script!
