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