428 PLEASE REMEMBER TO SET A PASSWORD FOR THE MySQL USERS!
429 This is done (after starting database) with:
431 /usr/bin/mysqladmin -u mysql password 'password'
432 /usr/bin/mysqladmin -h $hostname -u mysql password 'password'
433 /usr/bin/mysqladmin -u mysql_logrotate password 'password'
435 NOTE: mysql_logrotate password should be placed to $MYSQL_CONFIG in
436 mysqladmin section. See the manual for more instructions.
438 NOTE: if you are using cluster ability of this package you need
439 to specify different socket for each cluster (see --socket option)
445 Installation of grant tables FAILED!
447 Examine the logs in $MYSQL_DATA_DIR for more information. You can
448 also try to start the mysqld demon with:
450 /usr/sbin/mysqld --skip-grant &
452 You can use the command line tool /usr/bin/mysql to connect to the mysql
453 database and look at the grant tables:
455 shell> /usr/bin/mysql -u mysql mysql
458 Try 'mysqld --help' if you have problems with paths. Setting on
459 logging in /etc/mysqld.conf gives you a log in /var/log/mysql/log that
460 may be helpful. The latest information about MySQL is available on the
461 web at http://www.mysql.com/.
463 Please check PLD ftp site for newer versions of this package.
465 Please consult the MySQL manual section: 'Problems running
466 mysql_install_db', and the manual section that describes problems on
467 your OS. Another information source is the MySQL email archive.
468 Please check all of the above before mailing us! And if you do mail
469 us, you MUST use the /usr/bin/mysqlbug script!
