552 | The initialization SQL script was preserved at $MYSQL_DATA_DIR/mysql-init.sql | |

554 | Examine the logs in /var/log/mysql for more information. You can | |
555 | also try to start the mysqld daemon with: | |
556 | ||
557 | /usr/sbin/mysqld --skip-grant & | |
558 | ||
559 | You can use the command line tool mysql to connect to the mysql | |
560 | database and look at the grant tables: | |
561 | ||
562 | shell> mysql -u mysql mysql | |
563 | mysql> show tables | |
564 | ||
565 | Try 'mysqld --help' if you have problems with paths. Setting on | |
566 | logging in $MYSQL_DATA_DIR/mysqld.conf gives you a log in /var/log/mysql/query.log that | |
567 | may be helpful. The latest information about MySQL is available on the | |
568 | web at http://www.mysql.com/. | |
569 | ||
570 | Please check PLD Linux ftp site for newer versions of this package. | |
571 | ||
572 | Please consult the MySQL manual section: 'Problems running | |
573 | mysql_install_db', and the manual section that describes problems on | |
574 | your OS. Another information source is the MySQL email archive. | |
