 568 also try to start the mysqld daemon with:
 569
 570 /usr/sbin/mysqld --skip-grant &

 572 You can use the command line tool mysql to connect to the mysql

 574
 575 shell> mysql -u mysql mysql

 578 Try 'mysqld --help' if you have problems with paths. Setting on
 579 logging in $MYSQL_DATA_DIR/mysqld.conf gives you a log in /var/log/mysql/query.log that
 580 may be helpful. The latest information about MySQL is available on the
