Examine the logs in /usr/local/mysql/var for more information. You can try to start the mysqld daemon with: shell> /usr/local/mysql/libexec/mysqld --skip-grant & and use the command line tool /usr/local/mysql/bin/mysql to connect to the mysql database and look at the grant tables: shell> /usr/local/mysql/bin/mysql -u root mysql mysql> show tables Try 'mysqld --help' if you have problems with paths. Using --general-log gives you a log in /usr/local/mysql/var that may be helpful.
