- Examine the logs in /var/lib/MySQL5 for more information.
- You can try to start the MySQLd daemon with:
- /usr/local/MySQL5/libexec/MySQLd –skip-grant &
- and use the command line tool
- /usr/local/MySQL5/bin/MySQL to connect to the MySQL
- database and look at the grant tables:

- shell> /usr/local/MySQL5/bin/MySQL -u root MySQL
- MySQL> show tables
- Try ‘MySQLd –help’ if you have problems with paths. Using –log
- gives you a log in /var/lib/MySQL5 that may be helpful.
