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:  
  
  
http://www.knowsky.com/  
  
  
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.  
  
  
The latest information about MySQL is available on the web at  
  
  
http://www.MySQL.com  
  
  
Please consult the MySQL manual section: ‘Problems running MySQL_install_db’,  
  
  
and the manual section that describes problems on your OS.  
  
  
Another information source is the MySQL email archive.  
  
  
Please check all of the above before mailing us!  
  
  
And if you do mail us, you MUST use the /usr/local/MySQL5/bin/MySQLbug script!
