1、[root@localhost bin]# ./MySQLd_safe –skip-grant-tables
出现以下信息:
- Installing MySQL system tables…
 - 090724 12:05:13 [Warning] option ‘max_join_size’:
 
unsigned value 18446744073709551615 adjusted to 4294967295- 090724 12:05:13 [Warning] option ‘max_join_size’:

 - 090724 12:05:13 [Note] /usr/local/MySQL5/libexec/MySQLd: Shutdown complete
 - Installation of system tables failed!
 - 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!
