record of fixes
e.g., October 7th. 2007
Hi Prof White,
It seems that the MySQL database service died. I'll review the /var/log/mysqld.log file to see if I can figure out why. To get it started again, I did: su - root (this allows you to become the "root" or administrator user) Password: type this service mysqld restart tells the MySQL service to stop (or be killed if it is "frozen") and then start again.
The command "service" can be run at any level in the Unix directory when you are the root user because its absolute location, /sbin/service, is in the PATH. This will not work as a normal user, such as your normal login.
This is all a fix for the Oct 7:
MediaWiki internal error.
Original exception: exception 'DBQueryError' with message 'A database error has occurred Query: SELECT value,exptime FROM `mw_objectcache` WHERE keyname='mediawiki-mw_:messages-hash' Function: MediaWikiBagOStuff::_doquery Error: 1033 Incorrect information in file: './mediawiki/mw_objectcache.frm' (localhost) ' in /home/intersci/wiki/includes/Database.php:806 Stack trace: #0 etc
