Questions and Answers
Q: My database seems b0rked
A: Try these magic incantations, it will try to fix broken databases:
mysqlcheck -r -u mythtv -pmythtv mythconverg
If you only want to check which part of the data base that is broken, run mysqlcheck without the -r.
Q: When running mysqlcheck I get the error message "Access denied for user ..."
A: The problem may be that you are using the wrong password. The following commands will change the mysql password to "mythtv":
# mysql -u root mysql
mysql> UPDATE user SET Password=PASSWORD('mythtv') WHERE user='mythtv';
mysql> FLUSH PRIVILEGES;
mysql> quit
Note that you will have to change the database password in the mythtv setup to "mythtv" once you get it running again.
Q: I'm getting a SQL error from mythbackend when upgrading. What does that mean?
A: Try using perror to get more information
