Sounds like the frontend user (normally 'mythtv') does not have access
A backend often runs as a mysql 'root' user...and mysql usually installs
with NO PASSWORD on a root user. So the backend can work and the front
So, first, can you get to the mysql console ( a 'mysql>' prompt) on the
backend machine as root?
I presume that the Backend also hosts the mysql database, otherwise you
need to be on that machine.
$ mysql -u root -p <Enter>
Enter Password: (Hit Enter or enter the password).
mysql> use mysql; # This is the mysql admin database
mysql> select host,user,password from user; # The 'user' table has
field 'user'...clear as mud, right?
This will print out the allowed users, their hosts and a hash
representing their password. something like:
mysql> select host,user,password from user;
| host | user | password |
| localhost | root | 1b3ab4920bfa6d2a |
| tor1.mandamus.org | root | 1b3ab4920bfa6d2a |
| 127.0.0.1 | root | 1b3ab4920bfa6d2a |
| localhost | mythtv | 0476fc026afffe24 |
| tor1.mandamus.org | mythtv | 0476fc026afffe24 |
In your case you need the mythtv user to be from a different host.
This is the mc.sql script, which probably exists on your install, but
may not...You need to adjust it as necessary. Replace 'localhost' with
your ...101 or the hostname (presumes that the machine is listed in
CREATE DATABASE IF NOT EXISTS mythconverg;
GRANT ALL ON mythconverg.* TO mythtv at localhost IDENTIFIED BY "mythtv";
GRANT CREATE TEMPORARY TABLES ON mythconverg.* TO mythtv at localhost
IDENTIFIED BY "mythtv";
ALTER DATABASE mythconverg DEFAULT CHARACTER SET utf8 COLLATE
Run this, on the backend machine by:
$ mysql -u root -ppassword < mc.sql
You should also add a password for the mysql root user if one does not

Please let me know if anything I say offends you.
I may wish to offend you again in the future.
