[mythtvnz] changing mythweb ipaddress for mysql

[Daniel Hughes]

Since changing the IPAddress of my myth backend I get the following
message when trying to use mythweb:

!!NoTrans: Can't connect to MySQL server on '192.168.1.3' (4) [#2003]

That IP Address is the old address. So I need to change it to the new address.

How do I do that?

https://www.mythtv.org/wiki/MythWeb#Installation indicates that there
is a config file at /etc/apache2/modules.d/mythweb.conf however I
don't have modules.d folder

That page also has zero information about how to configure the IP
Address of the database for use the MythWeb.

How do I fix my install?
