Problems connecting to remote mysql db

Hi,

I am having a problem connecting to a remote mysql db and I can’t
figure out what the problem is. When I try to connect I get the error:

getaddrinfo: no address associated with hostname.

I have looked all over for clues as to what that means but I haven’t
been able to find anything that helps. I have no problems connecting
to the database with php and with the mysql query browser, I only have
problems connecting with rails and the settings in database.yml
correspond to the settings I have in php. I also don’t have any
problem connecting to the mysql db on my local machine. I have also
tried it on Windows and Mac OSX and I get the same error on both
platforms.

The remote db version is MySQL 4.0.15-standard. I have also granted
privelages for the user I am connecting with for all domains.

The trace gives me:

If anyone has an idea about what is going on I would really appreciate
it.

Thanks,

make sure that there are no tab characters in database.yml, only spaces
as separators.

gettaddinfo: no address associated with hostname means that the ‘host’
name listed within database.yml so it would seem that the problem is
either a typo or use of tabs instead of spaces

Craig,

Thank you very much. I didn’t have any tab characters in my
database.yml file (although I didn’t know that and it is a useful
thing to know) but that led me to the right answer. The problem was
that I had the port number as part of the host with the host.

I had the host set like I did in php

host: my.domain.com:3306

and I found an example of the correct way

host: my.domain.com
port: 3306

Thanks again,
Jake
