Dear list:

I have one app running merrily on a Linux box. I can run “rake  
migrate” on it with no trouble, start it, stop it, and restart it.

I created a second app and uploaded it to the same box. Aside from the  
database names, the database.yml files are _exactly the same_.

## Yet when I run “rake migrate” on the new app, I get:

## (in /home/[USERNAME]/rails/[APPNAME]/releases/20061113210744) \*\* Invoke migrate (first\_time) \*\* Invoke db:migrate (first\_time) \*\* Invoke environment (first\_time) \*\* Execute environment \*\* Execute db:migrate rake aborted! getaddrinfo: Name or service not known /usr/local/ruby/lib/ruby/gems/1.8/gems/activerecord-1.14.4/lib/active\_record/vendor/mysql.rb:108:in `initialize’ …[et cetera]

Can anyone give me a hint where to start to investigate this? Should I  
be updating my Rails, or my MySQL driver? Any pointers in the right  
direction would be greatly appreciated.

Did you ever get an answer to this?  
I am getting a similar error when I try to do:  
rake db:structure:dump --trace  
(in /home/…)  
\*\* Invoke db:structure:dump (first\_time)  
\*\* Invoke environment (first\_time)  
\*\* Execute environment  
\*\* Execute db:structure:dump  
rake aborted!  
getaddrinfo: Name or service not known  
…/vendor/rails/activerecord/lib/active\_record/vendor/mysql.rb:111:in  
`initialize’  
etc.
