CANNOT get Ruby to work with SQL

Corne Lombaard

5/1/2008 12:00:00 PM

Please can someone help me?

I get the following error message when I start the rails server and I
click on About your application environment.

Errno::ENOENT in Rails/infoController#properties

No such file or directory - /tmp/mysql.sock

RAILS_ROOT: /home/corne/Studies/Ruby/Sites/demo

If I did a mysql> show variables like '%sock%' I get
the following:

/var/lib/mysql/mysql.sock

I do not know anything about Ruby, Linux, Sockets or the rest. Please
can someone tell me where to put this information or how do I setup my
database so that it works with Ruby?

A quick Google[0] shows this link:
<http://abstractplain.net/blog/..., which mentions that you can
modify the database.yml file to include a path to your socket file.

Also, Rails questions (and this is a question about Rails, and not a
general 'Ruby and SQL' question) are better off asked to the Rails
community[1].

[Note: parts of this message were removed to make it a legal post.]

Rails apps use a database configuration file,
<path-to-your-rails-app>/config/database.yml. When using mysql, there's
often a line in the file for each database like

socket: /tmp/mysql.sock

You could replace that path with the one from your error message,
/var/lib/mysql/mysql.sock. Alternatively, you could just remove the "socket"
lines from the file. I'm on Mac OS X, and I installed mysql via macports. I
find that I don't need to specify the location of the socket, so I just
delete that line.

For future issues with Rails, you should consult the rails-talk mailing
list, http://groups.google.com/group/rubyon... .

Good luck,
Craig
