One database per project with multiple projects?

Added by Ed Beaty over 14 years ago

Hello, all. I have several projects, and need to have each project use its own database (I'm migrating from a system where project A had an Issue #1 and project B had and Issue #1, and I need to preserve the numbering of these old bugs).

I'm using redmine through Mongrel Clusters, served by Apache. I'm able to create the databases in mysql:
create database projectA character set utf8;
create database projectB character set utf8;

and setup the tables:
sudo rake db:migrate RAILS_ENV="projectA"
sudo rake db:migrate RAILS_ENV="projectB"

sudo rake redmine:load_default_data RAILS_ENV="projectA"
sudo rake redmine:load_default_data RAILS_ENV="projectB"

and setup the database.yml:
adapter: mysql
database: projectA
host: localhost
username: *
password: *

adapter: mysql
database: projectB
host: localhost
username: *
password: *

But when I try to configure mongrel_rails, I can't figure out how to make it serve the projects with different databases.

If I do:
sudo mongrel_rails cluster::configure -e projectA -p 8000 -N 3 -c /home/redmine --user apache --group apache

then any issues I add to Project B get put in the Project A database.
If I leave out the -e projectName argment, I get this error in my mongrel log:

  • Daemonized, any open files are closed. Look at tmp/pids/ and log/mongrel.9000.log for info.
  • Starting Mongrel listening at

  • Starting Rails with development environment...

    from /usr/bin/mongrel_rails:19:in `load'

Any ideas on how to make this work? I don't HAVE to use Mongrel; it's just that I was able to get a single-database multiple-project setup working with it pretty
easily. If there's a non-mongrel way to run Redmine through apache, I'm game.

Thanks for all your help.
