Redmine Upgrade Notes Raw See Rendered

Not as peachy as I thought.

## Upgrade Redmine

    RAILS_ENV=production rake db:migrate_plugins  
        NEEDED Rails 2.1.2  
        gem install rails -v=2.1.2

-   MAKE SURE that all files are owned by mongrel:mongrel

        chown -R mongrel:mongrel your_rails_app

-   Mongrel app server was originally started with:

        /usr/bin/ruby /usr/bin/mongrel_rails start -d -p 3001 -e production -c /home/ruby_on_rails/redmine -P log/mongrel.pid --user mongrel --group mongrel --prefix=/redmine

-   Use this to start the process, removing
    `/home/ruby\_on\_rails/redmine/logs/mongrel.pid` if you run into
    any errors about this file.

Change to the **/home/rub\_on\_rails** directory before issuing the
command.

    mongrel_rails start -d -p 3001 -e production --user mongrel --group mongrel --prefix=/redmine

## Other Notes

-   Sometimes, deleting `source_cache` helps with update process
-   Location ascertained by gem env. Default at `/usr/<local>/lib/ruby`
-   [Might also need to install 'rack' to run gem
    update](http://rubyforge.org/frs/?group_id=3113&release_id=40490)
