修改/user/local/redmine-1.3.1/config/environment.rb文件，在适当位置增加如下内容：
config.action_controller.session = { :key => "_redmine_session", :secret => "aa3be4f950045ce76451b8197bf06b6d" }
然后执行：
rake db:migrate RAILS_ENV="production"         //创建表
rake redmine:load_default_data RAILS_ENV="production"

如果报错：
rake aborted!
