production:
  adapter: mysql
  database: redmine
  host: localhost
  port: 3306
  username: redmine
  password: 123456
  encoding: utf8</pre></li>
安裝 
cd /opt/redmine-1.2.1
rake generate_session_store
RAILS_ENV=production rake db:migrate
RAILS_ENV=production rake redmine:load_default_data

mkdir tmp public/plugin_assets
sudo chown -R redmine:redmine files log tmp public/plugin_assets
sudo chmod -R 755 files log tmp public/plugin_assets</pre></li>
啟動

此時可以通過 http://127.0.0.1:3002 來訪問 redmine 了 


redmine 郵件配置 
# vim /opt/redmine-1.2.1/config/email.yml

# Outgoing email settings
production:
  delivery_method: :async_smtp
  smtp_settings:
    enable_starttls_auto: true
    address: smtp.gmail.com
    port: 587
    domain: gmail.com
    authentication: :login
    user_name: ping.bao.cn@gmail.com
    password: redmine123456
    tls: true
對于gmail啟用了ssl的情況下，需要修改如下配置
