機器安裝的是Ubuntu Server 12.04，有兩種方法配置。
一、apache2 Passenger
1.install redmine:
sudo apt-get install redmine redmine-mysql libapache2-mod-passenger
2.reconfiguration redmine:
sudo dpkg-reconfigure redmine
configuration file, /etc/redmine/default/database.yml
3.link redmine to apache2
sudo ln -s /usr/share/redmine/public/ /var/www/redmine
4.In /etc/apache2/mods-available/passenger.conf, add:
PassengerDefaultUser www-data
5.In /etc/apache2/sites-available/default by adding:
<Directory /var/www/redmine>
RailsBaseURI /redmine
PassengerResolveSymlinksInDocumentRoot on
</Directory>
6.sudo service apache2 restart
Maybe sudo chmod a+x /usr/share/redmine/public
7.http://192.168.2.111/redmine/
二、webrick (lightweight less memory)
cd /usr/share/redmine/
A、創建一個session安裝密鑰
rake generate_session_store
B、初始化Redmine的數據庫結構
RAILS_ENV=production rake db:migrate
C、導入缺省配置數據
RAILS_ENV=production rake redmine:load_default_data
注：這一步操作是可選的，此命令將導入默認角色、跟蹤標簽、狀態、工作流程和枚舉值(強烈推薦執行它),您也可以從頭開始一步步填寫自己的配置參數。
D、Add /etc/init/redmine.conf
# Redmine
description "Redmine"
start on runlevel [2345]
stop on runlevel [!2345]
expect daemon
exec ruby /usr/share/redmine/script/server webrick -e production -b 0.0.0.0 -d
E、sudo service redmine start
F、http://192.168.2.111:3000/
