unzip redmine-2.5.1.zip
cd redmine-2.5.1
cd /var/www/
sudo mv ~/backup/redmine-2.5.1 ./redmine
cd redmine/config
cp database.yml.example database.yml
vi database.yml 修改数据库连接参数

cd backup/
sudo gem install --http-proxy http://127.0.0.1:3128 bundler
vi /var/www/redmine/Gemfile 查看, 不改动
到redmine根目录下
/opt/ruby-2.0.0/bin/bundle install --without development test rmagick
这一步如果网络不好, 要很长时间
然后是初始化数据库, 依次执行
RAILS_ENV=production /opt/ruby-2.0.0/bin/bundle exec /opt/ruby-2.0.0/bin/rake generate_secret_token
RAILS_ENV=production /opt/ruby-2.0.0/bin/bundle exec /opt/ruby-2.0.0/bin/rake db:migrate
RAILS_ENV=production /opt/ruby-2.0.0/bin/bundle exec /opt/ruby-2.0.0/bin/rake redmine:load_default_data
启动服务, 可以在最后加上 -d 参数后台运行
ruby script/rails server webrick -e production
ruby script/rails server webrick -e production -d
