http://www.redmine.org/projects/redmine/wiki/HowTo_Install_Redmine_on_Ubuntu_step_by_step
解决使用了下面三步：
1， apt-get install libapache2-mod-passenger
2，a2enmod passenger
3，service apache2 restart
问题解决，apache正常启动，但是redmine运行报错。
报错如下：

由于从来未接触过ruby，看代码，估计所依赖不足（缺少依赖）导致。
http://hooney.iteye.com/blog/259744 这个文章很有帮助。
参照http://itecsoftware.com/install-redmine-using-passenger-via-apache-on-ubuntu-10-04安装号passenger
然后其它全部使用gem install 安装其它依赖即可。参考：http://stackoverflow.com/questions/16376010/ubuntu-cannot-install-rmagick
