It was not easy as doing apt-get install redmine from console. Yes, the command is exist. But not automatically run as I ran apt-get install phpmyadmin. I was follow http://www.redmine.org/wiki/redmine/HowTo_Install_Redmine_in_Ubuntu#Ubuntu-104-using-Passenger. But still no luck.
I also read http://www.redmine.org/boards/2/topics/16811. But still fail. Then I found Bitnami. I saw that Bitnami has Redmine package in Linux format. So I tried to download it.
After download it, I did :
- chmod a+x bitnami_installer
- run the installer by type : ./bitname_installer
Now you can access it via http://localhost:port_number/redmine
