1. Download the latest version from instantrails.rubyforge.org.
2. Use recommended tool [7-zip] to unzip the file.
3. If Apache has already been installed. go to 『\InstantRails\apache\conf』 and open httpd.conf [Apache setting file]. Change 『Listen 80″ to 『Listen xxx』 and 『Port 80″ to 『Port xxxx』
4. [for Windows] Double click on InstantRails.exe to start InstantRails.
InstantRails is self-contained-it doesn’t install itself into our global Windows environment. Therefore, it will not conflict with Apache Server that has already been installed on our machine. As long as we use different port, things will work fine.
InstantRails contains Apache and mySQL. If a machine has mySQL installed, we can change its port by going to 『program files—>mySQL—>mySQL Server x.x—->MySQL Server Instance Cinfig Wizard』
