Login using FTP to your account, and create a directory on the home of your account ("appname") and upload your application there (folders app, config, public, etc)
Then:
1. First, you will need SSH access to your account, you will have to request this from support by emailing support@hostony.com or posting a trouble ticket. You will also need an SSH application such as Putty.
2. Now, login to your account using SSH and navigate to your home directory.
CODE
cd ~
3. Next create/update your Rails application by typing:
CODE
rails appname
4. Now, you will need to create a symbolic link to the public directory of this app. This will make it accessible on the web server.
CODE
ln -s ~/appname/public ~/public_html/appshortname
5. You will now be able to access your Rails app at http://yourdomain.com/appshortname/
6. If you want your Rails application to be accessible from the root directory, you can do the following. Only try this if you don’t have any other content in your public_html directory
CODE
mv public_html public_html_back
ln -s ~/appname/public ~/public_html
ln -s ~/appname/public ~/public_html
Enjoy!
