This Redmine plugin makes file attachments be stored on Amazon S3 rather than on the local filesystem. This is a fork for original gem and difference is that this one supports Redmine 2

1. Make sure Redmine is installed and cd into it's root directory
2. git clone git://github.com/ka8725/redmine_s3.git plugins/redmine_s3
3. cp plugins/redmine_s3/config/s3.yml.example config/s3.yml
4. Edit config/s3.yml with your favourite editor
5. bundle install --without development test for installing this plugin dependencies (if you already did it, doing a bundle install again whould do no harm)
6. Restart mongrel/upload to production/whatever
7. Optional: Run rake redmine_s3:files_to_s3 to upload files in your files folder to s3
8. rm -Rf plugins/redmine_s3/.git

• The bucket specified in s3.yml will be created automatically when the plugin is loaded (this is generally when the server starts).
• Deprecated (no longer supported, specify endpoint option instead) If you have created a CNAME entry for your bucket set the cname_bucket option to true in s3.yml and your files will be served from that domain.
• After files are uploaded they are made public, unless private is set to true.
• Public and private files can use HTTPS urls using the secure option
• Files can use private signed urls using the private option
• Private file urls can expire a set time after the links were generated using the expires option
• If you're using a Amazon S3 clone, then you can do the download relay by using the proxy option.
