This is to setup a Content delivery network
You need an account with Amazon
- Create Distribution
- Delivery Method: Download
- Choose Custom Origin
- Origin DNS Name is the domain name of your site ex.: info.tiki.org
- Protocol Policy: HTTP Only (unless you know what you are doing)
- HTTP Port: leave at the default 80 (unless you know what you are doing)
- Allowed Connections: HTTP and HTTPS
- CNAMEs: leave empty unless you know what you are doing
- Default Root Object: leave empty if your siteis at the root. Otherwise, put the subdirectory (ex.: 7x/)
- Loggin: Off
- Comments: You can put a comment here to distinguish this distribution from the others.
- Distribution Status: Enabled
- Click "continue"
- Wait a while for the distribution to be active
- Find out your domain name which should be something like abcde12345.cloudfront.net
- visit http://abcde12345.cloudfront.net/pics/icons/error.png (using the exact domain name provided by cloudfront)
- This should confirm if it's working. It can take a bit of time before DNS has propagated. If you see a little image, it means the CDN is active.
- go the performance admin panel of your Tiki instance
- Content Delivery Network: http://abcde12345.cloudfront.net/
- Content Delivery Network (in SSL): https://abcde12345.cloudfront.net/
- Then "view source" of pages rendered by Tiki and you should see abcde12345.cloudfront.net in the code
- Empty your cache by visiting tiki-admin_system.php?do=all
A: Custom Origin is much simpler. No need to upload your files to S3. CloudFront takes care of fetching a copy from the original site. Using S3 would be a lot of work because you would have to keep your files in sync. While this could work for images, this is especially problematic for generated files like minified CSS files.
Q: The limited Tiki documentation for CDN says its only for static images and jquery code: would just this subset being CDN'd make any significant difference?
A: Yes, because these files are needed for everyone, whatever the page they visit, vs the download of 1 file. If you do Yahoo! YSlow and Google PageSpeed analysis, you will see that images, JS and CSS are a huge factor.
Q: I use file storage for File Galleries etc - so CDN'ing these could be really useful for improving downloads for some users - but I guess it would not be possible to somehow CDN these?
A: Not with code in Tiki7, but that's a great idea.
Q: When Tiki is set up for CDN, I assume it automatically adds the amazon domain prefix - but presumably only to designated folders (for static images and jquery code?) what is the exact scope of this?
