Equip unlimited storage & bandwidth with Humhub instance, using AWS S3 & Cloudfront (Signed-url) , fuse & s3fs, Nginx.

...without modifying Humhub (almost) ! Here's the steps & files that you'll need.

Overview:

Get unlimited storage:

• Mounting S3 Using s3fs
  • Example: fstab.txt
• Use s3fs on /path/to/humhub/uploads
• Your access goes through Symlink /path/to/humhub/uploads -> mountpoint /path/to/mountpoint/uploads -(s3fs)-> s3

Get unlimited bandwidth (with security):

Securing contents with Signed-url.

• Use s3fs on assets, static & themes
• Secure /uploads/files/* on Cloudfront with Behaviors setting
• Redirect access for uploaded files on Humhub into CDN, using Nginx rewrite
  • Example: nginx_humhub.conf
  • Assume your Humhub using Pretty URLs
• Write redirector that checks your $_SESSSION & privileges, then redirects into CDN with signed-url
  • Example: r.php
  • Place r.php on same directory with /path/to/humhub/index.php

Less pain on file download

• JS to add &filename= on href attribute, for passing original filename into CloudFront functions
  • Example views_layouts/head.php
  • Place the code in your theme, views/layouts/head.php
• CloudFront functions to add content-disposition response header from query string
  • Example: filename-viewer-response.js
  • Associate this function for Viewer response on behavior of your distribution
