The following are requirements for your server or web hosting:
- PHP 5.6.4 (7.0 recommended)
- MariaDB 10.0 or above, or MySQL 5.1 (5.6 or above recommended)
- 1 processor core
- 1GB RAM
- 100MB hard disk space (SSD recommended)
Additional hard disk space is required for the storage of your photos. As well as the original image, a number of thumbnails will be stored, so allow for twice the file size of each photo when calculating how much storage you need.
Alternatively, you can connect a cloud storage service to Blue Twilight to store your photos in “the cloud.” Blue Twilight supports Amazon S3 (and S3-compatible services such as Digital Ocean Spaces, Linode Object Storage and Dreamhosts), OpenStack (such as Memstore and OVH), Dropbox and Backblaze B2.
The following PHP modules are required (these are fairly standard and should be enabled on most web hosting packages):
- MySQL (PDO MySQL)
- XML (dom and simplexml)
