About
Mastodon consists of multiple components, including:
- the Mastodon application software (mainly Ruby and JavaScript)
- ...which runs under Ruby on Rails
- redis, an "in-memory database server" aka "dictionary" (see Wikipedia)
- Yarn, an application package manager for Node.js
- PostgreSQL - SQL database[1]
- a web server - typically nginx, but Apache also works
- Node.js
- Ruby - language used for most server-side operations
- Bundler - application package manager for Ruby, packaged as a Ruby Gem
- Ruby on Rails - application framework
- utilities:
- ffmpeg - for conversion of GIFs to MP4s[1]
- imagemagick - for the usual purposes
Files
- application: typically /home/<mastodon_user>/<mastodon> - but really, anywhere under the Mastodon user's home folder should work
- /home/<mastodon_user>/live/.env.production: main config file (for stuff not covered by UI)
- PostgreSQL logs (usually in /var/log/postgresql)
Local Notes
- Woozle attempts to install Mastodon, several times
