Stop updating the fav_string attribute on posts. The column still exists on the table, but is no longer used or updated. Like the pool_string in7d503f08, the fav_string was used in the past to facilitate `fav:X` searches. Posts had a hidden fav_string column that contained a list of every user who favorited the post. These were treated like fake hidden tags on the post so that a search for `fav:X` was treated like a tag search. The fav_string attribute has been unused for search purposes for a while now. It was only kept because of technicalities that required departitioning the favorites table first (340e1008e) before it could be removed. Basically, removing favorites with `@favorite.destroy` was slow because Rails always deletes object by ID, but we didn't have an index on favorites.id, and we couldn't easily add one until the favorites table was departitioned. Fixes #4652. See https://github.com/danbooru/danbooru/issues/4652#issuecomment-754993802 for more discussion of issues caused by the fav_string (in short: write amplification, post table bloat, and favorite inconsistency problems).
Quickstart
Run this to start a basic Danbooru instance:
curl -sSL https://raw.githubusercontent.com/danbooru/danbooru/master/bin/danbooru | sh
This will install Docker Compose and use it to start Danbooru. When it's done, Danbooru will be running at http://localhost:3000.
Alternatively, if you already have Docker Compose installed, you can just do:
wget https://raw.githubusercontent.com/danbooru/danbooru/master/docker-compose.yaml
docker-compose up
Manual Installation
Follow the INSTALL.debian script to install Danbooru.
The INSTALL.debian script is written for Debian, but can be adapted for other distributions. Danbooru has been successfully installed on Debian, Ubuntu, Fedora, Arch, and OS X. It is recommended that you use an Ubuntu-based system since Ubuntu is what is used in development and production.
See here for a guide on how set up Danbooru inside a virtual machine.
For best performance, you will need at least 256MB of RAM for PostgreSQL and Rails. The memory requirement will grow as your database gets bigger.
In production, Danbooru uses PostgreSQL 10.18, but any release later than this should work.
Troubleshooting
If your setup is not working, here are the steps I usually recommend to people:
-
Test the database. Make sure you can connect to it using
psql. Make sure the tables exist. If this fails, you need to work on correctly installing PostgreSQL, importing the initial schema, and running the migrations. -
Test the Rails database connection by using
bin/rails console. RunPost.countto make sure Rails can connect to the database. If this fails, you need to make sure your Danbooru configuration files are correct. -
Test Nginx to make sure it's working correctly. You may need to debug your Nginx configuration file.
-
Check all log files.
