Installation

It is recommended that you install Danbooru on a Debian-based system since most of the required packages are available on APT. Danbooru has been successfully installed on Fedora, CentOS, FreeBSD, and OS X. The INSTALL.debian install script is straightforward and should be simple to adapt for other platforms.

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.

On production Danbooru uses PostgreSQL 9.4, but any 9.x release should work.

Use your operating system's package management system whenever possible. This will simplify the process of installing init scripts, which will not always happen when compiling from source.

Troubleshooting

These instructions won't work for everyone. If your setup is not working, here are the steps I usually recommend to people:

1. 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.

2. Test the Rails database connection by using rails console. Run Post.count to make sure Rails can connect to the database. If this fails, you need to make sure your Danbooru configuration files are correct.

3. Test Nginx to make sure it's working correctly. You may need to debug your Nginx configuration file.

4. Check all log files.
