Mastodon

Setting up a Masotdon server on Debian is somewhat annoying, due to the node- and ruby-based implementation. Most guides involve downloading and installing a large number of sources outside of APT. There's little need for such vulgarisms.

My running install uses the 3.2 branch of Mastodon atop Debian Unstable.

First, determine your domain name. You'll likely be serving Mastodon as a virtual host in your main nginx/apache config, so give it its own, distinct FQDN. It is not trivial to change your server's name later (it will, at a minimum, break existing federations), so choose wisely.

System work

• Via APT, install nodejs, redis-server, ruby-redis, rake, rbenv, ruby-bundler, postgresql-contrib, libpq-dev, libprotobuf-dev, protobuf-compiler, libidn11-dev, and yarnpkg ("yarn").
  • You will now have a PostgreSQL instance running on localhost:tcp/5432, if you didn't before.
  • You will now have a Redis instance running on localhost:tcp/6379, if you didn't before.
• So far as I can tell, you must now symlink /usr/bin/yarnpkg to yarn in some PATH directory:
  • ln -s /usr/bin/yarnpkg /usr/local/bin/yarn
• Prep the database:
  • echo "CREATE USER mastodon CREATEDB;" | sudo -u postgres psql
• Create mastodon user (salt to taste):
  • sudo adduser --disabled-login --gecos "Mastodon service account" mastodon

User work

Remaining work will be done as the mastodon user, in its home directory.

• git clone https://github.com/tootsuite/mastodon.git ~/live
• cd live
• bundle config set --local deployment true
• bundle config set --local without development:test
• bundle install
• RAILS_ENV=production bundle exec rake mastodon:setup
  • Use the same PostgreSQL user name you created earlier.
  • So far as I can tell, use a blank password for PostgresQDL and Redis.
  • I do (n)ot upload files to the "cloud", whatever that even means
