Loosely following these instructions...

I just do everything in root rather than using sudo, because that's how I roll.

Things done:

• Create droplet (4GB- 2CPU - 80GB - $20, Ubuntu 16.04, SFO2, IPv6, Gonzo key)
• apt update
• apt upgrade
• install node.js:
  • curl -sL https://deb.nodesource.com/setup_6.x | sudo bash -
  • apt install imagemagick ffmpeg libpq-dev libxml2-dev libxslt1-dev nodejs
  • npm install -g yarn
• install redis-server:
  • apt install redis-server redis-tools
• install PostgreSQL (Pg):
  • apt install postgresql postgresql-contrib
• switch to postgres user, create Mastodon user in Pg:
  • su - postgres
  • psql
  • CREATE USER mastodon CREATEDB;
  • \q

Now, we're trying to enable ident auth in Pg so users can log in without a password.

• I don't understand why we want to do this; seems like bad security.
• I tried to do this bit exactly as written, because it looked like it might be user-sensitive, but it didn't work (see below).
• Can this be done as all one line?

• sudo sed -i '/^local.*postgres.*peer$/a host all all 127.0.0.1/32 ident' \
• /etc/postgresql/9.?/main/pg_hba.conf

That didn't work, because after the second line it asked for a password for postgres, which I don't have, and wouldn't accept a blank. So, backing out and trying as root (and all one line):

• sed -i '/^local.*postgres.*peer$/a host all all 127.0.0.1/32 ident' /etc/postgresql/9.?/main/pg_hba.conf

No error, but also no success message. I will assume successful.

• install ident daemon:
  • apt install pidentd
  • systemctl enable pidentd
  • Response:
    • pidentd.service is not a native service, redirecting to systemd-sysv-install
    • Executing /lib/systemd/systemd-sysv-install enable pidentd
  • systemctl start pidentd
  • systemctl restart postgresql

Setting Up Ruby

• apt install autoconf bison build-essential libssl-dev libyaml-dev libreadline6-dev zlib1g-dev libncurses5-dev libffi-dev libgdbm3 libgdbm-dev
• adduser --disabled-password --disabled-login mastodon
  • Just hitting ENTER in response to all questions, "Y" in response to "Y/n".
• Change to user mastodon:
  • su - mastodon
