What is Vanta Interactive Social?

VantaInteractive/Social is a fork of Mastodon Glitch Edition, with some upstream PRs merged, some features from the archived koyu.space, and our own changes on top, in order for them to be used on the social.vantainteractive.com subdomain. Vanta Interactive Social is a server instance that doesn't accept new users, as it's meant to be exclusively used by Vanta Interactive members.

The standalone installation guide is available on the Mastodon documentation website, and below, for ease of access:

Preparing your machine

If you are setting up a fresh machine, it is recommended that you secure it first. Assuming that you are running Ubuntu 22.04 or Debian 12, or newer:

Do not allow password-based SSH login (keys only)

First, make sure you are actually logging in to the server using keys and not via a password, otherwise, this will lock you out. Many hosting providers support uploading a public key and automatically set up key-based root login on new machines for you.

Edit /etc/ssh/sshd_config and find PasswordAuthentication. Make sure it’s uncommented and set to no. If you made any changes, restart sshd:

systemctl restart ssh.service

Update system packages

apt update && apt upgrade -y

Install fail2ban so it blocks repeated login attempts

First, install fail2ban:

apt install fail2ban

Edit /etc/fail2ban/jail.local and put this inside:

[DEFAULT]
destemail = your@email.here
sendername = Fail2Ban

[sshd]
enabled = true
port = 22
mode = aggressive

Finally, restart fail2ban:

systemctl restart fail2ban

Install a firewall and only allow SSH, HTTP and HTTPS ports

First, install iptables-persistent. During installation, it will ask you if you want to keep the current rules–decline.

apt install -y iptables-persistent

Edit /etc/iptables/rules.v4 and put this inside:

*filter

#  Allow all loopback (lo0) traffic and drop all traffic to 127/8 that doesn't use lo0
-A INPUT -i lo -j ACCEPT
-A INPUT ! -i lo -d 127.0.0.0/8 -j REJECT

#  Accept all established inbound connections
-A INPUT -m state --state ESTABLISHED,RELATED -j ACCEPT

#  Allow all outbound traffic - you can modify this to only allow certain traffic
-A OUTPUT -j ACCEPT

#  Allow HTTP and HTTPS connections from anywhere (the normal ports for websites and SSL).
-A INPUT -p tcp --dport 80 -j ACCEPT
-A INPUT -p tcp --dport 443 -j ACCEPT
#  (optional) Allow HTTP/3 connections from anywhere.
-A INPUT -p udp --dport 443 -j ACCEPT

#  Allow SSH connections
#  The -dport number should be the same port number you set in sshd_config
-A INPUT -p tcp -m state --state NEW --dport 22 -j ACCEPT

#  Allow ping
-A INPUT -p icmp -m icmp --icmp-type 8 -j ACCEPT

# Allow destination unreachable messages, especially code 4 (fragmentation required) is required or PMTUD breaks
-A INPUT -p icmp -m icmp --icmp-type 3 -j ACCEPT

#  Log iptables denied calls
-A INPUT -m limit --limit 5/min -j LOG --log-prefix "iptables denied: " --log-level 7

#  Reject all other inbound - default deny unless explicitly allowed policy
-A INPUT -j REJECT
-A FORWARD -j REJECT

COMMIT

With iptables-persistent, that configuration will be loaded at boot time. But since we are not rebooting right now, we need to load it manually for the first time:

iptables-restore < /etc/iptables/rules.v4

If your server is also reachable over IPv6, edit /etc/iptables/rules.v6 and add this inside:

*filter

#  Allow all loopback (lo0) traffic and drop all traffic to 127/8 that doesn't use lo0
-A INPUT -i lo -j ACCEPT
-A INPUT ! -i lo -d ::1/128 -j REJECT

#  Accept all established inbound connections
-A INPUT -m state --state ESTABLISHED,RELATED -j ACCEPT

#  Allow all outbound traffic - you can modify this to only allow certain traffic
-A OUTPUT -j ACCEPT

#  Allow HTTP and HTTPS connections from anywhere (the normal ports for websites and SSL).
-A INPUT -p tcp --dport 80 -j ACCEPT
-A INPUT -p tcp --dport 443 -j ACCEPT
#  (optional) Allow HTTP/3 connections from anywhere.
-A INPUT -p udp --dport 443 -j ACCEPT

#  Allow SSH connections
#  The -dport number should be the same port number you set in sshd_config
-A INPUT -p tcp -m state --state NEW --dport 22 -j ACCEPT

#  Allow ping
-A INPUT -p icmpv6 -j ACCEPT

#  Log iptables denied calls
-A INPUT -m limit --limit 5/min -j LOG --log-prefix "iptables denied: " --log-level 7

#  Reject all other inbound - default deny unless explicitly allowed policy
-A INPUT -j REJECT
-A FORWARD -j REJECT

COMMIT

Similar to the IPv4 rules, you can load it manually like this:

ip6tables-restore < /etc/iptables/rules.v6

Installing from source

Pre-requisites

• A machine running Ubuntu 22.04 or Debian 12 that you have root access to
• A domain name (or a subdomain) for the Mastodon server, e.g. example.com
• An e-mail delivery service or other SMTP server

System repositories

Make sure curl, wget, gnupg, apt-transport-https, lsb-release and ca-certificates are installed first:

apt install -y curl wget gnupg apt-transport-https lsb-release ca-certificates

Node.js

curl -fsSL https://deb.nodesource.com/gpgkey/nodesource-repo.gpg.key | gpg --dearmor -o /etc/apt/keyrings/nodesource.gpg
echo "deb [signed-by=/etc/apt/keyrings/nodesource.gpg] https://deb.nodesource.com/node_20.x nodistro main" | tee /etc/apt/sources.list.d/nodesource.list

PostgreSQL

wget -O /usr/share/keyrings/postgresql.asc https://www.postgresql.org/media/keys/ACCC4CF8.asc
echo "deb [signed-by=/usr/share/keyrings/postgresql.asc] http://apt.postgresql.org/pub/repos/apt $(lsb_release -cs)-pgdg main" > /etc/apt/sources.list.d/postgresql.list

System packages

apt update
apt install -y \
  imagemagick ffmpeg libpq-dev libxml2-dev libxslt1-dev file git-core \
  g++ libprotobuf-dev protobuf-compiler pkg-config gcc autoconf \
  bison build-essential libssl-dev libyaml-dev libreadline6-dev \

  nginx nodejs redis-server redis-tools postgresql postgresql-contrib \
  certbot python3-certbot-nginx libidn11-dev libicu-dev libjemalloc-dev

Yarn

corepack enable
yarn set version classic

Installing Ruby

We will use rbenv to manage Ruby versions as it simplifies obtaining the correct versions and updating them when new releases are available. Since rbenv needs to be installed for an individual Linux user, we must first create the user account under which Mastodon will run:

adduser --disabled-login mastodon

We can then switch to the user:

su - mastodon

And proceed to install rbenv and rbenv-build:

git clone https://github.com/rbenv/rbenv.git ~/.rbenv
echo 'export PATH="$HOME/.rbenv/bin:$PATH"' >> ~/.bashrc
echo 'eval "$(rbenv init -)"' >> ~/.bashrc
exec bash
git clone https://github.com/rbenv/ruby-build.git "$(rbenv root)"/plugins/ruby-build

Once this is done, we can install the correct Ruby version:

RUBY_CONFIGURE_OPTS=--with-jemalloc rbenv install 3.2.3
rbenv global 3.2.3

We’ll also need to install the bundler:

gem install bundler --no-document

Return to the root user:

exit

Setup

Setting up PostgreSQL

Performance configuration (optional)

For optimal performance, you may use pgTune to generate an appropriate configuration and edit values in /etc/postgresql/16/main/postgresql.conf before restarting PostgreSQL with systemctl restart postgresql

Creating a user

You will need to create a PostgreSQL user that Mastodon could use. It is easiest to go with “ident” authentication in a simple setup, i.e. the PostgreSQL user does not have a separate password and can be used by the Linux user with the same username.

Open the prompt:

sudo -u postgres psql

In the prompt, execute:

CREATE USER mastodon CREATEDB;
\q

Done!

Setting up Mastodon

It is time to download the Mastodon code. Switch to the mastodon user:

su - mastodon

Checking out the code

Use git to download the latest stable release of Mastodon:

git clone https://github.com/VantaInteractive/Social.git live && cd live
git checkout $(git tag -l | grep '^v[0-9.]*$' | sort -V | tail -n 1)

Installing the last dependencies

Now to install Ruby and JavaScript dependencies:

bundle config deployment 'true'
bundle config without 'development test'
bundle install -j$(getconf _NPROCESSORS_ONLN)
yarn install --pure-lockfile

The two bundle config commands are only needed the first time you’re installing dependencies. If you’re going to be updating or re-installing dependencies later, just bundle install will be enough.

Generating a configuration

Run the interactive setup wizard:

RAILS_ENV=production bundle exec rake mastodon:setup

This will:

• Create a configuration file
• Run asset precompilation
• Create the database schema

The configuration file is saved as .env.production. You can review and edit it to your liking. Refer to the Mastodon documentation on configuration.

You’re done with the mastodon user for now, so switch back to root:

exit

Acquiring an SSL certificate

We’ll use Let’s Encrypt to get a free SSL certificate:

certbot certonly --nginx -d example.com

This will obtain the certificate, and save it in the directory /etc/letsencrypt/live/example.com/.

Setting up nginx

Copy the configuration template for nginx from the Mastodon directory:

cp /home/mastodon/live/dist/nginx.conf /etc/nginx/sites-available/mastodon
ln -s /etc/nginx/sites-available/mastodon /etc/nginx/sites-enabled/mastodon
rm /etc/nginx/sites-enabled/default

Then edit /etc/nginx/sites-available/mastodon to

1. Replace example.com with your own domain name
2. Uncomment the ssl_certificate and ssl_certificate_key lines and replace the two lines with (ignore this step if you are bringing your own certificate)

ssl_certificate     /etc/ssl/certs/ssl-cert-snakeoil.pem;
ssl_certificate_key /etc/ssl/private/ssl-cert-snakeoil.key;

3. Make any other adjustments you might need.

Un-comment the lines starting with ssl_certificate and ssl_certificate_key, updating the path with the correct domain name.

Reload nginx for the changes to take effect:

systemctl reload nginx

At this point, you should be able to visit your domain in the browser and see the elephant hitting the computer screen error page. This is because we haven’t started the Mastodon process yet.

Setting up systemd services

Copy the systemd service templates from the Mastodon directory:

cp /home/mastodon/live/dist/mastodon-*.service /etc/systemd/system/

If you deviated from the defaults at any point, check that the username and paths are correct:

$EDITOR /etc/systemd/system/mastodon-*.service

Finally, start and enable the new systemd services:

systemctl daemon-reload
systemctl enable --now mastodon-web mastodon-sidekiq mastodon-streaming

They will now automatically start at boot.

Note

Note that you can also start the server manually by running from anywhere, the following commands, but is not generally recommended unless you know what you're doing:

mastodon-sidekiq

RAILS_ENV=production DB_POOL=25 MALLOC_ARENA_MAX=2 LD_PRELOAD=libjemalloc.so /home/{user}/.rbenv/shims/bundle exec sidekiq -c 25

mastodon-streaming

NODE_ENV=production PORT=%i /usr/bin/node /home/{user}/live/streaming

mastodon-web

RAILS_ENV=production PORT=3000 LD_PRELOAD=libjemalloc.so /home/mastodon/.rbenv/shims/bundle exec puma -C config/puma.rb
