DNS records should be added before anything is done on the server.
The records added are:
- A record (IPv4 address) for example.com
- AAAA record (IPv6 address) for example.com
Basic server setup (optional)¶
If you are setting up a fresh machine, it is recommended that you secure it first. Assuming that you are running Ubuntu 18.04:
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.
/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
Update system packages¶
apt update && apt upgrade -y
Install fail2ban so it blocks repeated login attempts¶
apt install fail2ban
/etc/fail2ban/jail.local and put this inside:
[DEFAULT] destemail = email@example.com sendername = Fail2Ban [sshd] enabled = true port = 22 [sshd-ddos] enabled = true port = 22
Finally restart fail2ban:
systemctl restart fail2ban
Configure firewall and only whitelist SSH, HTTP and HTTPS ports¶
UFW, or Uncomplicated Firewall, is a simple firewall already installed on your system. By default it's disabled, so you should really enable it for better security.
You will want to deny incoming traffic and allow outgoing traffic by default.
ufw default deny incoming ufw default allow outgoing
Next, allow SSH, HTTP, and HTTPS.
ufw allow ssh ufw allow 80 ufw allow 443
Finally, enable UFW.
You can use
ufw status to see the status of your firewall.
For more about UFW, see this article.
- A machine running Ubuntu 18.04 that you have root access to
- A domain name (or a subdomain) for the Soapbox Legacy server, e.g.
- An e-mail delivery service or other SMTP server
You will be running the commands as root. If you aren't already root, switch to root:
Make sure curl is installed first:
apt install -y curl
curl -sL https://deb.nodesource.com/setup_10.x | bash -
curl -sS https://dl.yarnpkg.com/debian/pubkey.gpg | apt-key add - echo "deb https://dl.yarnpkg.com/debian/ stable main" | tee /etc/apt/sources.list.d/yarn.list
- imagemagick - Soapbox Legacy uses imagemagick for image related operations
- ffmpeg - Soapbox Legacy uses ffmpeg for conversion of GIFs to MP4s
- libprotobuf-dev and protobuf-compiler - Soapbox Legacy uses these for language detection
- nginx - nginx is our frontend web server
- redis-* - Soapbox Legacy uses redis for its in-memory data structure store
- postgresql-* - Soapbox Legacy uses PostgreSQL as its SQL database
- nodejs - Node is used for Soapbox Legacy's streaming API
- yarn - Yarn is a Node.js package manager
- Other -dev packages, g++ - these are needed for the compilation of Ruby using ruby-build.
apt update apt install -y \ imagemagick ffmpeg libpq-dev libxml2-dev libxslt1-dev file git-core \ g++ libprotobuf-dev protobuf-compiler pkg-config nodejs gcc autoconf \ bison build-essential libssl-dev libyaml-dev libreadline6-dev \ zlib1g-dev libncurses5-dev libffi-dev libgdbm5 libgdbm-dev \ nginx redis-server redis-tools postgresql postgresql-contrib \ certbot python-certbot-nginx yarn libidn11-dev libicu-dev libjemalloc-dev
We will be using rbenv to manage Ruby versions, because it's easier to get the right versions and to update once a newer release comes out. rbenv must be installed for a single Linux user, therefore, first we must create the user Soapbox Legacy will be running as:
adduser --disabled-login soapbox
We can then switch to the user:
su - soapbox
And proceed to install rbenv and rbenv-build:
git clone https://github.com/rbenv/rbenv.git ~/.rbenv cd ~/.rbenv && src/configure && make -C src echo 'export PATH="$HOME/.rbenv/bin:$PATH"' >> ~/.bashrc echo 'eval "$(rbenv init -)"' >> ~/.bashrc exec bash git clone https://github.com/rbenv/ruby-build.git ~/.rbenv/plugins/ruby-build
Once this is done, we can install the correct Ruby version:
RUBY_CONFIGURE_OPTS=--with-jemalloc rbenv install 2.6.1 rbenv global 2.6.1
Default gem version shipped with ruby_2.6.0 is incompatible with latest bundler, so we need to update gem:
gem update --system
We'll also need to install bundler:
gem install bundler --no-document
Return to the root user:
Setting up PostgreSQL¶
Performance configuration (optional)¶
For optimal performance, you may use pgTune to generate an appropriate configuration and edit values in
/etc/postgresql/9.6/main/postgresql.conf before restarting PostgreSQL with
systemctl restart postgresql
Creating a user¶
You will need to create a PostgreSQL user that Soapbox Legacy could use. It is easiest to go with "ident" authentication in a simple setup, i.e. the PostgreSQL user does not have a separate password and can be used by the Linux user with the same username.
Open the prompt:
sudo -u postgres psql
In the prompt, execute:
CREATE USER soapbox CREATEDB; \q
Setting up Soapbox Legacy¶
It is time to download the Soapbox Legacy code. Switch to the soapbox user:
su - soapbox
Checking out the code¶
Use git to download the latest stable release of Soapbox Legacy:
git clone https://gitlab.com/soapbox-pub/soapbox.git live && cd live
Installing the last dependencies¶
bundle install \ -j$(getconf _NPROCESSORS_ONLN) \ --deployment --without development test yarn install --pure-lockfile
Generating a configuration¶
Run the interactive setup wizard:
RAILS_ENV=production bundle exec rake gabsocial:setup
- 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 documentation on configuration.
You're done with the soapbox user for now, so switch back to root:
Setting up nginx¶
Copy the configuration template for nginx from the Soapbox Legacy directory:
cp /home/soapbox/live/dist/nginx.conf /etc/nginx/sites-available/soapbox ln -s /etc/nginx/sites-available/soapbox /etc/nginx/sites-enabled/soapbox
/etc/nginx/sites-available/soapbox to replace
example.com with your own domain name, and make any other adjustments you might need.
Reload nginx for the changes to take effect:
systemctl reload nginx
Acquiring a SSL certificate¶
We'll use Let's Encrypt to get a free SSL certificate:
certbot --nginx -d example.com
This will obtain the certificate, automatically update
/etc/nginx/sites-available/soapbox to use the new certificate, and reload nginx for the changes to take effect.
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 Soapbox Legacy process yet.
Setting up systemd services¶
Copy the systemd service templates from the Soapbox Legacy directory:
cp /home/soapbox/live/dist/soapbox-*.service /etc/systemd/system/
Then edit the files to make sure the username and paths are correct:
Finally, start and enable the new systemd services:
systemctl start soapbox-web soapbox-sidekiq soapbox-streaming systemctl enable soapbox-*
They will now automatically start at boot time.
Hurray! This is it. You can visit your domain in the browser now!
