You will need python version 3.7 or later.
On a Debian based system:
sudo apt install -y tor python3-socks imagemagick python3-setuptools python3-cryptography python3-dateutil python3-idna python3-requests python3-flake8 python3-django-timezone-field python3-pyqrcode python3-png python3-bandit libimage-exiftool-perl certbot nginx wget
The following instructions install Epicyon to the /opt directory. It's not essential that it be installed there, and it could be in any other preferred directory.
Clone the repo, or if you downloaded the tarball then extract it into the /opt directory.
cd /opt
git clone --depth 1 https://gitlab.com/bashrc2/epicyon
Create a user for the server to run as:
sudo su
adduser --system --home=/opt/epicyon --group epicyon
chown -R epicyon:epicyon /opt/epicyon
Link news mirrors:
mkdir /var/www/YOUR_DOMAIN
mkdir -p /opt/epicyon/accounts/newsmirror
ln -s /opt/epicyon/accounts/newsmirror /var/www/YOUR_DOMAIN/newsmirror
Create a daemon:
nano /etc/systemd/system/epicyon.service
Paste the following:

Enable the site:
ln -s /etc/nginx/sites-available/YOUR_DOMAIN /etc/nginx/sites-enabled/
Forward port 443 from your internet router to your server. If you have dynamic DNS make sure its configured. Add a TLS certificate:
systemctl stop nginx
certbot certonly -n --server https://acme-v02.api.letsencrypt.org/directory --standalone -d YOUR_DOMAIN --renew-by-default --agree-tos --email YOUR_EMAIL
systemctl start nginx
Restart your web server:
systemctl restart nginx
If you are using the Caddy web server then see caddy.example.conf
Now you can navigate to your domain and register an account. The first account becomes the administrator.
If you don't have access to the clearnet, or prefer not to use it, then it's possible to run an Epicyon instance easily from your laptop. There are scripts within the deploy directory which can be used to install an instance on a Debian or Arch/Parabola operating system. With some modification of package names they could be also used with other distros.
Please be aware that such installations will not federate with ordinary fediverse instances on the clearnet, unless those instances have been specially modified to do so. But onion instances will federate with other onion instances and i2p instances with other i2p instances.
