Epicyon is a modern [ActivityPub](https://www.w3.org/TR/activitypub) compliant server implementing both S2S and C2S protocols and sutable for installation on single board computers. It includes features such as moderation tools, post expiry, content warnings, image descriptions and perimeter defense against adversaries.

|
||
|
||
## Installation
|
||
|
||
In the most common case you'll be using systemd to set up a daemon to run the server.
|
||
|
||
The following instructions install Epicyon to the **/etc** directory. It's not essential that it be installed there, and it could be in any other preferred directory.
|
||
|
||
Add a dedicated user so that we don't have to run as root.
|
||
|
||
``` bash
|
||
adduser --system --home=/opt/epicyon --group epicyon
|
||
```
|
||
|
||
Edit */etc/systemd/system/epicyon.service* and add the following:
|
||
|
||
``` systemd
|
||
[Unit]
|
||
Description=epicyon
|
||
After=syslog.target
|
||
After=network.target
|
||
|
||
[Service]
|
||
Type=simple
|
||
User=epicyon
|
||
Group=epicyon
|
||
WorkingDirectory=/opt/epicyon
|
||
ExecStart=/usr/bin/python3 /opt/epicyon/epicyon.py --port 443 --proxy 7156 --domain YOUR_DOMAIN --registration open
|
||
Environment=USER=epicyon
|
||
Environment=PYTHONUNBUFFERED=true
|
||
Restart=always
|
||
StandardError=syslog
|
||
|
||
[Install]
|
||
WantedBy=multi-user.target
|
||
```
|
||
|
||
Here the server was installed to */opt/epicyon*, but you can change that to wherever you installed it.
|
||
|
||
Then run the daemon:
|
||
|
||
``` bash
|
||
systemctl enable epicyon
|
||
chown -R epicyon:epicyon /opt/epicyon
|
||
systemctl start epicyon
|
||
```
|
||
|
||
Check the status of the daemon with:
|
||
|
||
``` bash
|
||
systemctl status epicyon
|
||
```
|
||
|
||
If it's not running then you can also look at the log:
|
||
|
||
``` bash
|
||
journalctl -u epicyon
|
||
```
|
||
|
||
You'll also need to set up a web server configuration. For Nginx edit */etc/nginx/sites-available/YOUR_DOMAIN* as follows:
|
||
|
||
``` nginx
|
||
server {
|
||
listen 80;
|
||
listen [::]:80;
|
||
server_name YOUR_DOMAIN;
|
||
access_log /dev/null;
|
||
error_log /dev/null;
|
||
client_max_body_size 31m;
|
||
client_body_buffer_size 128k;
|
||
|
||
index index.html;
|
||
rewrite ^ https://$server_name$request_uri? permanent;
|
||
}
|
||
|
||

|
||
listen 443 ssl;

Changing your domain name as appropriate. Activate the configuration with:
|
||
|
||
``` bash
|
||
ln -s /etc/nginx/sites-available/YOUR_DOMAIN /etc/nginx/sites-enabled/
|
||
```
|
||
|
||
Generate a LetsEncrypt certificate.
|
||
|
||
``` bash
|
||
certbot certonly -n --server https://acme-v01.api.letsencrypt.org/directory --standalone -d YOUR_DOMAIN --renew-by-default --agree-tos --email YOUR_EMAIL
|
||
```
|
||
|
||
And restart the web server:
|
||
|
||
``` bash
|
||
systemctl restart nginx
|
||
```
|
||
|
||
If you are using the [Caddy web server](https://caddyserver.com) then see *caddy.example.conf*

||
|
||
## Running Static Analysis
|
||
|
||
Static analysis can be run with:
|
||
|
||
``` bash
|
||
./static_analysis
|
||
```
|
||
|
||
## Installing on Onion or i2p domains
|
||
|
||
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.
|
||
|
||
|
||
## Custom Fonts
|
||
|
||
If you want to use a particular font then copy it into the *fonts* directory, rename it as *custom.ttf/woff/woff2/otf* and then restart the epicyon daemon.
|
||
|
||
``` bash
|
||
systemctl restart epicyon
|
||
```
|
||
|
||
## Custom Favicon
|
||
|
||
If you want to use your own favicon then copy your `favicon.ico` file to the base directory where you installed Epicyon.
|
||
|
||
|
||
## Adding Themes
|
||
|
||
If you want to add a new theme then open `theme.py` and add the theme name to the list within `getThemesList`. Add a function with the name `setTheme[YourThemeName]`. Have a look at the other themes to get an idea of how to set the colors and fonts.
|
||
|
||
Add the name of your theme to the translations files.
|
||
|
||
Within the `img` directory add a default profile background image called `image_[YourThemeName].png` and a banner image `banner_[YourThemeName].png`. Because the banner image will be reloaded occasionally it should be small - preferably kilobytes rather than megabytes.
|
||
|
||
On a running instance you can experiment with colors or fonts by editing `epicyon.css` and then reloading the web page. Once you are happy with the results then you can update the changed values within your `setTheme` function.
|
||
|
||
|
||
## Running Unit Tests
|
||
|
||
To run the unit tests:
|
||
|
||
``` bash
|
||
python3 epicyon.py --tests
|
||
```
|
||
|
||
To run the network tests. These simulate instances exchanging messages.
|
||
|
||
``` bash
|
||
python3 epicyon.py --testsnetwork
|
||
```
