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.

|
||
sudo pip3 install commentjson beautifulsoup4 pycryptodome
|

```
|
||
|
||
## Installation
|
||
|
||
In the most common case you'll be using systemd to set up a daemon to run the server.
|
||
|
||
Add a dedicated user so that we don't have to run as root.
|
||
|
||
``` bash
|
||
adduser --system --home=/etc/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=/etc/epicyon
|
||
ExecStart=/usr/bin/python3 /etc/epicyon/epicyon.py --port 443 --proxy 7156 --domain YOUR_DOMAIN --registration open --debug
|
||
Environment=USER=epicyon
|
||
Restart=always
|
||
StandardError=syslog
|
||
|
||
[Install]
|
||
WantedBy=multi-user.target
|
||
```
|
||
|
||
Here the server was installed to */etc/epicyon*, but you can change that to wherever you installed it.
|
||
|
||
Then run the daemon:
|
||
|
||
``` bash
|
||
systemctl enable epicyon
|
||
chown -R epicyon:epicyon /etc/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;
|
||

|
||

|
||

||

|
||
limit_req zone=req_limit_per_ip burst=10 nodelay;
|
||
|
||
index index.html;
|
||
rewrite ^ https://$server_name$request_uri? permanent;
|
||
}
|
||
|
||

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
|
||
```
|
||
|
||
## 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
|
||
```
