```

## Comunic Server
1. Clone the repository
```bash
git clone https://gitlab.com/comunic/comunicapiv3
cd comunicapiv3
```

2. Build the server
```bash
cargo build --release
```

3. Create & edit custom configuration
```bash
cp config.yaml config.private.yaml
chmod 700 config.private.yaml
nano config.private.yaml
```

4. Adapt the following command to test the server: `/home/comunic/comunicapiv3/target/release/comunic_server /home/comunic/comunicapiv3/config.private.yaml`

5. Enable required modules in Apache:
```bash
sudo a2enmod proxy_http
sudo a2enmod proxy_wstunnel
```

6. Create Apache configuration, save it & restart Apache:
```conf
<VirtualHost *:443>
    ServerName api.communiquons.org

    ServerAdmin webmaster@localhost

    ErrorLog ${APACHE_LOG_DIR}/error.log
    CustomLog ${APACHE_LOG_DIR}/access.log combined

    # Redirect user web socket
    RewriteEngine On
    RewriteCond %{REQUEST_URI} (.*)/ws$    [NC]
    RewriteRule /ws ws://localhost:3005/ws [P,L]


    ProxyPreserveHost On
    ProxyRequests off
    AllowEncodedSlashes NoDecode
    ProxyPass / http://localhost:3005/ nocanon
    ProxyPassReverse / http://localhost:3005/

    SSLEngine on
    SSLCertificateFile    /etc/letsencrypt/live/communiquons.org-0001/fullchain.pem
    SSLCertificateKeyFile  /etc/letsencrypt/live/communiquons.org-0001/privkey.pem
</VirtualHost>
```

7. Create systemd configuration (in `/etc/systemd/system/comunic.service`):
```conf

# Modify these two values ​​and uncomment them if you have
# repos with lots of files and get to HTTP error 500 because of that
###
# LimitMEMLOCK=infinity
# LimitNOFILE=65535
RestartSec=2s
Type=simple
User=comunic

Restart=always
Environment=USER=comunic 
HOME=/home/comunic

[Install]
WantedBy=multi-user.target
```
