Step 1: Set Up Your Debian 12 Server
Before installing Resilio Sync, you need a Debian 12 server. If you don’t have one yet, follow these steps to create an instance on Shape.Host:
Log in to Shape.Host and go to your Dashboard.
Click “Create” to start setting up a new virtual machine.
Select “Instances” from the menu to configure your server.

Choose a Data Center Location that is closest to your users for faster performance.

Pick a Server Plan that fits your needs, such as Standard or CPU-Optimized.
Choose Debian 12 as your operating system.

Launch the Instance by selecting either SSH keys or a password for authentication. Click Create Instance to complete the process.

Find your instance’s IP address under the Resources section and use it to access your server.

Step 2: Connect to Your Server
Once your Debian 12 server is up and running, connect to it using SSH.
If you’re using Linux/macOS, run:
ssh root@<your_server_ip>
If you’re on Windows, use PuTTY:
Open PuTTY.
Enter your server’s IP address, select SSH, and click Open to connect.
Step 3: Update Your System
Before installing any software, make sure your system is updated. Run the following command:
apt update && apt upgrade -y
This will update all installed packages to their latest versions, ensuring you don’t run into compatibility issues.

Step 4: Install Required Dependencies
To install Resilio Sync, we need to install some essential tools first. Run the command below to install curl, gnupg2, software-properties-common, and gpg:
apt install curl gnupg2 software-properties-common gpg
These tools help in downloading and verifying software packages securely.

Step 5: Install Resilio Sync
Step 5.1: Add Resilio Sync GPG Key
To ensure we are downloading an authentic package, we need to add Resilio Sync’s GPG key:
curl -sL https://linux-packages.resilio.com/resilio-sync/key.asc | gpg --dearmor -o /usr/share/keyrings/resilio-sync-keyring.gpg
Step 5.2: Add the Resilio Sync Repository
Now, we’ll add the official Resilio Sync repository to our system:
echo "deb [arch=amd64 signed-by=/usr/share/keyrings/resilio-sync-keyring.gpg] https://linux-packages.resilio.com/resilio-sync/deb resilio-sync non-free" > /etc/apt/sources.list.d/resilio-sync.list

Step 5.3: Update Package List
apt update
Step 5.4: Install Resilio Sync
apt install resilio-sync

Step 6: Start and Enable Resilio Sync
Once installed, we need to enable and start the Resilio Sync service.
Step 6.1: Enable Resilio Sync to Start at Boot
systemctl enable resilio-sync
Step 6.2: Start Resilio Sync
systemctl start resilio-sync
Step 6.3: Check Service Status
systemctl status resilio-sync
If the service is active and running, you are on the right track!

Step 7: Configure Resilio Sync
Resilio Sync’s settings can be modified through its configuration file. Let’s open it for editing:
nano /etc/resilio-sync/config.json
Update the “webui” section as follows:
"webui" : {
"listen" : "0.0.0.0:8888"
}

Once done, restart the service for the changes to take effect:
systemctl restart resilio-sync
Step 8: Set Up Firewall Rules
To allow access to Resilio Sync’s web interface, you need to open port 8888 on the firewall.
Step 8.1: Install UFW Firewall (If Not Installed)
apt install ufw

Step 8.2: Allow Port 8888 for Resilio Sync
ufw allow 8888/tcp
Step 8.3: Allow SSH Access
To prevent being locked out of your server, allow SSH access:
ufw allow ssh
Step 8.4: Enable UFW
ufw enable

Step 9: Access Resilio Sync Web UI
Now that everything is set up, you can access Resilio Sync’s web interface from your browser.
Open your browser and go to: http://<your_server_ip>:8888

You will see the Resilio Sync Setup Page. Follow the on-screen instructions to configure your sync folders and devices.
