Install and Configure Syncthing on AlmaLinux 9

This guide intends to teach you to Install and Configure Syncthing on AlmaLinux 9. Syncthing is an open-source file synchronization tool. It allows users to securely and efficiently sync files and directories across multiple devices or nodes. Also, it provides a decentralized and peer-to-peer approach to file synchronization. It means that there is no central server involved in the process.

In this guide, we try to teach you to set up Syncthing on AlmaLinux 9 and access it through the web interface.

Learn To Install and Configure Syncthing on AlmaLinux 9

Before you start your Syncthing setup, you must access your server as a non-root user with sudo privileges and set up a basic firewall. To do this, you can check the AlmaLinux 9 Initial Setup Guide.

Then, follow the steps below to complete this guide.

Step 1 – Download and Install the Latest Syncthing on AlmaLinux 9

First, you must run the system update with the following command:

sudo dnf update -y

Then, you must visit the GitHub Release Page For Syncthing and use the following command to download the latest source code package:

curl -s | grep browser_download_url | grep linux-amd64 | cut -d '"' -f 4 | wget -qi -

Once your download is completed, extract it by using the command below:

sudo tar xvf syncthing-linux-amd64*.tar.gz

Next, copy your Syncthing binary files to the /usr/bin directory:

 sudo cp syncthing-linux-amd64-*/syncthing /usr/bin/

At this point, you can verify your Syncthing installation on AlmaLinux 9 by checking its version:

syncthing  --version
syncthing v1.27.3 "Gold Grasshopper" (go1.21.6 linux-amd64) [email protected] 2024-01-15 03:45:19 UTC

Step 2 – Manage Syncthing Service with Systemd on AlmaLinux 9

At this point, you can create a systemd unit file to manage your Syncthing service via systemd. First, you must create a user for Syncthing and add it to the wheel group. To do this, you can use the commands below:

# sudo useradd -m syncthing
# sudo usermod -aG wheel syncthing

Then, set a password for your Syncthing user:

sudo passwd syncthing

Now you can use your desired text editor like Vi Editor or Nano Editor to create your Syncthing systemd unit file on AlmaLinux 9:

sudo vi /etc/systemd/system/[email protected]

Add the following content to the file:

Description=Syncthing - Open Source Continuous File Synchronization for %I

ExecStart=/usr/bin/syncthing serve --no-browser --no-restart --logflags=0
SuccessExitStatus=3 4
RestartForceExitStatus=3 4

# Hardening

# Elevated permissions to sync ownership (disabled by default),
# see
#AmbientCapabilities=CAP_CHOWN CAP_FOWNER


Note: To allow listening on all interfaces, you can use the following ExecStart line:

ExecStart=/usr/bin/syncthing --no-browser --gui-address="" --no-restart --logflags=0

Once you are done, save and close the file.

Next, reload the systemd service to apply the changes:

sudo systemctl daemon-reload

You can start and enable your Syncthing service on AlmaLinux 9 by using the commands below. Remember to specify your Syncthing user:

# sudo systemctl start syncthing@syncthing
# sudo systemctl enable syncthing@syncthing

Verify your service is active and running:

sudo systemctl status syncthing@syncthing
Start and Enable Syncthing service on AlmaLinux 9

Step 3 – Configure Firewall Rules For Syncthing

At this point, we assumed that you have a running FirewallD. Now you must allow the following ports through your AlmaLinux 9 firewall:

sudo firewall-cmd --add-port={8384,22000}/tcp --zone=public --permanent

Reload the firewall to apply the new rules:

sudo firewall-cmd --reload

Step 4 – Access Syncthing via Web Interface

Now you can access your Syncthing web UI by typing your server’s IP address in your web browser followed by 8384:


Once you access your Syncthing Web UI, you will see a warning message to set a GUI Authentication User and Password in the Settings dialog. Click on Settings.
