Setting up Tailscale on CentOS 8

Packages are available for x86 and ARM CPUs, in both 32-bit and 64-bit variants.

1. Add the Tailscale repository and install Tailscale:

   sudo dnf config-manager --add-repo https://pkgs.tailscale.com/stable/centos/8/tailscale.repo
   sudo dnf install tailscale
   

2. Use systemctl to enable and start the service:

   sudo systemctl enable --now tailscaled
   

3. Connect your machine to your Tailscale network and authenticate in your browser:

   sudo tailscale up
   

4. You're connected! You can find your Tailscale IPv4 address by running:

   tailscale ip -4
   

If the device you added is a server or remotely-accessed device, you may want to consider disabling key expiry to prevent the need to periodically re-authenticate.
