How to Set Up WireGuard VPN on Amazon Linux 2

by

setting up a WireGuard VPN on Amazon Linux 2 requires several steps. Here is an overview of the process:

  1. Install the WireGuard package:
sudo amazon-linux-extras install wireguard
  1. Enable the WireGuard kernel module:
sudo modprobe wireguard
  1. Create a new WireGuard interface:
sudo ip link add dev wg0 type wireguard
  1. Assign IP addresses to the interface:
sudo ip address add dev wg0 10.0.0.1/24
  1. Enable the interface:
sudo ip link set up dev wg0
  1. Create a WireGuard configuration file:
sudo nano /etc/wireguard/wg0.conf
  1. Insert the following contents in the file:
[Interface]
Address = 10.0.0.1/24
ListenPort = 51820
PrivateKey = <your private key>[Peer]
PublicKey = <peer’s public key>
AllowedIPs = 10.0.0.2/32
Endpoint = <peer’s endpoint>

  1. Generate a private and public key for the server and the client, you can use wg genkey to generate private key and wg pubkey to generate public key.
  2. Start the WireGuard service:
sudo systemctl start wg-quick@wg0
  1. Enable the WireGuard service to start automatically at boot time:
sudo systemctl enable wg-quick@wg0
  1. Configure the firewall to allow WireGuard traffic, you can use iptables for that.
  2. Repeat the same steps on the client side, and you should be able to connect to the VPN.

It’s recommended to use a more secure method of key exchange and also to use a more robust firewall. Also please note that this is just a basic process of setting up WireGuard on Amazon Linux 2, in order to use it in production environment you should consider security and performance configurations.
