WireGuard is a modern VPN protocol that provides a simple, fast, and secure way to establish a virtual private network. Here's how to set up a WireGuard VPN on CentOS 8 and access it via Windows 10/7 and mobile devices:
Step 1: Install WireGuard on CentOS 8
Connect to your CentOS 8 server via SSH.
Install the EPEL repository:
Install WireGuard and its dependencies:
Step 2: Generate WireGuard Keys
Create the public and private keys for the server
Create the public and private keys for each client:
Copy the public keys for each client and add them to the server's configuration file:
Step 3: Configure WireGuard
Create the WireGuard configuration file
Add the following configuration to the file:
Replace SERVER_PRIVATE_KEY with the server's private key, and CLIENT_PUBLIC_KEY with the client's public key.
Save and close the file.
Step 4: Start WireGuard
Start the WireGuard interface
Check the status of the WireGuard interface:
Step 5: Connect to the VPN
