If you want to set up a Virtual Private Network (VPN) on your Virtual Private Server (VPS), there are a few steps you need to follow. Here is a step-by-step guide to setting up a VPN on your VPS:
There are different VPN protocols to choose from, such as OpenVPN, L2TP, and PPTP. OpenVPN is the most popular and recommended protocol, and we will be using it in this guide.
Install OpenVPN on your VPS using the package manager of your distribution. For example, on Ubuntu, you can use the command "sudo apt-get install openvpn".
Copy the sample configuration file to /etc/openvpn/ using the command "sudo cp /usr/share/doc/openvpn/examples/sample-config-files/server.conf.gz /etc/openvpn/". Then, unzip the file using the command "sudo gunzip /etc/openvpn/server.conf.gz".
Open the configuration file in a text editor using the command "sudo nano /etc/openvpn/server.conf". Edit the file to match your VPS settings, such as the server IP address and port number.
Generate the certificates and keys for OpenVPN using the command "sudo /usr/share/easy-rsa/easyrsa init-pki". Then, build the certificate authority (CA) using the command "sudo /usr/share/easy-rsa/easyrsa build-ca". Finally, generate the server certificate and key using the command "sudo /usr/share/easy-rsa/easyrsa build-server-full server".
Start OpenVPN using the command "sudo systemctl start openvpn@server". Check the status of OpenVPN using the command "sudo systemctl status openvpn@server".
Configure the client to connect to the VPN server by copying the client configuration file from the VPS to the client computer using secure copy (SCP). The client configuration file is located at /etc/openvpn/client.conf.
Setting up a VPN on a VPS may seem daunting, but by following these steps, you can create a secure and private connection to your VPS.
