How to Install OpenVPN Server
OpenVPN is a powerful and secure open-source software that allows you to create your own virtual private network (VPN) server. By setting up an OpenVPN server, you can encrypt your internet traffic, access region-restricted websites, and enhance your online privacy and security. In this guide, we will walk you through the process of installing an OpenVPN server on various operating systems.
Prerequisites
- A VPS or dedicated server with root access
- Operating system: Ubuntu 20.04, CentOS 7, or Debian 10
- Basic understanding of the command line interface
Step 1: Update the System
Before installing OpenVPN, it is essential to update the system to ensure that you have the latest packages installed. You can update the system by running the following commands:
sudo apt update && sudo apt upgrade
sudo yum update
Step 2: Install OpenVPN
Next, you need to install OpenVPN on your server. The installation process may vary depending on your operating system. Here are the commands to install OpenVPN on Ubuntu, CentOS, and Debian:
Ubuntu 20.04
sudo apt install openvpn
CentOS 7
sudo yum install epel-release
sudo yum install openvpn
Debian 10
sudo apt-get install openvpn
Step 3: Configure OpenVPN
After installing OpenVPN, you need to configure the server settings. The configuration files are located in the /etc/openvpn directory. You can edit the configuration file using a text editor:
sudo nano /etc/openvpn/server.conf
You can customize the configuration file based on your needs, such as changing the port, protocol, and encryption settings. Once you have configured the server, you can start the OpenVPN service:
sudo systemctl start openvpn@server
sudo systemctl enable openvpn@server
Step 4: Generate Client Certificates
To connect to the OpenVPN server, clients need to have a client certificate and key. You can generate the client certificates using the Easy-RSA tool provided by OpenVPN. First, navigate to the Easy-RSA directory and initialize the PKI:
cd /usr/share/easy-rsa/
sudo ./easyrsa init-pki
Next, you can generate the client certificate and key by running the following commands:
sudo ./easyrsa build-client-full CLIENTNAME nopass
Make sure to replace CLIENTNAME with a unique name for the client. Once the client certificate and key are generated, you can transfer them to the client device securely.
Step 5: Connect to the OpenVPN Server
Finally, you can connect to the OpenVPN server from your client device. You can use the OpenVPN client software to establish a secure connection to the server. In the client configuration file, specify the server IP address, port, protocol, and the path to the client certificate and key.
Once you have configured the client, you can connect to the OpenVPN server by running the following command:
sudo openvpn --config client.conf
That’s it! You have successfully installed and configured an OpenVPN server on your VPS or dedicated server. You can now enjoy secure and private internet access from anywhere in the world.
