How to Install OpenVPN on a VPS?

OpenVPN is a popular technology used to create a secure connection over the internet. Installing OpenVPN on a VPS allows you to ensure data transmission security and bypass access restrictions to resources on the Web. In this article, we will thoroughly analyze the process of installing OpenVPN on a virtual private server.

Step 1: Connecting to the VPS

The first step is to connect to your VPS via SSH. To do this, open a terminal and enter the command:

ssh user@vps_ip_address

Where «user» is your login, and «vps_ip_address» is the IP address of your virtual server.

Step 2: Installing OpenVPN

To install OpenVPN on your VPS, execute the following commands:

  • sudo apt update
  • sudo apt install openvpn easy-rsa

These commands will update the packages on the server and install the necessary packages for OpenVPN to work.

Step 3: Configuring OpenVPN

After installation, you need to copy the OpenVPN configuration files to the /etc/openvpn/ directory. This can be done with the following command:

sudo cp -r /usr/share/easy-rsa/ /etc/openvpn/

Next, you need to configure the security keys as follows:

cd /etc/openvpn/easy-rsa

./easyrsa init-pki

./easyrsa build-ca

These commands will create an authorization certificate for OpenVPN.

After that, you need to generate server and client certificates:

./easyrsa gen-req server nopass

./easyrsa sign-req server server

./easyrsa gen-req client nopass

./easyrsa sign-req client client

And, finally, create an encryption key:

./easyrsa gen-dh

After executing all the commands, the OpenVPN configuration will be ready for use on your VPS.

Step 4: Starting OpenVPN

To start OpenVPN, enter the following command:

sudo systemctl start openvpn

Now OpenVPN is running and ready to go. You can configure additional parameters in the configuration file /etc/openvpn/server.conf.

Step 5: Client Configuration

To connect a client to your OpenVPN server, you should configure the configuration files on the client side. Create a client.ovpn file and add the necessary settings to it.

After that, you can connect the client to the server using the command:

sudo openvpn --config client.ovpn

Conclusion

Now you have OpenVPN configured on your VPS, which provides a secure connection and protects your data on the Internet. Follow these steps and enjoy security and anonymity online!
