Ubuntu 22.04 LTS Set Up OpenVPN Server In 5 Minutes

Setting up an OpenVPN server on Ubuntu 22.04 LTS is a relatively simple process that can be completed in just a few minutes. Here is a step-by-step guide to help you set up an OpenVPN server on your Ubuntu 22.04 LTS system:

1. First, make sure that your system is up to date by running the following command:

sudo apt update
sudo apt upgrade

2. Install the OpenVPN package by running the following command:

sudo apt install openvpn

3. Generate the necessary SSL/TLS certificates and keys:

sudo apt install easy-rsa
sudo make-cadir /etc/openvpn/easy-rsa
cd /etc/openvpn/easy-rsa

Now you will need to edit the file vars to set the appropriate values for your environment. Open the file with a text editor (e.g. nano) and make the following changes:

• Set KEY_COUNTRY to the two-letter code for your country
• Set KEY_PROVINCE to the name of your state or province
• Set KEY_CITY to the name of your city
• Set KEY_ORG to the name of your organization
• Set KEY_EMAIL to your email address

Once you have made these changes, save the file and run the following command to initialize the PKI (public key infrastructure):

source vars
./clean-all
./build-ca

Follow the prompts to create the certificate authority (CA) certificate and key. Next, generate the server certificate and key:

./build-key-server server
