cd /etc/openvpn/easy-rsa/
sudo ./easyrsa init-pki
sudo ./easyrsa build-ca nopass
sudo ./easyrsa gen-dh
sudo ./easyrsa build-server-full server nopass
sudo ./easyrsa build-client-full client1 nopass
# Creating Diffie-Hellman parameter file (with gen-dh command)
sudo ./easyrsa gen-dh
# Copying generated files to OpenVPN directory
sudo cp pki/ca.crt pki/private/ca.key pki/issued/server.crt pki/private/server.key pki/dh.pem /etc/openvpn/
