Installation

First, download the script on your Linux server*:

wget -O openvpn.sh https://get.vpnsetup.net/ovpn

* A cloud server, virtual private server (VPS) or dedicated server.

Option 1: Auto install OpenVPN using default options.

sudo bash openvpn.sh --auto

Note: This recording is for demo purposes only.

For servers with an external firewall (e.g. EC2/GCE), open UDP port 1194 for the VPN.

Option 2: Interactive install using custom options.

sudo bash openvpn.sh

You can customize the following options: VPN server's DNS name, protocol (TCP/UDP) and port, DNS server for VPN clients and name of the first client.

For servers with an external firewall, open your selected TCP or UDP port for the VPN.

You may also use curl to download:

curl -fL -o openvpn.sh https://get.vpnsetup.net/ovpn

Then follow the instructions above to install.

If you are unable to download, open openvpn-install.sh, then click the Raw button on the right. Press Ctrl/Cmd+A to select all, Ctrl/Cmd+C to copy, then paste into your favorite editor.

Advanced users can auto install OpenVPN using custom options, by specifying command-line options when running the script. For more details, see the next section "view usage information for the OpenVPN script".

Alternatively, you may provide a Bash "here document" as input to the setup script. This method can also be used to provide input to manage users after install.

First, install OpenVPN interactively using custom options, and write down all your inputs to the script.

sudo bash openvpn.sh

If you need to remove OpenVPN, run the script again and select the appropriate option.

Next, create the custom install command using your inputs. Example:

sudo bash openvpn.sh <<ANSWERS

1194
