Here you can learn how to download and install the NordVPN app on RHEL (Red-Hat Enterprise) and CentOS distributions, log in, and connect to our servers using VPN for Linux. You can also find an explanation of various settings.
Downloading the app
1. Download the NordVPN Linux client by opening the terminal, writing the command below, and following any on-screen instructions:
sh <(curl -sSf https://downloads.nordcdn.com/apps/linux/install.sh)
Note: If you do not have a curl package, evidenced by the fact that the above does not work, you can alternatively use this command:sh <(wget -qO - https://downloads.nordcdn.com/apps/linux/install.sh)
Additionally, if you receive the following issue: Whoops! Permission denied accessing /run/nordvpn/nordvpnd.sock, all you need to do is write the following command: sudo usermod -aG nordvpn $USER and then reboot your device.
nordvpn login
