Let me preface this by saying I'm pretty clueless with it comes to VPNs, so if you need any further info just ask - I'm not purposely being vague I just have no clue.
So I want to install OpenVPN onto a CentOS6 server. I've followed this guide: https://www.digitalocean.com/community/tutorials/how-to-setup-and-configure-an-openvpn-server-on-centos-6
All the certificates have successfully generated, however when I come to start OpenVPN, I get the following:
service openvpn start Starting openvpn: [FAILED]
Where should I be looking to remedy this? I've hit a brick wall.
