The SoftEther VPN server installation is fairly well documented at http://www.softether.org. The download file for x64 is http://www.softether-download.com/files/softether/v4.18-9570-rtm-2015.07.26-tree/Linux/SoftEther_VPN_Client/64bit_-_Intel_x64_or_AMD64/softether-vpnclient-v4.18-9570-rtm-2015.07.26-linux-x64-64bit.tar.gz
What isn’t document is how to start the service under CentOS, which uses the new systemd files for services instead of the init.d scripts that SoftEther is expecting.
- Create a file in /etc/systemd/system named vpnserver.service. This should be owned by root, have attributes 644 and contain:
# This file is part of systemd.
sudo systemctl enable vpnserver
systemctl start vpnserver systemctl status vpnserver # optional, just to verify
