For this blog, i’ve setup a linux KVM vps, using as distro Fedora 27. Fedora 27 comes with Selinux enforced security policy by default this is OK for system or apps where you required a high security level, but for my case to serve a static blog and run a couple of services like OpenSSH and Nginx is ok to set the security policy on permissive mode.
changing the policy can be done via command or setup in permanent way on the selinux config
in /etc/selinux/config
