I beg to differ.  Fedora roles versions every 6 months and EOLs a 
version in 2 years.  This means you are constantly upgrading versions of 
important servers.  Where as Centos has a 10yr EOL policy.

I only use Fedora for my notebook and when I REALLY need the current 
version of something (like openSSL 1.1.1 for EDDSA testing).

Get Fedora working.  Work it out, then switch to Centos for production.

Just my 5cent worth.
