Lately I've experienced a very frustraiting problem with my VPS provider which I've been using for almost 7 years. They've shut down all the power and thousands of their clients got left with no way of accessing pre-payed servers. I was forced to restore backups and look for a new hosting company. Unfortunatelly I didn't have backup of system apps and configs. 🐏
I've had CentOs 7 running there. Always liked it for it's stability and figured out it would be a good opportunity to jump on a new major version of CentOs 8 and create a bash script with initial setup of production server.

Creating keypair for Superuser on local PC
rem -------------------------------------------------------
rem Create keypair for Production_VPS
rem -------------------------------------------------------
mkdir %userprofile%\.ssh\keys\production_vps
ssh-keygen -N "" -f %userprofile%\.ssh\keys\production_vps\id_rsa
code %userprofile%\.ssh\keys\production_vps\id_rsa.pub
When keypair is created keep public key close. You'll need to paste it to VPS when prompted to enable Superuser login using ssh keypair.
