I am preparing the server for installation in the data center, what may be needed?

Question

linux

Hello . I put the server in the data center so far I have installed only Linux and SSH, what else might be needed? What else needs to be done? Tell me please, since I worked very little with Linux and there is no experience in installing it in the data center. The server will just store the files that will be downloaded, that is, without php . Only nginx will be needed. The site itself is located on another server. So I really need advice on what else needs to be installed and what needs to be configured. Thanks in advance to everyone for your help.

Answer 1

Yes, in general, nothing special.
If you suddenly need to connect to a server at the hardware level, any normal data center provides the KVM-IP service.
There, at least put a new OS from scratch.

Answer 2

Network, ssh-agent for keyed access, deny ssh by password, ntp, firewall, ideally selinux. Further, depending on the needs. At the end of the configuration, set nmap on the server and see what you have extra open.
Given that you have file storage, read about openstack swift, seph. Maybe it will be more useful for you to deploy something from this.
