Securely configuring a Linux server for web hosting involves hardening SSH access, enforcing a deny-by-default firewall, configuring Nginx as a static-site server or reverse proxy, and obtaining HTTPS certificates via an ACME client like Let's Encrypt.

The best way to set up an Nginx reverse proxy with HTTPS is to configure the proxy directives for your backend application and then automate certificate issuance using an ACME client after DNS and HTTP validation succeed.

Yes, the SSH hardening and firewall setup processes are distro-aware, meaning they detect the Linux distribution and adapt package names, service units, and commands to ensure compatibility across various environments.

You should verify SSH key-based login before hardening your cloud server by testing your connection; this secure access sequence prevents lockouts by ensuring key authentication works before applying restrictive configurations.

Your firewall blocks web traffic after setting up Nginx because a deny-by-default policy is enforced, requiring you to explicitly open controlled ports for HTTP and HTTPS traffic before external access is permitted.

You need Let's Encrypt or similar ACME client certificates for your Nginx web hosting setup to enable HTTPS, automating the certificate issuance process only after DNS and HTTP validation are successfully completed.
