Mifos installation on vps

I have a fresh Ubuntu box waiting for a clean, production-ready Nginx installation that will host my Mifos instance. The task is straightforward but needs to be done right: install the latest stable Nginx, apply any tweaks required for Mifos to run smoothly, and hand back a server that can be rebooted at any time without losing its configuration.

Here is what I expect to walk away with:
• Nginx installed from the official or PPA source you recommend
• A dedicated server block (virtual host) configured for my domain and pointing to the Mifos web root
• Basic hardening—firewall rule, SSL via Let’s Encrypt, sensible security headers
• A short README outlining every command you ran and the location of any custom files you touched

I’ll supply root SSH credentials as soon as we agree on the start time. Once the site loads over HTTPS and survives a restart, the job is done.
