Grid & Sim Admin Guide

This guide is for people who run OpenSimulator: installing the runtime, building from source, configuring it, and keeping it running and backed up.

There are two programs you will deal with:

• OpenSim – the simulator that hosts regions and talks to viewers.
• Robust – the grid services server (assets, inventory, grid map, login, …) used in grid mode.

Prerequisites

• .NET 8.0 runtime/SDK – see Installing .NET.
• libgdiplus on Linux/macOS (for image handling).
• A supported OS: Windows 10/11, Linux, or macOS.

Sections

1. Installing .NET
2. Building OpenSim from source
3. Standalone mode – one process, everything local (great for testing).
4. Grid mode – running Robust, or connecting to an existing grid.
5. Advanced INI configuration
6. Console commands & backup

New admins should go in order: install .NET, build, then set up standalone first.
