Build the sqlite variant with make sqlite or the postgres variant with
make postgres. The legacy-networking feature is enabled by default, so the
mxd binary is available.
Start the daemon with
cargo run --bin mxd -- --bind 0.0.0.0:5500 --database mxd.db.
Override MXD_-prefixed environment variables or drop-in .mxd.toml files
to persist defaults; the server merges file and env layers before applying
CLI overrides via ortho-config.
The listener prints mxd listening on … once the Tokio accept loop is
running. Use Ctrl-C (and SIGTERM on Unix) for an orderly shutdown.
