## 1. Overview
TimechoDB supports registering ConfigNode, DataNode, and AINode as Linux
system services via the three scripts `daemon-confignode.sh`,
`daemon-datanode.sh`, and `daemon-ainode.sh`. Combined with the system-built
`systemctl` command, it manages the TimechoDB cluster in daemon mode, enabling
more convenient startup, shutdown, restart, and auto-start on boot operations,
and improving service stability.
