# Configuring Open OSCAR Server With systemd This document details the configuration of Open OSCAR Server to run as an unprivileged user with `systemd` managing it as a production service. 1. **Download Open OSCAR Server** Grab the latest Linux release from the [releases page](https://github.com/mk6i/open-oscar-server/releases) 2. **Create the ras user and group** Run the following commands: ```shell sudo useradd ras sudo mkdir -p /opt/ras ``` 3. **Extract the archive** Extract the archive using the usual `tar` invocation, and move `open_oscar_server` into `/opt/ras` 4. **Set Ownership and Permissions** ```shell sudo chown -R ras:ras /opt/ras sudo chmod -R o-rx /opt/ras ``` 5. **Copy the systemd service** Place the `ras.service` file in `/etc/systemd/system` 6. **Reload systemd** ```shell sudo systemctl daemon-reload ``` 7. **Enable and start the service** ```shell sudo systemctl enable --now ras.service ``` 8. **Make sure the service is running** ```shell sudo systemctl status ras.service sudo journalctl -xeu ras.service ``` Note that the `systemd` service defines the configuration for Open OSCAR Server directly, bypassing the `settings.env` config. Customizations may be performed in `/etc/systemd/system/ras.service`.
