Run StatLite as a systemd service

install.sh is the user-level installer: it installs only the StatLite binary, normally in ~/.local/bin. It does not create configuration, users, data directories, or services. Use scripts/systemd.sh to provision a server-wide systemd service on a Linux host by downloading its release-tagged copy.

The script must run as root. It downloads GitHub Release assets directly, verifies their SHA-256 checksums, and keeps release logic in this repository so a pinned release never fetches mutable installer code from main.

Install

Choose the StatLite release to install:

STATLITE_VERSION=v0.1.0

Download the provisioning script from the same release tag:

curl -fsSL \
  "https://raw.githubusercontent.com/PVRLabs/statlite/${STATLITE_VERSION}/scripts/systemd.sh" \
  -o statlite-systemd.sh

Review the downloaded script, then run it with a complete StatLite configuration:

sudo sh statlite-systemd.sh install \
  --version "${STATLITE_VERSION}" \
  --config ./statlite.yaml

Pinning both the script and --version ensures the provisioning logic and StatLite binary come from the same release.

When running from a repository checkout, the equivalent command is:

sudo ./scripts/systemd.sh install \
  --version "${STATLITE_VERSION}" \
  --config ./statlite.yaml

--config is the caller-supplied source file to copy. It is not referenced in place. --config-path is the managed destination the service reads.

Setting Default
Service user/group statlite
Binary /usr/local/bin/statlite
Config destination /etc/statlite/config.yaml
Data/working directory /var/lib/statlite
Unit /etc/systemd/system/statlite.service
Version latest release

The default statlite system user and group are created automatically. Existing custom users/groups are reused without unrelated account changes. A missing custom user or group requires --create-user.

sudo sh statlite-systemd.sh install \
  --version "${STATLITE_VERSION}" \
  --user finrecord \
  --group finrecord \
  --binary-path /home/finrecord/.local/bin/statlite \
  --config ./generated/statlite.yaml \
  --config-path /etc/finrecord/statlite.yaml \
  --data-dir /var/lib/finrecord/statlite \
  --service-name finrecord-statlite \
  --no-start

This supports external provisioners such as FinRecord while keeping their configuration generation outside this generic script. --no-start still enables the service, but does not start it.

Configuration is root:<service-group> and 0640. Its managed directory is root:<service-group> and 0750; the data directory is <service-user>:<service-group> and 0750. The unit uses the data directory as its working directory, so relative SQLite paths resolve there.

Safe reruns and unit reconciliation

Rerunning install is safe when layout and configuration match. It refreshes the binary and keeps the service enabled. It never silently replaces a different configuration, migrates paths, or overwrites local unit edits.

The generated unit records a management marker and layout metadata. If the layout matches but the unit has local changes, explicitly replace only the unit:

sudo sh statlite-systemd.sh install --config ./statlite.yaml --reconcile-unit

Layout conflicts must be resolved by an operator; the script does not migrate an installation implicitly. Reconciliation never changes configuration or data.

Upgrade

Upgrades discover existing paths, account, and group from the managed unit:

sudo sh statlite-systemd.sh upgrade
sudo sh statlite-systemd.sh upgrade --version 1.2.3
sudo sh statlite-systemd.sh upgrade --no-restart

The new binary is downloaded, checksum-verified, and version-checked before it replaces the current binary. The former binary is retained as <binary-path>.previous for manual recovery. Configuration, data, and the unit are unchanged by default. Use --reconcile-unit to intentionally refresh a customized managed unit. It reloads systemd and restarts unless --no-restart is also supplied.

For manual recovery, stop the service, move <binary-path>.previous back to <binary-path>, then start it. Automatic rollback is not performed.

Verify and troubleshoot

systemctl status statlite.service --no-pager
journalctl -u statlite.service -n 50 --no-pager
/usr/local/bin/statlite --version

If service startup fails, the script prints this status and the last 50 journal entries, then exits nonzero. Check configuration syntax and permissions, SQLite path access, and target network access.
