Install Linux Node
The Linux node install script is served by Dash:
https://dash.example.com/deploy/linux/install.sh
The script downloads Dash's bundled node_linux_<arch>, configures push reporting, and registers a systemd service. The node host does not need to download GitHub Release binaries separately.
The script requires root/sudo, systemd, and curl or wget. When LVM/LVM-thin is detected, it installs and enables cron for thinpool collection; Debian/Ubuntu systems that use apt-get do not need cron installed manually first.
Install Command
curl -fsSL https://dash.example.com/deploy/linux/install.sh -o install_node.sh
sudo bash install_node.sh dash.example.com 443 '<node-secret>'
Full form:
sudo bash install_node.sh <dash_ip> [dash_port] <secret> [interval_seconds] [--net iface1,iface2] [--require-https]
If only <dash_ip> <secret> are provided, the port is inferred from the rendered DOWNLOAD_SCHEME: HTTPS uses 443, HTTP uses 80.
Installed Files
| Path | Content |
|---|---|
/var/lib/ithiltir-node/releases/<version>/ithiltir-node | Current node binary |
/var/lib/ithiltir-node/current | Symlink to the current release |
/var/lib/ithiltir-node/report.yaml | Report target config |
/etc/systemd/system/ithiltir-node.service | systemd service |
/run/ithiltir-node/thinpool.json | LVM thinpool cache |
/opt/node/collect_thinpool.sh | LVM thinpool collector |
/etc/cron.d/ithiltir-node-thinpool | thinpool collection cron |
The service runs as the ithiltir system user and uses /var/lib/ithiltir-node as its working directory.
systemd Boundary
The Linux service enables:
NoNewPrivileges=truePrivateTmp=trueProtectSystem=strictProtectHome=trueReadWritePaths=/var/lib/ithiltir-node
The node process should only write to its data directory.
LVM Thinpool
When LVM / LVM-thin is detected, the install script enables thinpool cache collection:
cat /run/ithiltir-node/thinpool.json
If the system has no LVM, old cron entries and collector scripts are removed.
Common Commands
systemctl status ithiltir-node.service
journalctl -u ithiltir-node.service -f
systemctl restart ithiltir-node.service
