Node Exporter Setup on Linux Nodes

Run the following commands on each linux node to install Node Exporter as service.

Procedure

1. Download and move the node exporter binary to /usr/local/bin (You can find the latest binaries from official github link for node_Exporter)

   wget https://github.com/prometheus/node_exporter/releases/download/v*/node_exporter-*.*-amd64.tar.gz
   tar xvfz node_exporter-*.*-amd64.tar.gz
   sudo mv node_exporter-*.*-amd64/node_exporter /usr/local/bin/

2. Create a node_exporter user to run the node exporter service.

   sudo useradd -rs /bin/false node_exporter

3. Create a node_exporter service file under systemd.

   sudo tee /etc/systemd/system/node_exporter.service<<EOF
   [Unit]
   Description=Node Exporter
   After=network.target
    
   [Service]
   User=node_exporter
   Group=node_exporter
   Type=simple
   ExecStart=/usr/local/bin/node_exporter
    
   [Install]
   WantedBy=multi-user.target
   EOF

4. Reload the system daemon and start the node exporter service.

   sudo systemctl daemon-reload
   sudo systemctl start node_exporter
   sudo systemctl enable node_exporter

5. Check the status of node exporter if it is running in active state.
