Prometheus Setup

1. Download

sudo yum update -y && sudo yum install -y wget
wget https://github.com/prometheus/prometheus/releases/download/v2.52.0/prometheus-2.52.0.linux-amd64.tar.gz

sudo mv prometheus-2.52.0.linux-amd64/prometheus /usr/local/bin/
sudo mv prometheus-2.52.0.linux-amd64/promtool /usr/local/bin/

1. Make config dir

sudo mkdir /etc/prometheus
sudo mkdir /var/lib/prometheus
sudo cp prometheus-2.52.0.linux-amd64/prometheus.yml /etc/prometheus/

1. Configure Prometheus for node exporter

   sudo nano /etc/prometheus/prometheus.yml
   

   ```yaml scrape_configs:

   • job_name: “node” static_configs:
   • targets: [“localhost:9100”] ```
2. Add Prometheus user

   sudo useradd --no-create-home --shell /bin/false prometheus
   sudo chown -R prometheus:prometheus /etc/prometheus
   sudo chown -R prometheus:prometheus /var/lib/prometheus
   sudo chown -R $(whoami):$(whoami) /var/lib/prometheus

   prometheus \
     --config.file=/etc/prometheus/prometheus.yml \
     --storage.tsdb.path=/var/lib/prometheus
