sudo mv prometheus-2.38.0.linux-amd64/promtool /usr/local/bin/Step 5: Create Configuration Directory
Create a directory for Prometheus configuration:
sudo mkdir /etc/prometheusMove the configuration file to the configuration directory:
sudo mv prometheus-2.38.0.linux-amd64/prometheus.yml /etc/prometheus/Step 6: Set Permissions
Set the appropriate permissions for the Prometheus files:
sudo chown -R prometheus:prometheus /etc/prometheus
sudo chown prometheus:prometheus /usr/local/bin/prometheus
sudo chown prometheus:prometheus /usr/local/bin/promtoolStep 7: Create a Systemd Service File
