sudo chown prometheus:prometheus /var/lib/prometheus

Step 5: Copy prometheus and promtool files to the bin and change the ownership to prometheus user.

sudo cp prometheus/prometheus /usr/local/bin/

sudo cp prometheus/promtool /usr/local/bin/

sudo chown prometheus:prometheus /usr/local/bin/prometheus

sudo chown prometheus:prometheus /usr/local/bin/promtool
