firstly lets create the user "prometheus" by using below command

# sudo useradd --no-create-home --shell /bin/false prometheus

lets create required prometheus directories by using below commands

# sudo mkdir /etc/prometheus
# sudo mkdir /var/lib/prometheus



lets make the created user the owner of the created directories


# sudo chown prometheus:prometheus /etc/prometheus
# sudo chown prometheus:prometheus /var/lib/prometheus
