sudo useradd -s /sbin/nologin --system -g prometheus prometheus

The designated group receives a new user.

Step 4 - Create directory

The Prometheus has its own system for storing things. However, the directory is used to store the data.

Execute the subsequent command to create the directory:

sudo mkdir /etc/prometheus

It is Prometheus's main directory. It will, however, contain a few subdirectories. Run the command listed below to establish a subdirectory:
