In today’s guide I’ll walk you through the installation of Quipucords / QPC on CentOS 8 or RHEL 8 Linux server. Quipucords is a tool created to help with the discovery, inspection, collection, deduplication, and reporting of systems in your IT environment. qpc is the RPM command line tool for quipucords. Discovery and inspection of the remote systems is done through Ansible.

Quipucords collects basic information about the operating system, hardware, and application data for each system. The data collected is to help System Administrators simplify some of the basic tasks that are a part of the larger goal of managing licensing renewals and new deployments. For RHEL systems, it helps customers accurately determine how much Red Hat software they are consuming in order to aid in the subscription procurement process.

How QPC works?

QPC is configured with one or more network ranges and SSH credentials, and the server automatically discovers and “fingerprints” systems against supported products. If you have VMware vCenter servers and Red Hat Satellite servers, QPC will connect to them using APIs to reconcile information from these supported management engines.

The QPC Results are written to the local file system in two files and tarballed up for easy sharing. There are two types of reports:

  • Raw data collected – Allows users to see everything that QPC checked.
  • Summary Report – Already analyzed. It combines data from all sources to report a consolidated inventory

Quipucords / QPC Requirements and Assumptions

Minimum Hardware Requirements:

  • CPU: 2 CPU cores / 4 better
  • RAM: 1GB / 2GB better if you have more memory
  • Disk Space: 30 GB

Notes:

  • quipucords is written to run on RHEL or Centos servers.
  • The system that quipucords is installed on must have access to the systems to be discovered and inspected.
  • The target systems must be running SSH.
  • The user account that quipucords uses for the SSH connection into the target systems must have adequate permissions to run commands and read certain files, such as privilege escalation required for the systemctl command.
  • The user account that quipucords uses for a machine requires an sh shell or a similar shell. For example, the shell cannot be a /sbin/nologin or /bin/false shell.

Step 3: Install QPC server and Client on CentOS 8 | RHEL 8

The qpc-tools package is used to install and configure the Quipucords server and command line
interface (CLI) client.

Use the following command to install server package.

sudo qpc-tools server install

It uses Ansible to do the installation and configuration. Just set the password for server and database and wait for the installation to complete.

$ sudo qpc-tools server install

Enter server password:
Enter database password:
Running the following playbook command:
 ansible-playbook /usr/lib/python3.6/site-packages/qpc_tools/server/ansible/install/playbook.yml -vv -e server_port=9443 -e open_port=true -e db_user=postgres -e server_username=admin -e db_password=******* -e server_password=*******
ansible-playbook 2.9.11
  config file = /etc/ansible/ansible.cfg
  configured module search path = ['/root/.ansible/plugins/modules', '/usr/share/ansible/plugins/modules']
  ansible python module location = /usr/lib/python3.6/site-packages/ansible
  executable location = /bin/ansible-playbook
  python version = 3.6.8 (default, Apr 16 2020, 01:36:27) [GCC 8.3.1 20191121 (Red Hat 8.3.1-5)]
Using /etc/ansible/ansible.cfg as config file
......

The username defaults to admin

Here is the extract of my successful installation output:

Installation of server was successful

The server and database services are running as Podman containers:

$ sudo podman ps
CONTAINER ID  IMAGE                              COMMAND               CREATED        STATUS                 PORTS                  NAMES

For QPC client installation use the command:

sudo qpc-tools cli install

Confirm qpc command line tool is available locally.

$ qpc --version
0.9.3

Step 4: Configure QPC Command Line Tool Connection

With the Quipucords server and QPC client installed we need to connect the client to the server. QPC will be installed by default in a container mapped to port 9443.

Configure QPC command line tool by running the command below.

$ qpc server config --host 127.0.0.1 --port 9443
Server config /root/.config/qpc/server.config was not found.
Server connectivity was successfully configured. The server will be contacted via "https" at host "127.0.0.1" with port "9443".

You can now login to QPC server:

$ qpc server login
User name: admin
Password: <Admin-Password>
Login successful.

You can also connect to Quipucords server from a web browser. For this use the URL:

https://[IPaddress]:[port]

Where:

  • [IPaddress] is the IP address of the Quipucords server
  • [port] is the exposed server port, default 9443

Provide the username and password.

Hit the Login button to access Quipucords Dashboard.

We now have Quipucords Server and QPC client installed on CentOS 8 | RHEL 8 Linux systems. Our next article will discuss on usage of QPC.
