In today’s guide, I will guide you through the process of installing Quipucords/QPC on CentOS 8 or RHEL 8 Linux server. Quipucords is a tool designed to help you discover, inspect, collect, deduplicate and report on systems in your IT environment. qpc It is the RPM command line tool of quipucords. The discovery and inspection of the remote system is done through Ansible.

Quipucords collects basic information about each system’s operating system, hardware, and application data. The data collected can help system administrators simplify some basic tasks as part of the larger goal of managing license renewals and new deployments. For RHEL systems, it can help customers determine exactly how much Red Hat software they are using to help with the ordering process.

How does QPC work?

QPC is configured with one or more network ranges and SSH credentials, and the server will automatically discover and “fingerprint” the system based on the supported products. If you have a VMware vCenter server and a Red Hat Satellite server, QPC will connect to them using APIs to coordinate information from these supported management engines.

The QPC results are written into the local file system in the form of two files and packaged for easy sharing. There are two types of reports:

  • Collect raw data – Allow users to view all the content checked by QPC.
  • summary report – Has been analyzed. It combines data from all sources to report a consolidated list

Quipucords/QPC requirements and assumptions

Minimum requirements Hardware requirements:

  • CPU: 2 CPU cores/4 better CPUs
  • Memory: If there is more memory, 1GB / 2GB is better
  • Disk space: 30 GB

notes:

  • Quipucords is written to run on RHEL or Centos servers.
  • The system where quipucords is installed must have access to the system to be discovered and checked.
  • The target system must be running SSH.
  • The user account that quipucords uses to SSH to the target system must have sufficient permissions to run commands and read certain files, for example, systemctl command.
  • The user account that quipucords uses for the machine requires a sh shell or similar shell. For example, the shell cannot be /sbin/nologin or /bin/false shell.

Step 3: Install QPC server and client on CentOS 8. RHEL 8

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

Use the following command to install the server package.

sudo qpc-tools server install

It uses Ansible for installation and configuration. Just set the server and database passwords, and then 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

This is an excerpt from the output of a successful installation:

Installation of server was successful

The server and database services run as Podman containers:

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

For QPC client installation, use the following command:

sudo qpc-tools cli install

Confirm that the qpc command line tool is available locally.

$ qpc --version
0.9.3

Step 4: Configure QPC command line tool connection

After installing the Quipucords server and QPC client, we need to connect the client to the server. By default, QPC will be installed in the container mapped to port 9443.

Configure the QPC command line tool by running the following commands.

$ 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 log in to the QPC server:

$ qpc server login
User name: admin
Password: 
Login successful.

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

https://[IPaddress]:[port]

where:

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

Provide username and password.

Click the login button to access the Quipucords dashboard.
