Chapter 2. Installation Requirements

This chapter details the requirements that must be met before installing Red Hat Update Infrastructure on your environment.

2.1. Installation Prerequisites

Cloud Provider Prerequisites

The following are prerequisites to becoming a certified Red Hat Cloud Provider. These must be fulfilled prior to installing and configuring Red Hat Update Infrastructure in a cloud environment.
  • Complete a Cloud Provider Agreement with Red Hat. Cloud providers must be certified by Red Hat in order to be able to resell Red Hat Enterprise Linux.
  • Ensure you have an entitlement for every RHUA instance in the cloud. This grants access to:
    • Red Hat Update Infrastructure (RHUA and associated technologies).
    • 32-bit and 64-bit Red Hat Enterprise Linux images. This is required to perform instantiation.
    • Permission for the RHUA to synchronize channel content from RHN.
  • The ability to generate or obtain CA and SSL certificates. These are required for configuring SSL and signing client entitlement certificates.
  • Employ a method of monitoring that includes some means of notification and the ability to run custom scripts and commands.
Hardware and Storage Requirements

Red Hat Update Infrastructure has the following hardware and storage requirements:

  • Red Hat Enterprise Linux 6.1 or higher. Red Hat Update Infrastructure will not run on Red Hat Enterprise Linux 5 or below.
  • 64-bit architecture. Red Hat Update Infrastructure will not run on 32-bit architecture.
  • At least 2GB of available memory
  • At least 4GB of available swap space
Ensure that you have allocated enough storage space for the RPM packages required by Red Hat Update Infrastructure.
All repositories are placed under /var/lib/pulp. Create this file directly only if you need to create a new mount point for it, otherwise, it will be created automatically during the installation process. You will require at least 30GB of storage for each software channel in /var/lib/pulp
All repositories are synchronized with content distribution server (CDS) nodes under /var/lib/pulp-cds.

Note

If you expect to be storing a large amount of data, consider using a separate storage volume for the installation.
Network and Firewall Requirements

Red Hat Update Infrastructure uses various network protocols for communication between RHUA, CDS, and client instances. The following table outlines each of the protocols used:

Table 2.1. Protocols and Port requirements

Port Protocol Source Destination Notes
443 HTTPS RHUA Package Source Third-party repository such as RHN
443 HTTPS CDS RHUA Allows the CDS to download content from the RHUA
443 HTTPS Client CDS Used by yum on the client to retrieve packages
5674 QPID RHUA CDS Used for communication between the RHUA and the CDS
5674 QPID CDS RHUA Used for communication between the RHUA and the CDS

Note

Every CDS instance must have 443 (HTTPS) as well as 5674 access to the RHUA in order to be able to synchronize packages.
