Chapter 1. Installation options The following table presents the various Red Hat Update Infrastructure 4 components. Table 1.1. Red Hat Update Infrastructure components and functions Component Acronym Function Alternative Red Hat Update Appliance RHUA Downloads content from the Red Hat content delivery network and stores it on the shared storage None Content Delivery Server CDS Provides the yum repositories that clients connect to for the updated packages None HAProxy None Provides load balancing across CDS nodes Existing load balancing solution Shared storage None Provides shared storage Existing storage solution The following table describes how to perform installation tasks. Table 1.2. Red Hat Update Infrastructure installation tasks Installation Task Performed on Install RHEL 8 RHUA, CDS, and HAProxy Register the system with the RHUI consumer type RHUA Register the system with the default consumer type CDS and HAProxy Apply updates RHUA, CDS and HAProxy Install rhui-installer RHUA Run rhui-installer RHUA 1.1. Option 1: Full installation A RHUA with shared storage Two or more CDS nodes with this shared storage One or more HAProxy load-balancers 1.2. Option 2: Installation with an existing storage solution A RHUA with an existing storage solution Two or more CDS nodes with this existing storage solution One or more HAProxy load-balancers 1.3. Option 3: Installation with an existing load-balancer solution A RHUA with shared storage Two or more CDS nodes with this shared storage An existing load-balancer 1.4. Option 4: Installation with existing storage and load-balancer solutions A RHUA with an existing storage solution Two or more CDS nodes with this existing shared storage An existing load-balancer Important Red Hat Update Infrastructure must be used with at least two CDS nodes and a load-balancer node. Installation without any load-balancer node and with a single CDS node is unsupported. The following figure depicts a high-level view of how the various Red Hat Update Infrastructure 4 components interact. Figure 1.1. Red Hat Update Infrastructure 4 overview Install the RHUA and CDS nodes on separate x86_64 servers (bare metal or virtual machines). Ensure all the servers and networks that connect to RHUI can access the Red Hat Subscription Management service.
