Directory Description

You can specify the directory for storing the HAF installation package. This document uses the omm user and the cgroup subdirectory omm_haf as an example. During the installation, select /home/omm/haf-software as the directory for storing the software installation package and /home/omm/haf-install as the software installation directory. After HAF is installed on the host node, the haf-host directory is generated in /home/omm/haf-install. After the HAF service is installed on the offload node, the haf-target directory is generated in /home/omm/haf-install. After the HAF library is installed on the offload node, the haf-offload directory is generated in /home/omm/haf-install.

The HAF installation package contains three software packages: haf-host, haf-target, and haf-tool. After HAF is installed on the host node, all related files are stored in /home/omm/haf-install/haf-host. After the HAF service is installed on the offload node, all related files are stored in /home/omm/haf-install/haf-target. After the HAF library is installed on the offload node, all related files are stored in /home/omm/haf-install/haf-offload. The haf-tool software package is used to run maintenance commands.

Table 1 describes the installation packages and their installation directories.

The /home/omm/haf-software directory created by the user is used only for running the installation package and related installation scripts. The /home/omm/haf-install/haf-host, /home/omm/haf-install/haf-target, and /home/omm/haf-install/haf-offload directories are used for service running.

**Table 1** Directories after the installation
Installation Node	Directory Category	Directory Name	Description
All nodes (host node + offload node)	Directory for storing software packages	/home/omm/haf-software	Stores BoostKit-haf_1.3.0.zip. The haf-1.3.0.tar.gz package extracted from BoostKit-haf_1.3.0.zip contains the software package, tool script package, and installation configuration file required for HAF installation, for example, haf-host-1.3.0.tar.gz, haf-target-1.3.0.tar.gz, and haf-tool-1.3.0.tar.gz.

Planning Installation Nodes

During the deployment, you need to plan a root CA server for issuing authentication certificates to HAF host and offload nodes. If there is only one node, perform all operations on the node.

When issuing certificates by using the root CA server, ensure that the time on each node is synchronized. Otherwise, the certificate verification fails due to the system time difference. You can configure NTP for synchronization.

**Table 2** Installation node planning
Node	Installing HAF	Whether to Generate a Certificate	Function
host1	Yes	Yes	Host node for HAF offload.
target1	Yes	Yes	Offload node for running the remote service. The root certificate server (planned by yourself) is used to issue certificates.
