Installing The Certificate System Packages; Installing Through Yum - Red Hat CERTIFICATE SYSTEM 8 Install Manual

3.2. Installing the Certificate System Packages

There are two ways to obtain and install the subsystem packages. For all supported platforms, the
Certificate System packages can be downloaded as ISO images through the appropriate Red Hat
Network channel. These packages are then installed through a package utility, such as rpm.
Alternatively, if the appropriate network access is available, the subsystems and dependencies can be
downloaded and installed on Red Hat Enterprise Linux systems using the yum command.
Several packages are installed with the Certificate System packages for related applications and
dependencies, not only for the subsystems. These packages are listed in

NOTE
When the first subsystem is installed on a machine, the installation process automatically
creates a new user (pkiuser) and group (pkiuser). All default Certificate System
instances run as this user and group.

3.2.1. Installing through yum

NOTE
pkicreate is launched by the installer to create the default instances, using default
settings. There is an environment variable, DONT_RUN_PKICREATE, which stops the
pkicreate script from running automatically after the subsystems are installed.
Setting DONT_RUN_PKICREATE allows the default instances to be installed in user-
defined installation directories, instead of the default locations in /var/lib. It can be
preferable to install through the ISO image with this environment variable set to block
the pkicreate script for deployments where the default instances must be installed in
custom locations.
NOTE
To use an IPv6 hostname for configuration, set the hostname in the PKI_HOSTNAME
environment variable before installing the packages. This is described in
