Express Setup - Red Hat DIRECTORY SERVER 8.1 - INSTALLATION GUIDE 11-01-2010 Installation Manual

Chapter 3. Setting up Red Hat Directory Server on Red Hat Enterprise Linux

3.3. Express Setup

Use express installation if you are installing Directory Server for an evaluation or trial. Because
express installation does not offer the choice of selecting the Directory Server server port number
or the directory suffix, among other settings, Red Hat recommends not using it for production
deployments.
NOTE
The Directory Server requires the fully-qualified domain name to set up the servers, as
described in
uses the system's gethostname() function to obtain the hostname (such as ldap) and
the /etc/resolv.conf file to identify the domain name (such as example.com).
Therefore, if there are aliases in the /etc/hosts file that do not match the specified
domains in the /etc/resolv.conf settings, the setup script cannot correctly generate
the fully-qualified domain name as it is used by DNS, and the default options in the
prompts are wrong.
WARNING
If Directory Server is already installed on your machine, it is extremely important that you
perform a migration, not a fresh installation. Migration is described in

dsktune checks the available disk space, processor type, physical memory, and other system
data and settings such as TCP/IP ports and file descriptor settings. If your system does not meet
these basic Red Hat Directory Server requirements, dsktune returns a warning. dsktune
warnings do not block the setup process; simply enter y to go to the next step.
4. Next, choose the setup type. Enter 1 to perform an express setup.
5. The next step allows you to register your Directory Server with an existing Directory Server
instance, called the Configuration Directory Server. This registers the new instance so it can be
