Red Hat DIRECTORY SERVER 8.1 - INSTALLATION GUIDE 11-01-2010 Installation Manual page 49

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

1. After the Directory Server packages are installed as described in

3. The dsktune utility runs. Select y to continue with the setup.
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
managed by the Console. If this is the first Directory Server instance set up on your network,
it is not possible to register it with another directory. Select n to set up this Directory Server
as a Configuration Directory Server and move to the next express install step, setting up the
administrator user.
