32 Chapter 4. Silent Installation and Instance Creation
4.1.1. Silent Installation on Red Hat Enterprise Linux
It is possible to use silent instance creation on Red Hat Enterprise Linux servers.
1. Log in as root.
2. Create a new directory:
mkdir ds
cd ds
3. If you have not already done so, download the product binaries file to the installation directory.
4. Install the Directory Server as normal, using the command line
or the Red Hat RPM tool, system-config-packages (refer to
Section 3.4 Installing on Red Hat Enterprise Linux Using a Typical Installation).
5. Prepare the file that contains your installation directives.
Refer to Section 4.1.2 Preparing Silent Installation Files for instructions and for some examples
of the silent-install files.
6. Fill in appropriate values for the installation directives.
Refer to Section 4.1.3 Specifying Silent Installation Directives for the complete list of silent in-
stallation directives that you can use when installing Directory Server.
7. When you run the setup program, specify the .inf file you have created, as follows:
/opt/redhat-ds/servers/setup/silent.inf
4.1.2. Preparing Silent Installation Files
The best way to create a file for use with silent installation is to use the setup program to create
interactively a server instance of the type that you want to duplicate. To do this, run setup with the -k
flag. The setup program creates the following file:
serverRoot/setup/install.inf
This file contains all the directives that you would use with silent installation to create the server
instance. You can then use this file to create other server instances of that type.
You have to make some modifications to this file before you use it. Specifically, ensure that you have
done the following:
• FullMachineName - Set this directive to a value that is appropriate for the machine on which
Directory Server is installed if it is not to be the local machine. In most circumstances, it is best not
to use this directive because FullMachineName then defaults to the local host name. However,
if you use custom installation to generate your initial server instance, then this directive appears in
the install.inf file.
• ServerIpAddress - Set this directive appropriate for the local machine. The same usage rules
apply for ServerIpAddress as for FullMachineName. Specifically, try not to include
ServerIpAddress in your install.inf file unless you absolutely have to (as may be necessary
for multi-homed systems).
• ServerRoot - Verify the installation path on this directive. Also, the name of the file-system
directory where you install files must not contain any space characters.
• ServerIdentifier - If you are installing more than one Directory Server on the same host,
make sure that this directive contains a unique value for each server instance.
