Additional instances of the Directory Server can be created from the command line using the setup-ds-admin.pl command. This offers the setup choices (express, typical, and custom) that are described in Chapter 3, Setting up Red Hat Directory Server on Red Hat Enterprise Linux.

It is also possible to provide Directory Server parameters on the command line, so that the instance is created with pre-defined defaults. For example:

setup-ds-admin.pl slapd.ServerPort=1100 slapd.RootDNPwd=secret

When the installer runs, the Directory Server port default is 1100, and the Directory Manager password is secret.

This script can also be run in silent mode, which means the setup program never opens; the Directory Server instance values are taken from a specified file. For example:

setup-ds-admin.pl -s -f file.inf

-s runs the script in silent mode, and -f file.inf specifies the setup file to use. Silent instance setup and .inf files are described in Section 4.5, “Silent Setup”.

The setup-ds.pl command creates an instance of Directory Server without installing the Admin Server or Directory Server Console (so it is not managed by the Directory Server Console). It works exactly the same way as setup-ds-admin.pl, except that the questions about the Configuration Directory Server and Admin Server are omitted. Using this command to create a Directory Server instance means that the instance has to be managed through the command line or other tools, or it can be registered with the Configuration Directory Server to manage it with the Console. See Section 4.3.2, “Registering an Existing Directory Server Instance with the Configuration Directory Server” for more information.
