4.2. Using Silent Instance Creation
If you have Directory Server installed in a server root, you can create additional instances of Directory
Server under the same server root without having to run the setup program. You can create additional
instances of the server either by using Red Hat Console or from the command-line.
Because all instances of Directory Server under a server root use the same Administration Server,
the instance creation process does not install Administration Server binaries; you cannot create two
instances of Administration Server in one server root.
Having multiple instances in a single server root is useful for testing and for when one host is used
for multiple purposes. Keep in mind that each Directory Server instance must be assigned a different
port number and server identifier.
The
ds_create
program, which is located in the
serverRoot /bin/slapd/admin/bin
directory,
enables you to create additional instances of Directory Server under a server root. You may want to
use this program when you already have Directory Server installed and just want to create additional
instances of the server from the commandline.
To create a new instance of Directory Server, run this command from the
ServerRoot /bin/slapd/admin/bin
directory:
ds_create -f filename
Where
filename
is the silent instance creation file, which must be similar to the file used with the
setup program (refer to Section 4.1.2 Preparing Silent Installation Files ) except that the file must only
contain the following two sections:
• [General]
• [slapd]
These sections do not take the
Components
directive.
Here’s a sample file for instance creation. The
\
is inserted to break the line for printing purposes.
You need to remove the
\
and make that one single line.
