Creating Subdomain Replicas

The same principles that apply to root domain replicas apply to subdomain replicas (see "Creating a Root Replica Server").

You use the same procedure to create a subdomain replica as you do to create a root replica. The major difference between creating the root replica and a subdomain replica is that the machine you are going to convert to a subdomain replica remains a client of the domain above the one it serves as a replica. This example shows you only what you type to create a replica for the new domain. For the rest of the script's output, see "How to Create a Root Replica".

Prerequisites to Running nisserver

Before you can run nisserver to create a replica:

• The domain must have already been configured and its master server must be running.

• The domain's tables must be populated. (At a minimum, the hosts table must have an entry for the new client machine.)

• You must have initialized the client machine in the parent domain.

• You must have started rpc.nisd on the client.

• You must be logged in as root on the master server. In this example, the master machine is named client2.

Information You Need

• The domain name

• The client machine name (client3, in this example)

• The superuser password for the root master server

How to Create a Replica

Run the nisserver -R command as superuser (root) on the NIS+ domain's master server.

client2# nisserver -R -d sales.doc.com. -h client3
This script sets up a NIS+ replica server for domain sales.doc.com.
Domain name 	::sales.doc.com.
NIS+ server :client
Is this information correct? (type 'y' to accept, 'n' to change)

In this example, client2 is the master server. The -R option indicates that a replica should be configured. The -d option specifies the NIS+ domain name (sales.doc.com. in this example). The -h option specifies the client machine (client3, in this example) that will become the replica. Notice that this machine is still a client of the doc.com. domain and not a client of the sales.doc.com. domain.
