At this point, we have to construct a list of the hosts which will run NIS
servers.  centos is in the list of NIS server hosts.  Please continue to add
the names for the other hosts, one per line.  When you are done with the
list, type a <control D>.
        next host to add:  centos
        next host to add:  alicia.net
        next host to add:  alicia
        next host to add:  
The current list of NIS servers looks like this:

centos
alicia.net
alicia

Is this correct?  [y/n: y]  y
We need a few minutes to build the databases...

centos has been set up as a NIS master server.

Now you can run ypinit -s centos on all slave server.
