How To Install yp-tools on CentOS 7
Introduction
In this tutorial we learn how to install yp-tools on CentOS 7.
What is yp-tools
The Network Information Service (NIS) is a system which provides network information (login names, passwords, home directories, group information) to all of the machines on a network. NIS can enable users to login on any machine on the network, as long as the machine has the NIS client programs running and the user’s password is recorded in the NIS passwd database. NIS was formerly known as Sun Yellow Pages (YP). This package’s NIS implementation is based on FreeBSD’s YP and is a special port for glibc 2.x and libc versions 5.4.21 and later. This package only provides the NIS client programs. In order to use the clients, you’ll need to already have an NIS server running on your network. An NIS server is provided in the ypserv package. Install the yp-tools package if you need NIS client programs for machines on your network. You will also need to install the ypbind package on every machine running NIS client programs. If you need an NIS server, you’ll need to install the ypserv package on one machine on the network.
