The following describes a procedure to set up NIS network name service under Red Hat Linux. This is geared toward a small intallation with only one domain. However, it should be fairly evident how to add more NIS domains. The NIS domain name has nothing to do with any DNS naming convention being used.
 
−
 
 
−
In these examples, the following conventions are used:
 
−
;NIS domain: "internal"
 
−
;Code or configuration file data: colored
 
−
;Root prompt on NIS master server: master#
 
−
;Root prompt on NIS client host: client#
 
−
===Setting up a NIS master server===
 
−
 
 
−
Required packages: yp-tools ypbind ypserv portmap
 
−
 
 
−
Set up "time" service to run via inetd/xinetd, or configure xntpd, or otherwise make sure the host's clock is synchronized.

Edição atual tal como às 22h22min de 27 de junho de 2017

É necessário informar um nome de domínio NIS (que pode ser diferente do domínio DNS matrix). Foi informado nismatrix

Servidor NIS

  • Setar o serviço time para rodar via inetd/xinetd, ou configure xntpd, ou de outro modo certifique-se que o relógio do host esteja sincronizado.
  • Instale o servidor NIS
[one]# dnf install yp-tools
[one]# dnf install ypbind
[one]# dnf install ypserv
[one]# dnf install rpcbind       # já instalado no NFS
  • Edite /etc/yp.conf:
#domain internal server IP_DO_SERVIDOR
domain nismatrix server 192.168.0.100    # ou localhost
  • Edite /etc/ypserv.conf:
..
dns: no
files: 30
xfr_check_port: yes
* : * : shadow.byname : port
* : * : passwd.adjunct.byname : port
  • Edite /etc/sysconfig/network:
NISDOMAIN="nismatrix"
  • Setar o nome do domínio NIS:
[one]# domainname   nismatrix
[one]# ypdomainname nismatrix
  • Crie o arquivo /var/yp/securenets:
host 127.0.0.1
255.255.255.0   192.168.0.0
  • Certifique-se que o serviço rpcbind está rodando
[one]# systemclt start  rpcbind
[one]# chkconfig rpcbind on
  • Editar linhas em
[one]$ vi /var/yp/Makefile
..
ALIASES     = $(YPSRCDIR)/aliases  # aliases could be in /etc or /etc/mail
#ALIASES    = /etc/mail/aliases


  • Inicie o serviço ypserv:
[one]# service ypserv start
  • Verifique se está escutando
[one]# rpcinfo -u localhost ypserv
program 100004 version 1 ready and waiting
program 100004 version 2 ready and waiting
  • Inicialize o mapeamento NIS (especifique one.matrix, Ctrl-D, y, e deixe finalizar):
[one]$ /usr/lib64/yp/ypinit -m

 # one has been set up as a NIS master server.
 # Now you can run ypinit -s one on all slave server.


  • Inicie ypbind, yppasswdd, ypxfrd:
[one]# systemctl start ypbind
[one]# systemctl start yppasswdd
[one]# systemctl start ypxfrd
  • Configure os serviços YP para iniciar no boot:
[one]# systemctl enable ypserv
[one]# systemctl enable ypbind
[one]# systemctl enable yppasswdd
[one]# systemctl enable ypxfrd

Cliente NIS (usando DRBL)

  • Verificar que estejam instalado os pacotes: yp-tools ypbind rpcbind (antigamente portmap)
  • Edite /etc/sysconfig/network:
NISDOMAIN=nismatrix
  • Edite /etc/yp.conf:
domain nismatrix server 192.168.0.99
#domain nismatrix server localhost  #Hmmm... (localhost ou ip)
  • Edite /etc/hosts:
192.168.0.99  one.matrix  one
  • Setar o nome do domínio NIS:
[cell100]# domainname   nismatrix
[cell100]# ypdomainname nismatrix
  • Editar /etc/nsswitch.conf:
..
passwd:     files nis
shadow:     files nis
group:      files nis
..
  • Verifique que o serviço rpcbind está rodando:
[cell100]# service   rpcbind start
[cell100]# chkconfig rpcbind on
    • The /etc/hosts.allow file will need rules allowing access from localhost and the NIS master server.
  • Inicie o serviço ypbind:
[cell100]# service   ypbind start
[cell100]# chkconfig ypbind on
  • Teste:
[cell100]# rpcinfo -u localhost ypbind
[cell100]# ypcat passwd

Gerenciando usuários

Tarefas para o root realizar no servidor NIS

Adicionar usuário
Use uma das opções 
[one]# useradd -g docente usuario
 ou
[one]# useradd -m -g docente -p password usuario   # cria o diretório home

onde grupo=docente (foi necessário usar -p password para que funcionasse)

Atualizar o banco de dados NIS
[one]# make -C /var/yp
Trocar a senha do usuário
[one]# yppasswd -p usuario

Usuários trocaram a senha usando o comando yppasswd ao invés de passwd que afeta o arquivo local. Quando usando um escravo NIS, não modifique a senha enquanto logado no servidor NIS (why?).
