Configurar como esta no arquivo anexo: * ks_osgce_instalar.cfg: Kickstart para instala a OSG-CE

[root@sprace ~]# /etc/init.d/dhcpd start
[root@sprace ~]# /etc/init.d/xinetd restart

Mudando na spgrid temporariamente o DNS

[root@spgrid ~]# vim /var/named/chroot/var/named/80.136.200.in-addr.arpa.zone
                                      2008011501 ; Serial

osg-ce          IN      A       200.136.80.25
[root@spgrid ~]# /etc/init.d/named restart

Ja no terminal da maquina

[root@osg-ce ~]# mkdir /opt/scratch/
[root@osg-ce ~]# ln -s /scratch /opt/scratch/
[root@osg-ce ~]# ln -s /usr/local/opt /opt/
[root@osg-ce ~]# ln -s /usr/local/home /home/
[root@osg-ce ~]# rpm -Uvh ftp://ftp.scientificlinux.org/linux/scientific/4x/i386/misc/RPMS/yum-conf-latest.SL.noarch.rpm; yum -y clean all; yum -y  update yum; yum -y update

---++Configuracao do NIS

[root@osg-ce ~]# yum install ypserv
[root@osg-ce ~]# vim /etc/nsswitch.conf
passwd:     files nis
shadow:     files nis
group:      files nis
protocols:  files nis
services:   files nis
netgroup:   files nis
automount:  files nis
aliases:    files nis
[root@osg-ce ~]# vim /etc/yp.conf
domain grid server 192.168.1.152

[root@osg-ce ~]# vim /etc/xinetd.d/time
        disable         = no
[root@osg-ce ~]# vim /etc/xinetd.d/time-udp
        disable         = no
[root@osg-ce ~]# chkconfig xinetd on
[root@osg-ce ~]# chkconfig ypserv on
[root@osg-ce ~]# chkconfig portmap on
[root@osg-ce ~]# chkconfig yppasswdd on
[root@osg-ce ~]# domainname grid
[root@osg-ce ~]# /usr/lib/yp/ypinit -m
[root@osg-ce ~]# service xinetd start
[root@osg-ce ~]# service portmap start
[root@osg-ce ~]# service ypserv start
[root@osg-ce ~]# service yppasswdd start

Na spgrid

[root@spgrid ~]#  scp /etc/passwd /etc/shadow /etc/group /etc/gshadow root@osg-ce.sprace.org.br:/etc/.

Novamente

[root@osg-ce ~]# cd /var/yp/
[root@osg-ce yp]# make

Verifique se ele esta escutando

[root@osg-ce ~]# rpcinfo -u localhost ypserv

Em outra maquina sem jobs do cluster, teste

[root@node84 ~]# vim /etc/yp.conf
ypserver 192.168.1.152
[root@node84 ~]# /etc/init.d/ypbind restart
[root@node84 ~]# rpcinfo -u localhost ypbind
[root@node84 ~]# ypcat passwd
