Installation af master server

Tilføj følgende linje til /etc/hosts.allow.

portmap ypserv ypbind: 10.0.0.0/255.255.255.0

Installer NIS. Du vil blive bedt om at indtaste domænenavnet. Domænenavnet er ikke DNS-domænenavn - men et unikt navn for klyngen af maskiner deler de samme oplysninger.

apt-get install portmap nis
  • Ret /etc/default/nis og set NISSERVER linjen to NISSERVER = master
  • Ret /etc/yp.conf og tilføj en linje med:
domain dka.local server 127.0.0.1
  • Ret /etc/ypserv.securenets fjern 0.0.0.0 linjen - insecure - og tilføj dit eget net(255.255.255.0 10.0.0.0).
  • genstart så yellowpages servicen for at loade det nye configuration.
service ypserv restart

Adding a user

Efter du har oprettet en ny bruger, adduser er det nødvendigt at genopbygge nis maps!

root@head:~# <input>make -C /var/yp</input>
make: Går til katalog '/var/yp'
make[1]: Går til katalog '/var/yp/c1.local'
Updating passwd.byname...
Updating passwd.byuid...
Updating netid.byname...
Updating shadow.byname...
make[1]: Forlader katalog '/var/yp/c1.local'
make: Forlader katalog '/var/yp'

Script adding user in a Cluster

The following simple script:

  • Add a user on the NIS server.
  • Add a ssh key to the users /home library.
    • In this cluster /home is distributed with NFS to all nodes. Logon to nodes without entering password
  • Rebuilding the NIS database with the new user
#!/bin/bash
echo -e "Adding user to cluster"
echo -e "======================\n"
echo -en "User login name: "
read NAME
adduser $NAME

echo -e "Creating keys"
su $NAME -c "ssh-keygen -t dsa"
echo -e "Distributing keys"
su $NAME -c "cat /home/$NAME/.ssh/id_dsa.pub >> /home/$NAME/.ssh/authorized_keys"
echo -e "Rebuild NIS database"
make -C /var/yp

Installation på klienten

Installer software

sudo apt-get install portmap nis

Kør disse kommandoer, hvor NIS_SERVER_IP = din nis server ip

echo "portmap : <notice>NIS_SERVER_IP</notice> >> /etc/hosts.allow
echo "+::::::" >> /etc/passwd
echo "+:::" >> /etc/group
echo "+::::::::" >> /etc/shadow
echo "ypserver <notice>NIS_SERVER_IP</notice> >> /etc/yp.conf
service ypbind restart
