Tarkvara paigaldamine
Paigaldamiseks tuleb öelda
# apt-get install openafs-{fileserver,dbserver,client,krb5}
Paigaldamise käigus kompileeritakse sellised tuuma moodul
/lib/modules/2.6.32-5-amd64/updates/dkms/openafs.ko
kusjuures Debian Squeeze puhul kasutatakse DKMS tehnikat

OpenAFS klient
Tarkvara paigaldamine
# apt-get install openafs-client openafs-krb5
Paigaldamisel debconf küsib
- AFS cell nime, vastata nt 'loomaaed'.
- AFS vahelao (ingl. k. cache) suurust, nt 50000 (kB)
Tarkvara seadistamine
Lisada /etc/openafs/CellServDB faili sissekanna oma AFS serveri kohta, nt
>loomaaed #Cell name 192.168.10.206 #afs-server.loomaaed
Käivitamine
# /etc/init.d/openafs-client start Starting AFS services: openafs afsd. afsd: All AFS daemons started.
Tulemusena monteeritaks külge /afs ressurss
# df -h Filesystem Size Used Avail Use% Mounted on ... AFS 8.6G 0 8.6G 0% /afs

Kliendist AFS serveri teenuste kasutamise lõpetamiseks tuleb öelda
# /etc/init.d/openafs-client stop Stopping AFS services: afsd openafs.
Kasutamine
Klientarvutis AFS serveri kasutamiseks tuleb öelda
