Exercise: NFS server configuration
  • Install NFS server packages on master VM by following the instructions below. 
    apt-get install rpcbind nfs-common nfs-kernel-server
    Create a directory to export: 
    mkdir -p /NFS/home
    Create a new user with home directory in /NFS/home: 
    /usr/sbin/groupadd -g 666 edward
/usr/sbin/useradd -m -s /bin/bash -u 666 -g 666 -d /NFS/home/edward edward
    Copy some files from /etc into directory /NFS/home/edward and give them ownership "edward": 
    cp /etc/hosts /NFS/home/edward
cp /etc/nsswitch.conf /NFS/home/edward
chown edward:edward /NFS/home/edward/*
    Then 
    cp /etc/securetty /NFS/home/edward
    and live it with root ownreship.
    Modify file /etc/exports to include the following entry 
    /NFS/home  n01(rw)
    Make sure host n01 is reachable from master: 
    ping -c 2  n01
    Start rpcbind and all the NFSv3 and NFSv4 related services: 
    systemctl restart rpcbind
systemctl restart rpc-statd
systemctl restart nfs-kernel-server
    Make sure the services are running by executing command rpcinfo: 
    rpcinfo -p
    You should see the following: 
       program vers proto   port  service

    100021    3   udp  40359  nlockmgr
    100021    4   udp  40359  nlockmgr
    100021    1   tcp  37625  nlockmgr
    100021    3   tcp  37625  nlockmgr
    100021    4   tcp  37625  nlockmgr
