Access Network-Attached Storage (NFS and Samba)

Question 1

What are the steps for NFS Server configuration?

Answer 1

1. Install NFS Packages
   yum install nfs-utils libnfsidmap
2. Enable/Start NFS services
   systemctl enable rpcbind | nfs-server
   systemctl start rpc bind nfs-server rpc-statd
   rpc-idmapd
3. Create NFS share directory and assign permissions
   mkdir /nfsshare
   chmod a+rwx /nfsshare
4. Modify /etc/export file to add new shared
   filesystem
   /nfsshare 192.x.x.x (rw,sync,no_root_squash)
   /nfsshare *(rw,sync,no_root_squash)
5. Export the NFS filesystem
   exportfs -rv

Question 2

What are the steps for NFS client configuration? Bonus: How can you unmount the NFS share?

Answer 2

1. Install NFS Packages
   yum install nfs-utils rpcbind
2. Enable and start rpcbind service
   systemctl enable rpcbind
   systemctl start rpcbind
3. Make sure firewalld or iptables is stopped
   ps -ef | egrep “firewalld|iptables”
4. Show mount from the NFS server
   showmount -e 192.168.1.x
5. Create a mount point
   mkdir /mnt/appnfs
6. Mount NFS Filesystem
   mount 192.168.1.x:/nfsshare /mnt/appnfs
7. Verify Mount
   df -h
8. Bonus: To Unmount
   umount /mnt/nfsshare

Question 3

What protocols are used to share Samba?

Answer 3

SMB, SMB v2, SMB v3, CIFS

Question 4

What are the steps to configure Samba on Linux?

Answer 4

1. Snapshot VM
2. Install Samba Packages
   yum install samba samba-client samba-common
3. Enable Samba To Be Allowed Through Firewall
   firewall-cmd –permanent –zone=public
   –add-service=samba
   firewallcmd –reload
4. Create Samba Share Driectories and Assign permissions (-p option creates parent directory
   mkdir -p /samba/name
   chmod a+rwx /samba/name
   chown -R nobody:nobody /samba/name
5. Also Change the SELinux Security Context for Samba Share Directory (-t option is for type)
   chcon -t samba_share_t /samba/name
6. Modify /etc/samba/smb.conf file to add new shared filesystem
   [global]
   workgroup = WORKGROUP
   netbios name = centos
   security = user
   map to guest = bad user
   dns proxy = no
   [Anonymous]
   path = /samba/name
   browsable = yes
   writable = yes
   guest ok = yes
   guest only = yes
   read only = yes
   [Secure]
   path = /samba/securename
   valid users = user
   guest ok = no
7. Verify Settings
   testparm
8. Enable/Start Samba Services
   systemctl start|enable smb|nmb
9. Mount Samba Share on Linux Client
   yum install cifs-utils samba-client
   mkdir /mnt/share
   mount -t cifs //192.x.x.x/Anonymous /mnt/share
