Sharing files with NFSv4 on Fedora (Server -> Multi)

Applicable to Fedora Versions

• Fedora Core 6+
  

Requirements

Doing the Work

Configuring the server:

1. Open up the necessary port on the firewall (port: 2049). Activate the "Security Level and Firewall" tool. Optionally, if you want to be able to query portmap, open up port: 111:tcp/portmapper:tcp. You will be asked for your root password. Please enter it:

su -c "system-config-securitylevel"

2. Activate "NFS4" and click "OK".
3. Edit /etc/idmapd.conf. Enter your root password when prompted:

su -c "gedit /etc/idmapd.conf"

4. Configure your domain name and change the users to nfsnobody:

[General]
Domain = example.com

[Mapping]
Nobody-User = nfsnobody
Nobody-Group = nfsnobody

5. Start the portmap and nfslock services, then start the nfs service. Alternatively, you can use System->Administration->Services or System->Administration->Server Settings->Services GUIs. Please enter the root password when prompted:
   

   su -c "/sbin/service portmap start"
   su -c "/sbin/service nfslock start"
   su -c "/sbin/service nfs start"

6. Set portmap, nfslock, and nfs services to start on boot.Alternatively, you can use System->Administration->Services or System->Administration->Server Settings->Services GUIs. Please enter the root password when prompted:

   su -c "/sbin/chkconfig --level 345 portmap on"
   su -c "/sbin/chkconfig --level 345 nfslock on"
   su -c "/sbin/chkconfig --level 345 nfs on"

7. Create the dirs of the exports inside "/nfs4exports". Enter your root password when prompted:

su -c "mkdir -p /nfs4exports/{share1,share2,share3}"

8. Edit /etc/fstab:

su -c "gedit /etc/fstab"

9. Bind the desired shares to the, recently created, dirs at /nfs4exports:

   /path/to/share1		/nfs4exports/share1	none	bind	0 0
   /path/to/share2		/nfs4exports/share2	none	bind	0 0
   /path/to/share3		/nfs4exports/share3	none	bind	0 0

   
   
10. Remount everything. Enter your root password when prompted:

su -c "mount -a"

11. Edit /etc/exports. Enter your root password when prompted:

su -c "gedit /etc/exports"

12. Add your shares here (available to your home network) If you want your shares to be read only, change "rw" to "ro" from these statements:

/nfs4exports			192.168.1.0/255.255.255.0(rw,insecure,no_subtree_check,nohide,fsid=0)
/nfs4exports/share1		192.168.1.0/255.255.255.0(rw,insecure,no_subtree_check,nohide)
/nfs4exports/share2             192.168.1.0/255.255.255.0(rw,insecure,no_subtree_check,nohide)
/nfs4exports/share3             192.168.1.0/255.255.255.0(rw,insecure,no_subtree_check,nohide)

13. Reload your exports. Please enter your root password when prompted:

su -c "exportfs -rv"

14. Edit your /etc/hosts.allow file, so your clients are allowed to access your nfs. Please enter your root password when prompted:
    

su -c "gedit /etc/hosts.allow"

15. Allow your LAN to access your services:

ALL: 192.168.1.0/255.255.255.0

16. Reboot:

su -c "/sbin/shutdown -r now"

Configuring the clients:

1. Edit /etc/idmapd.conf. Enter your root password when prompted:

su -c "gedit /etc/idmapd.conf"

2. Configure your domain name and change the users to nfsnobody:

[General]
Domain = example.com

[Mapping]
Nobody-User = nfsnobody
Nobody-Group = nfsnobody

3. Edit /etc/fstab. Please enter your root password when prompted:

su -c "gedit /etc/fstab"

4. Create the mounting dirs:

su -c "mkdir /mnt/shares /home/me/share1 /home/he/share2 /home/it/share3"

5. Add the desired shares:

<ip-address-to-server>:/	/mnt/shares	nfs4	rsize=8192,wsize=8192,timeo=14,intr
<ip-address-to-server>:/	/home/me/share1	nfs4	rsize=8192,wsize=8192,timeo=14,intr
<ip-address-to-server>:/	/home/he/share2	nfs4	rsize=8192,wsize=8192,timeo=14,intr
<ip-address-to-server>:/	/home/it/share3	nfs4	rsize=8192,wsize=8192,timeo=14,intr

6. Remount everything:

su -c "mount -a"
