# b. Configure NFS

The next step is to setup NFS.

On the login node:

Make a directory for everything that we may want to share.
```
mkdir /export
mkdir /export/{apps,data,service,site}
```
Ensure that permissions are correct.
```
chmod 775 -R /export/
```

Go to /etc/exports and add this:

/export/apps 10.50.0.0/16(rw,no_root_squash,sync)
/export/data 10.50.0.0/16(rw,no_root_squash,sync)
/export/service 10.50.0.0/16(rw,no_root_squash,sync)
/export/site 10.50.0.0/16(rw,no_root_squash,sync)
/home 10.50.0.0/16(rw,no_root_squash,sync)

The IP addresses and subnet mask you need to use will be different.

Bind mounts for the NFS server. Open the the file /etc/fstab and add this, then save and close the file.

/export/apps    /opt/apps none defaults,bind 0 0
/export/data    /opt/data none defaults,bind 0 0
/export/service /opt/service none defaults,bind 0 0
/export/site    /opt/site none defaults,bind 0 0

Create several new directories:
```
mkdir /opt/{apps,data,service,site}
```
Start and enable NFS:
```
systemctl start nfs-server.service
systemctl enable nfs-server.service
```
start activates NFS, and enable means that NFS will startup on boot.
Export and show the mount points, then mount them.
```
exportfs -va
mount -a
```
the v option shows more information and the a option exports/mounts all.

The NFS server has now been setup. Follow the instructions on the compute nodes tab to complete setup.

On a compute node:

Open the file /etc/fstab and add the following text, then save and exit.

 chead1:/export/apps    /opt/apps     nfs    rsize=32768,wsize=32768,vers=3,_netdev,nofail    0 0
 chead1:/export/data    /opt/data     nfs    rsize=32768,wsize=32768,vers=3,_netdev,nofail    0 0
 chead1:/export/service /opt/service  nfs    rsize=32768,wsize=32768,vers=3,_netdev,nofail    0 0
 chead1:/export/site    /opt/site     nfs    rsize=32768,wsize=32768,vers=3,_netdev,nofail    0 0
 chead1:/home           /home         nfs    rsize=32768,wsize=32768,vers=3,_netdev,nofail    0 0

Make directories for NFS:
```
 mkdir /opt/{apps,data,service,site}
```

Start NFS

systemctl start nfs-client.target
systemctl enable nfs-client.target 

Mount NFS
```
 mount -a
```

At this point, this node is fully setup to be an NFS client. Repeat these steps on every other compute node, and then NFS will be completely set up.
