There comes a time when you're working on multiple servers or nodes that need the same files or resources to function. You can upload everything you need to each instance, but that doesn't scale well if you have hundreds or thousands to manage!
Setting up a network file system share will allow you to stage all of the necessary resources in a central location for your servers to use. No more having to upload resources to individual nodes.
For this demo, I'll use a Fedora server and a Debian client.
IP Addresses to remember:
Fedora Server - 192.168.232.131
Debian Client - 192.168.232.130
- Install nfs-util
dnf install nfs-utils -y
2. Allow NFS to go through the firewall. (I'm using firewalld)
firewall-cmd --add-service=nfs --permanent
3. Reload the firewalld for the settings to take effect.
4. Verify firewalld settings for NFS.
You should see NFS in the list of services:
[scleft@fedora-server]# firewall-cmd --list-all FedoraServer (active) target: default icmp-block-inversion: no interfaces: ens33 sources: services: ssh dhcpv6-client cockpit nfs ports: protocols: masquerade: no forward-ports: source-ports: icmp-blocks: rich rules:
5. Enable and Start NFS
systemctl enable nfs && systemctl start nfs
6. Create a directory on the server to be shared to the clients.
mkdir /var/myshare chmod -R 755 /var/myshare
7. Allow our debian client to connect to the share using's IP address.
Your file should look something like this:
8. Restart NFS server
systemctl restart nfs-server
Now lets connect to the debian client and configure it to connect to the NFS share.
9. Install NFS common
apt install nfs-common -y
10. Create a directory that will used as the NFS mount point.
11. Mount the share.
mount -t nfs 192.168.232.131:/var/myshare /var/myshare
12. Verify it's there!
When you do df you should see something similar on the bottom.
scleft@debian-client:/# df Filesystem Size Used Avail Use% Mounted on udev 478M 0 478M 0% /dev tmpfs 98M 4.4M 94M 5% /run /dev/mapper/debian--vg-root 4.9G 920M 3.7G 20% / tmpfs 490M 0 490M 0% /dev/shm tmpfs 5.0M 0 5.0M 0% /run/lock tmpfs 490M 0 490M 0% /sys/fs/cgroup /dev/mapper/debian--vg-tmp 399M 2.3M 372M 1% /tmp /dev/sda1 236M 63M 162M 28% /boot /dev/mapper/debian--vg-var 2.0G 201M 1.6G 11% /var /dev/mapper/debian--vg-home 17G 45M 16G 1% /home tmpfs 98M 0 98M 0% /run/user/1000 192.168.232.131:/var/myshare 15G 2.2G 13G 15% /var/myshare
13. Test it!
Connect back to the fedora server and create a test file. If you see the same test file on your debian client then you can safely say, it's working!
14. Make the mount permanent.
This mount will disappear when the client reboots, to make it permanent; edit the fstab file.
Add the following lines.
192.168.232.131:/var/myshare /var/myshare nfs rw,async,hard,intr,noexec 0 0
