What is Gluster File System

GlusterFS (Gluster File System) is an open source Distributed File System that can scale out in building-block fashion to store multiple petabytes of data.

Use Cases

streaming media , content delivery. Scale-out storage systems based on GlusterFS are suitable for unstructured data such as documents, images, audio and video files, and log files.

Prerequisite

• Minimum Three VM,For this demo we deploy it in AWS EC2.
• git on VM's Make sure EC2/VM have git installed To check

 git --version

To install git

  sudo apt install git-all

• Open ports on Security Groups

Security Group For GFS

Tutorial

In this tutorial
Code Repo - github

• I will launching three ubuntu ec2 instance install.
• Install Gluster FS.
• Peer Servers.
• Create Gluster Volume.
• Test the replication.

If you dont know how to launch ec2 , use this link

Step 1

• launching ec2 , am using Ubuntu Server 20.04 LTS . Also make sure you enable Auto-assign Public IP .
• Am naming three servers as MasterNode , GlusterFS-01, GlusterFS-01, easy for understanding.
• Note down public IP for MasterNode , GlusterFS-01, GlusterFS-01

Step 2

• First SSH into GlusterFS-01. Get root privilages to run command

sudo su -

wget https://raw.githubusercontent.com/anuvindhs/How-to-install-GlusterFS/main/install.sh

chmod u+x install.sh

./install.sh

Info	Screenshots
Enter your Server Name
System will Automatically Update Ubuntu
Installing GlusterFS and Dependencies , once installed restart the servers
If you wish to see the installation data

• Do this for GlusterFS-02 and MasterNode

Now you have success fully installed GlusterFS

Peering GlusterFS 🤝🏼

This is really important , we need to configure the hostname for all three servers

On each server type

sudo nano /etc/hosts/

Nodes	/etc/hosts data
MasterNode
GlusterFS-01
GlusterFS-02

MasterNode
52.62.40.54 MasterNode
54.252.253.181 GlusterFS-01
13.236.188.52 GlusterFS-02
GlusterFS-01
127.0.0.1 GlusterFS-01
52.62.40.54 MasterNode
13.236.188.52 GlusterFS-02
GlusterFS-02
52.62.40.54 MasterNode
54.252.253.181 GlusterFS-01
13.236.188.52 GlusterFS-02

make sure you add your public ip

now lets ping all nodes from all servers
ping Masternode
ping GlusterFs-01
ping GlusterFS-02

if all servers pings successfully, we are going to peer the servers now

Go to Masternode

gluster peer probe GlusterFS-01
gluster peer probe GlusterFS-02

Creating Gluster Volume 💽

On Masternode

sudo gluster volume create gv0 replica 3 transport tcp Masternode:/glusterfs glusterfs-01:/glusterfs glusterfs-02:/glusterfs force

sudo gluster volume start gv0

Congratulations 🎉 you have successfully configured the GlusterFS

Testing Gluster-FS replication

lets check the gluster volume info

Create folder for replication test 📁

sudo mkdir -p /myfiles

Mount the /GlusterFS to /myfiles Folder

sudo mount -t glusterfs Masternode:/glusterfs /myfiles
cd /myfiles
sudo touch file_{0..9}.test
ls /glusterfs

You will be able to see the replicated files on each server
