[Introduction]

This article provides a quick started guide on how to set up and configure GlusterFS on Amazon Linux. Two EC2 instance are being launched to accomplish this goal. On both EC2 instances, there is an instance-store volume serving as the shared storage.

Edit /etc/hosts on both EC2 instances with the following entries (assuming that the private IP addresses are 172.31.0.11 and 172.31.0.12).

172.31.4.11	gluster01

172.31.4.12	gluster02

Create the a repository definition /etc/yum.repos.d/gluster-epel.repo with the following content:

# Place this file in your /etc/yum.repos.d/ directory



[glusterfs-epel]

name=GlusterFS is a clustered file-system capable of scaling to several petabytes.

baseurl=http://download.gluster.org/pub/gluster/glusterfs/LATEST/EPEL.repo/epel-6/$basearch/

enabled=1

skip_if_unavailable=1

gpgcheck=0



[glusterfs-noarch-epel]

name=GlusterFS is a clustered file-system capable of scaling to several petabytes.

baseurl=http://download.gluster.org/pub/gluster/glusterfs/LATEST/EPEL.repo/epel-6/noarch

enabled=1

skip_if_unavailable=1

gpgcheck=0



[glusterfs-source-epel]

name=GlusterFS is a clustered file-system capable of scaling to several petabytes. - Source

baseurl=http://download.gluster.org/pub/gluster/glusterfs/LATEST/EPEL.repo/epel-6/SRPMS

enabled=0

skip_if_unavailable=1

gpgcheck=0

Use the following commands to install the necessary packages and start services.

sudo yum update

sudo yum install fuse fuse-libs nfs-utils

sudo yum install glusterfs glusterfs-fuse glusterfs-geo-replication glusterfs-server



sudo chkconfig glusterd on

sudo chkconfig glusterfsd on

sudo chkconfig rpcbind on

sudo service glusterd start

sudo service rpcbind start

[Configurations]

On both EC2 instances, create file system on the instance-store volume and mount it to /glusterfs.

sudo mkdir /glusterfs

sudo mkfs.ext4 /dev/xvdb

sudo mount /dev/xvdb /glusterfs

sudo mkdir -p /glusterfs/brick

On gluster01, probe the other EC2 instance and create the GlusterFS volume. The name of the volume is "test-volume".

sudo gluster peer probe gluster02

sudo gluster volume create test-volume replica 2 transport tcp gluster01:/glusterfs/brick gluster02:/glusterfs/brick

sudo gluster volume start test-volume

On both EC2 instance, mount the GlusterFS volume. The name of the volume is "test-volume". Then we change the ownership of the /mnt/glusterfs folder to "ec2-user:ec2-user" so that the default "ec2-user" can use the shared folder directly.

sudo mkdir -p /mnt/glusterfs

sudo mount -t glusterfs gluster01:test-volume /mnt/glusterfs

cd /mnt

sudo chown -R ec2-user:ec2-user glustefs

mount

df -h

Now the shared file system has been set up, and you can create a text file under /mnt/glusterfs and observe that the file created appears on both EC2 instances. Please bear in mind that this is only a quick start guide, and you should not use this configuration directly in a production system without further tunings.
