[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.
