Installing the packages

We'll be using the packages provided by CentOS. To install GlusterFS, we first install the repository as follows:

yum install -y centos-release-gluster41

Then, we install the glusterfs-server package:

yum install -y glusterfs-server

We then make sure the glusterd service is enabled and started:

These commands need to be run on each of the nodes that will be part of the cluster; this is because each node requires the packages and services to be enabled.
