Configuring Ceph client

Any regular Linux host (RHEL or Debian-based) can act as a Ceph client. The client interacts with the Ceph storage cluster over the network to store or retrieve user data. Ceph RBD support has been added to the Linux mainline kernel, starting with 2.6.34 and later versions.

How to do it...

As we did earlier, we will set up a Ceph client machine using Vagrant and VirtualBox. We will use the same Vagrantfile that we cloned in the last chapter. Vagrant will then launch a CentOS 7.3 virtual machine that we will configure as a Ceph client:

1. From the directory where we cloned the Ceph-Cookbook-Second-Edition GitHub repository, launch the client virtual machine using Vagrant:

         $ vagrant status client-node1
         $ vagrant up client-node1

2. Log in to client-node1 and update the node:

      $ vagrant ssh client-node1
      $ sudo yum update -y     

Note

The username and password that Vagrant uses to configure virtual machines is vagrant,  and Vagrant has sudo rights. The default...
