install ceph through vagrant on centos7

This paper is for installing ceph on centos7 through vagrant.

prepare

  • enable epel and install development tools 
    1
    sudo yum install epel-release
sudo yum groupinstall 'Development Tools'     # install development tools, not necessary
  • install virtualbox
1
sudo su
cd /etc/yum.repos.d
wget http://download.virtualbox.org/virtualbox/rpm/rhel/virtualbox.repo

yum install dkms
yum install kernel-devel

yum install VirtualBox-5.1    # install the latest virtualbox

Reference: https://wiki.centos.org/HowTos/Virtualization/VirtualBox

The installer will create the “vboxusers” group and create the necessary kernel modules if the development environment has been correctly configured.

For each “username” that will run VirtualBox:

1
usermod -a -G vboxusers username
  • intall vagrant
1
wget https://releases.hashicorp.com/vagrant/1.8.5/vagrant_1.8.5_x86_64.rpm # please use latest vagrant package
sudo rpm -ivh vagrant_1.8.5_x86_64.rpm

then install the vagrant centos7 box

https://atlas.hashicorp.com/centos/boxes/7

1
vagrant box add --provider virtualbox centos/7

run the ceph installation

I have already create a repo for this process, which is verified on centos7.

please refer to this github repo: vagrant-ceph-deploy
