Oracle VM + centos7.1+openstack kilo Multi-node installation tutorial---Installation of glance

Disclaimer: The recent installation of the kilo version of OpenStack found that there were very few existing web tutorials and that most of the tutorials did not install successfully, So write this tutorial. The installation of OpenStack is complex, and this tutorial does not guarantee that it will be installed successfully in different environments. Personal installation tutorials are also prone to errors. At the same time, the installation is in the virtual machine environment, the real installation environment needs to be changed.
