OpenStack two or three things (1)

Update series is not a textbook, not didactic, unreasonable, only record.

OpenStack is hot in cloud computing, and there's no reason not to know about it. Let's talk about my feeling about OpenStack, open source, cheap, hassle, everyone is using, after understanding the development process, OpenStack has a complete development process, from requirements to testing, can be in control, this is our dream of software process management method, although there will be unsatisfactory place, But it is admirable to do what most companies do not do with an open-source, loosely organized structure.

To understand, install a test first, the installation procedure is very simple, but the installation process is not easy.

Using the CentOS 7 version and VirtualBox, the installation uses the all in VM Guide to find the Devstack document address on the OpenStack website in just a few steps. Git can sometimes download, with other tools to download, note that the SH and py files are set to +x, otherwise you will see invalid permissions issues.

If there is no successful installation, then each time you rerun stack.sh the previous download and installation of the part will be faster than the past, this is still better, or cry to death.

The Run an unstack.sh and then the clean up/delete your ~/.config/openstack/clouds.yaml file checks the local.conf settings in the set, which can be commented out first, Use the default????
