Openstack official website content: http://docs.openstack.org/grizzly/openstack-object-storage/admin/content/ Because I only focus on the part of openstack Object Storage, I did not write anything related to other modules (or I am relatively lazy). I may add it if necessary in the future. The translation level is limited. If a netizen finds an error during re

For beginners, OpenStack manual deployment is cumbersome and takes more time to learn. But we can use deployment scripts to install OpenStack.Online there is a known as the most stupid OpenStack deployment tool called Devstack. I used to think it was quite a fool. The component is pulled straight down from GitHub, not only slow not to say, Even version compatibil

As a core tutorial for OpenStack, we have come to the final summary. OpenStack currently has dozens of modules, this tutorial discusses the most important core modules: Keystone,nova,glance,cinder and neutron. Please look at the following figure: This figure is truncated from https://www.openstack.org/software/project-navigator/, which is the official 6 Core Service defined by

modules (Nova, Cinder, Glance, Keystone, Horizon, Swift) contributed significantly to the downward trend, and here the emphasis is on proportion rather than quantity, In terms of quantity, the difference between versions is not significant, with Nova as an example, from the Havana version of 24% down to today's 10%. This reflects the growing stability of OpenStack's core modules, with more focus on higher levels or functional optimizations.Neutron module has been in a steady state of Ascension,

OpenStack is an excellent cloud operating system, and it is wise for developers, administrators, and operators to have the skills associated with them in their virtual toolkit. Efficient cloud requires an efficient database and can accept multiple databases. But what if you want IBM? DB2 for OpenStack, what should I do? OpenStack does not support DB2 by default.

OpenStack Object Storage Service (SWIFT) configuration: I added two hard drives (SDB,SDC) to the compute node for storage, and the compute node in my build is the storage node, because the computer can't pull more virtual ...

Well, we've already installed fuel master, and now we're ready to install OpenStack, so you can see the OpenStack main interface when the installation is complete.Continue yesterday, we went into the fuel UI and then "new OpenStack Environment" to create the OpenStack deployment environment.650) this.width=650; "src="

= = Keystone Service = =OpenStack-keystone: inactiveAs shown above: If you start httpd, you will not be able to start the Openstack-keystone service very well, as you can see in the official documentation: the 35357 . By default, the Keystone service still listens on ports35357. Therefore, this guide disables the Keystone Service.This means that the httpd and

Use the screen command to restart the service in OpenStack　　In older versions of OpenStack, it is common to use./rejoin-stack.sh to restart all specified services, in the newest master branch, and no rejoin-stack.sh, then restart the service only first. Unstack.sh, and then./stack.sh. Of course not, this is a very waste of time. In fact, we can manage each of the OpenSt
