use the management network. A separate storage network should be implemented in the production environment to improve performance and security.You can deploy multiple block storage nodes. Each node requires at least one network interface. Object Storage The optional Object storage node contains the disk object

that with the combination of Hadoop and OpenStack, Hadoop is often thought of as being used for big data processing, and on the other hand, big data storage. When it comes to OpenStack storage, there are Ceph systems in addition to Swift.Ceph is often used as a RBD device to provide block

This blog post mainly builds the keystone component in the openstack architecture, and then it will successively manage glance, Nova, neutron, Horizon, cinder, and virtual machines in openstack. Before deploying the experiment, you must first learn about openstack!What is openstack?

"5 minutes a day with OpenStack" is an OpenStack tutorial, this is the 1th article.This tutorial has the following two features: system-guided OpenStack re-practicing and balancing theory /ol> Why do you write this?The simple answer is: because OpenStack learning is difficult, but if you k

object storage, block storage, or network nodes, these are all necessary in a production environment. If the card does not complete during the installation process, you can skip this step temporarily, as these steps do not need to be completed in chronological order except for the first step. A solution to the previous problem may be found during the subsequent installation. Overall, the deployment of the

After the smooth installation of the deployment of Keystone, the original thought that Swift installation and debugging will be like Keystone general, but the process is full of bumpy, in the combination of some functions in the source code, finally successfully completed the installation of Swift, and experimental upload download files and other functions, The following set up the swift installation process, and the problems encountered in the summary, I hope to meet the same problem of people

balance between. More discussion of system performance and architecture is also being carried out around consistency and availability.2) engineering practices for OpenStack, Swift and CapIn contrast to cap theory, OpenStack's distributed object storage System, swift, satisfies availability and partition tolerance, without guaranteeing consistency (optional), but achieving eventual consistency. Swift if the

= = 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

The entire life cycle of instance from creation to deletion is managed by Nova. In the following sections, we take the different operational scenarios in the instance life cycle as an example to analyze in detail how the different Nova components work together and deepen your understanding of Nova through log analysis.Before we study Nova's operations, let's start by learning one important thing: the OpenStack logs.OpenStack's log records very detaile

power can not solve, this time you spend a bit of cost to solve the problem also understand. The key is at the beginning of construction, we must first explore the road, first prepare the corresponding technical support channels, so that the disease will be touyi.Product InstallationFor the general enterprise, OpenStack does not have a low demand for technical staff, because OpenStack itself is a collectio

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.
