Label: 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

I. what is the course (comprehensive introduction)1.1 . Background of the course OpenStack is an open source project initiated by Rackspace, a global developer, designed to create a cloud-based platform that is easy to deploy, feature rich, and easy to scale. OpenStack attempts to become a data center operating system, the cloud operating system. Since the start of the project,

Shortly after I first came into contact with openstack, I encountered some problems when implementing 3-node deployment by referring to the official documentation, mainly focusing on the compute node. Fortunately, I had more than a decade of O M experience to help me solve the problem one by one. The solution is marked in red. System Environment: centos 6.5 64-bit IP addresses of each node: configured according to the IP addresses in the official do

OpenStack installation and configuration is a bit complicated, especially for beginners, the first time you install OpenStack often encounter a lot of problems.

OpenStack is an open source project designed to provide software for the building and management of public and private clouds. Its community is home to more than a few companies and 1350 developers, both of which use OpenStack as a common front-end for infrastructure as a service (IaaS) resources. The first task of the OpenStack project is to streamline the deplo

The full text includes three parts: The first part Part II Part III In the first part of this series, I covered six requirements for enterprise-level OpenStack. Now, I'll focus on the next two main requirements: open architecture and hybrid cloud compatibility. Let's get started right away.Demand 3-open architecture and reduce vendor lock-inWe've talked about building robust cloud control planes and cloud management systems. One

This article explains that OpenStack uses iptables, chains, and rules to handle networking, which is very similar to other systems. But first, let's look at the structure of Iptables as a prelude to the use of technology in this article. The structure of the iptable Iptable is a user-space application that allows system administrators to configure tables provided by the Linux kernel firewall, iptable specifically IPV4 networks. To set up a Linux fi
