This tutorial goes from http://blog.sina.com.cn/u/5692023517 to thank the great God for writing such a detailed tutorial and allowing reprint The purpose of this tutorial: to make it easier for beginners to install arch, a good tutorial can take a lot less detours Tutorials using the software: VMware Workstation 12.5.5,virtualbox 5.1.20- Image: Archlinux-2017.05.01-x86_64.iso Installation environment for BIOS + MBR ：

Configure mono and Jexus under Linux (CentOS 6.7) and deploy ASP. MVC3, 4, 5, and Webapi (cross-platform) 1. First of all, before I write this blog, Having configured mono and Jexus locally and successfully deployed an ASP. NET MVC project, I also rely on the various data found on the Internet to configure the environment and deploy the project, and it has a lot of articles on the Internet, so I think I write or not write it, but want to go,　　I would

1. OverviewIn the previous article, "Architecture Design: Load balancer layer Design (4)--lvs principle" (http://blog.csdn.net/yinwenjie/article/details/46845997), we introduced the working mode of LVS, and the specific work processes of each model. In this article, we'll show you how to install a single LVS node. Compared to the previous article, this piece to mention the installation and configuration is very simple, as long as you understand the principle, practice is calm things.You can use

This module is used to do choreography, in fact, it is very valuable, such as the virtual machine can be implemented by the auto scaling. Cloudman If you want to update the tutorial, Heat will certainly not miss it.how to learn. Simply put: Theory with practice . It is difficult to master it tech

On June 23, April 26, the open-source operating system Ubuntu of Canonical launched version 12.04 today. Ubuntu12.04 is a long-term support version that will provide users with support for up to 5 years. Canonical also proposed the "five screens and one cloud" strategy. The new version of the operating system will provide users with cloud solutions for mobile phones, tablets, Internet TVs, PCs, vehicle systems and other platforms. It is understood tha

These technologies may be open source free, or it may be a commercial charge. This open architecture allows OpenStack

appropriate network devices (physical or virtual).Both type and Mechanisim are too abstract, now let's take a concrete example: Type driver for Vlan,mechansim driver for Linux Bridge, and what we're going to do is create the network vlan100, then: VLAN type driver ensures that vlan100 information is saved to the Neutron database, including the network name, VLAN ID, and so on. Linux Bridge mechanism driver ensures that the Linux brige agent on each node creates a VLAN device with I

For example, in the previous example, if you switch to Cisco's mechanism driver, you will add vlan100 on the specified trunk port of the Cisco physical switch.The mechanism driver discussed in this tutorial will cover Linux bridge, open vswitch and L2 population.The role of ML2 mechanism driver for Linux Bridge and open Vswitch is to configure th

Reading Notes on Linux kernel design and implementation (5)-Main content of system calling: What is the implementation principle of system calling on Linux? A simple implementation of system calling 1. in simple terms, system calls are a bridge between user programs and hardware devices. The user program calls the hardware device as needed. The existence of system calls has the following important meanings:1) The user program uses hardware through sys
