Due to the time, they will not reply to them one by one. If they do not understand, I hope you will learn by yourself! Although this series is not difficult, many of the knowledge is required by default, such as the concept, principle, and Web farm of Server Load

: This article describes how to use Nginx server load balancer to build a high-performance. NETweb application 2. if you are interested in PHP tutorials, refer to it. In this article, we use Nginx server load balancer to build high performance. in NETweb Application 1, we have a preliminary understanding of Nginx. next

Next, this section describes the network architecture and configuration process of the RADWARE project. Radware works in active/standby mode. The corresponding networking methods are divided into single-arm networking, dual-arm networking, and triangular transmission. I. Single-arm networkingThe following networking is called single-arm networking, which is a widely used networking method. This networking mode enables complete master-slave switchover. Generally, the gateway of the server must po

If you have experience in cluster, server load balancer, and dual-machine hot standby, you will be able to answer the question: I am using a mysql database web script written in php. If cluster, server load balancer, and dual-machine hot standby are implemented, is there an all-in-one solution? I mean, what I know now

I know what server load balancer and high concurrency should be used to solve this problem, but I don't know how to do it even though I have no experience in the concept of server load balancer and high concurrency, I searched for nginx to achieve load balancing and high con

In this example, I will configure a cloud service Travelweb, which has two VMs, which together provide HTTP services1. Create the first VM TRAVELWEB01, specify the cloud service name as Travelweb when you create it, add an HTTP endpoint2. Create a second VM TRAVELWEB02, using the existing cloud service TravelwebAt this point, both VMs are under the same cloud service and TRAVELWEB02 cannot use public ports 80 and 223. Modify the TRAVELWEB01 endpoint to create a

The previous article written the Nginx load balancer, this article realizes the high Availability (HA). The overall design of the system is to use Nginx to do load balancing, if there is an nginx single-machine failure, the whole system will not function properly. For the high-availability requirements of system architecture design, we need to solve the requireme
