Heartbeat + LVS build a high-availability server Load balancer Cluster 1. Introduction to heartbeat: The Heartbeat project is an integral part of the Linux-HA project, which implements a high-availability cluster system. Heartbeat service and cluster communication are two key components of a highly available cluster. In the heartbeat project, the Heartbeat module implements these two functions. This cluster

Oracle RAC provides two methods to achieve load balancing. The first is pure technical means, that is, when a user connects, the node that determines based on the current load of the system to process user requests; the second type is business-oriented. Applications are divided into many services manually, and connection requests from a service are processed by a node.Let's take a look at these two methods:

synchronization strategy according to the type of SQL statement to ensure the minimization of the data synchronization cost. 3. Advantages and Disadvantages Advantages:(1) Strong extensibility: When the system to higher database processing speed, as long as simply increase the database server can be extended.(2) Maintainability: When a node fails, the system will automatically detect the failure and transfer the application of the fault node to ensure the continuous work of the database.(3) Sec

Nginx Server Load balancer is an amazing technology that many people cannot master. Here we will introduce the problems related to nginx Server Load balancer in detail. I tried nginx Load Balancing today! What is nginx? Nginx ("engine X") is a high-performance HTTP and rever

: This article mainly introduces the nginx server load balancer configuration. if you are interested in the PHP Tutorial, refer to it. Common load balancing solutions include the following: 1. Round Robin Round Robin (Round Robin) distributes client Web requests to different backend servers in sequence based on the order in the Nginx configuration file. The confi

Practice steps: First: On the local server (10.60.44.126), create a website using the port 808, for example: IIS website binding settings Second: Create a website in the Remote IIS 10.60.44.127 using the port 808, for example: Remote IIS binding settings Note: The first

Apache HTTP Server is selected as the front-end Server Load balancer, and two Tomcat clusters are selected at the backend. The selected configuration method is session sticky (sticky session ), this method forwards requests from the same user to a specific Tomcat server to avoid session replication in the cluster. The disadvantage is that the user only communicates with one server, if the server is down, it

This article describes how to configure Simple Server Load balancer on Docker. The host machine is Ubuntu14.04.2LTS, two CentOS containers, Nginx for the host machine, and tomcat 7 for the two containers. The architecture is as follows: the principle of this solution is to map the host machine port and the docker container port (that is, a port accessing the host machine will be mapped to the corresponding

Since the release of this series, I have received replies from many friends! Thank you very much. At the same time, many friends have asked some questions, some of which are basic questions. 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

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
