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

Linux Server Load balancer cluster system solution-Linux Enterprise Application-Linux server application information. For details, refer to the following section. 1. Introduction to Linux virtual servers Linux Virtual Server (LVS) is a high-availability Server Load balancer cluster system. The system can provide

: This article mainly introduces several methods for nginx server load balancer to process session sharing. For more information about PHP tutorials, see. 1) use cookie instead of sessionBy changing the session into a cookie, you can avoid some drawbacks of the session. in a previously read J2EE book, it also indicates that the session cannot be used in the cluster system, otherwise, it will be difficult to

: This article describes how to set up static file separation for NginxTomcat server load balancer. if you are interested in PHP tutorials, refer to it. This article mainly explains how to use Nginx as the front-end web server and tomcat as the backend application server. all Internet requests are forwarded from nginx to the intranet tomcat for processing, that is, nginx Reverse proxy requests to tomcat, or

Lvs-nat model: Similar to Dnat, but supports multi-target forwarding, which is multi-objective DnatIt is forwarded by modifying the destination address of the request message to a certain RS rip selected by the scheduling algorithm.Architectural Features:(1) RS should use a private address, that is, RIP should be a private address, each RS gateway must point to the dip(2) The request message and the response message are forwarded through the Director; in high-

For Web application cluster learning, I started from tomcat5.5. Below are some of my practical operations and experiences.

Label: style blog HTTP Io color OS AR for SP The last two lectures are mainly about the nginx environment, which does not involve the development of the real environment. In this example, describe how to configure nginx for the Server Load balancer and WWW server and how to implement it. The following is an actual scenario: One Server Load

Tags: blog HTTP use 2014 C log R server TTServer Load balancer and redundancy are two different technologies that can be used independently, but they can play a powerful role only when combined. Generally, they are both used in combination.Server Load balancer (SLB): distributes traffic to servers. It is also called ro

Nginx ~ Add Server Load balancer for docker containers, nginxdocker As the most popular Server Load balancer and reverse proxy server, Nginx runs on linux. to achieve traffic distribution and load balancing, You need to deploy on IIS of multiple application servers, use some

Considering the shortcomings of LVS and Nginx (because LVS uses synchronous request forwarding policy and Nginx is the asynchronous forwarding policy, combined with the disadvantage of both: as the Load Balancer server nginx and LVS processing the same request, all requests and response traffic will go through the Nginx server, However, when using LVS, only request traffic through the LVS network, the respo

, transfers the request evenly to the different server execution, and the scheduler automatically shields off the server's failure, thereby forming a set of servers into a high-performance, highly available virtual server. The structure of the entire server cluster is transparent to the customer and eliminates the need to modify client and server-side programs. To do this, you need to consider system transparency, scalability, high availability, and manageability at design time.Cluster structure

The server Load balancer of the Oracle RAC server distributes new connection requests to the node with the smallest load based on the number of connection loads of each node in the RAC. When the database is running, the PMON process of each node in RAC updates the connection load of each node to service_register every

Nginx can be used not only as a powerful web server, but also as a reverse proxy server. nginx can also implement dynamic and static page separation according to scheduling rules, server Load balancer can be performed on backend servers in multiple ways, such as round robin, IP hash, URL hash, and weight. Health Check of backend servers is also supported. If there is only one server and the server goes down
