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

: 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.

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

This article tries to explain the operation steps and simple configuration of using keepalived + Nginx + Tomcat to build a high-availability load balancing environment in Ubuntu Server environment, which does not involve performance tuning. Let's talk about their respective roles: tomcat– Application Server nginx– reverse proxy server, as a load balancer
