Three major software load balancer comparisons (LVS, Nginx, HAproxy)(Information from the network, made part of the supplementary instructions)LVS:1. Strong anti-load capability, high performance, can reach F5 60%, low memory and CPU resource consumption2. Work in the Network 4 layer, through the VRRP protocol (for Proxy only), the specific traffic is handled by

LVS Cluster has DR, TUN, Nat three configuration mode, can be the WWW service, FTP services, mail services, such as load balancing, the following through the construction of the WWW service load Balancer instance, describes the DR model based on the LVS cluster configuration.First, the configuration of Director serverThere are two ways to configure the LVS

Introduction to the Basic overviewLVS is a load balancing software that works at the transport level and consists of two components of the IPVSADM and kernel space of the user space Ipvs. The Ipvsadm is a command-line tool for user space, primarily for manag

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

session application server. In this case, the nginx backend can only direct to the application server, or create another squid and then point to the application server. The best way is to use location for one-time traffic distribution. part of the requests that require session are distributed through ip_hash, and the rest are distributed through other backend servers.4) upstream_hashTo solve ip_hash problems, you can use upstream_hash, a third-party module, which is generally used as url_hash,

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

One, load balancing load Balance: built on the existing network structure, it provides an inexpensive and effective way to extend the bandwidth of network devices and servers, increase throughput, enhance network data processing capabilities, and improve network flexibility and availability. This means that it can be shared across multiple operating units, such as Web servers, FTP servers, enterprise critic
