haproxy tutorial

In the MySQL world, Haproxy is often used as a software load balancer. Peter Boros explains how to use the Percona xtradb cluster (PXC) to set it up in a previous message. So it only sends the query to the applicable node. The same method can be used for general master-slave settings to read the load and spread across multiple nodes. However, with MySQL replication, another factor starts to work: replication latency. In this case, the mentioned Percon

HAProxy introduction, haproxySimple Description HAProxy provides high availability, Server Load balancer, and TCP and HTTP application-based proxy. It supports Virtual Hosts and is a free, fast, and reliable solution. HAProxy is especially suitable for websites with extremely high loads, which usually require session persistence or layer-7 processing.

Hide back-end server versionsIn our daily work we use haproxy as a load balancer, because the backend application server is more cumbersome to change, so it is decided to implement it in the load balancer.Only need to frondend or listen or backend, addRspidel ^server:.* rspidel ^x-forwarded-for:.* rspidel ^x-powered-by:.* rspidel ^via:.* rspide L ^x-aspnet-version:*The above use can refer to Rspidel.In addition, if you need to confuse some people t

This is the first choice. The second stage: with the further expansion of network services, then the single-point nginx can not be satisfied, when the use of LVS or commercial array is the first choice, nginx at this time as a LVS or array of nodes to use, The specific

popularity, the capability and quantity of relevant talents have also increased. at this time, no matter whether it is developed to suit the customization of its own products, as for cost reduction, the open-source LVS has become the first choice. at this time, LVS will become the mainstream.The ideal basic architecture is: Array/LVS-Nginx/Haproxy-Squid/Varnish-AppServer.
