1. Introduction to haproxyHAProxy 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. HAProxy runs on the current hardware and supports tens of thousands of concurr

The haproxy runs on the current hardware and can support tens of thousands of concurrent connections. and its operating mode makes it easy and safe

demonstrated here.To check whether the connection is correct, we can use ssl-hello-chk to check the connection and its ability to process SSL (especially SSLv3) connections.In this example, I create two backend servers that accept the SSL certificate. If you have read the edition SSL certificates, you will see how to integrate them into Apache or Nginx to create a network server background to process SSL communication. You do not need to create or us

Haproxy achieves load balancing and dynamic/static Separation After haprxy Server Load balancer and dynamic/static separation, haproxy is more professional in these two aspects than nginx, including session persistence, cookie guidance, and url monitoring backend, mysql Server Load balancer is not available in nginx, b

Haproxy although with Ha, but it does is load balanced. Haproxy is working on the four floor, which means that it can represent a wider range of services than Nginx, with a higher performance than nginx. Compared to LVS, configurable and relatively good, the need for the machine is not more than LVS. So

Usage Requirements: load-balanced groups can be tocat+nginx with load Balancing clusters and LVS load balancing clusters. Compared to the three population sets, the LVS performance is the best, but the building complex, NINGX upstream module support cluster, but the cluster node fault check function is not many, performance is not comparable to haproxy. Relative to achieve what kind of effect: for the Enter

Overview:Haproxy is a cluster scheduling tool that provides high availability, load balancing, and proxy software based on TCP (layer fourth) and HTTP (layer seventh) applications, supporting virtual hosting, which is a free, fast, and reliable solution. Haproxy is especially useful for Web sites that are heavily loaded, and often require session-hold or seven-tier processing. Haproxy runs on today's hardwa

Recently, a company's business has been growing fast, resulting in heavy pressure on front-end servers. in order to solve this problem as soon as possible, I submitted a request for purchasing servers to the company. soon the company approved the request and the servers were in place. how can we reasonably utilize the resources of newly purchased servers (originally a front-end server)? First, we thought that using nginx for load was a recent rapid de
