Compared with other Server Load balancer systems, the configuration and use of haproxy is relatively simple.The following is a self-installed and
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 haproxy is good to use under certain demand. For example, us

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. H

Keepalived is mainly used to implement fault isolation of real machines and failover between load balancers. It can be switched at Layer 3, 4,
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 development of a company's business, the pressu
1. Preface The previous section implemented a technical solution based on LVS (DR) + keepalived cluster. However, in terms of usage and maintenance, it was found that it is more difficult to maintain and implement than the haproxy + keepalived technical solution, the haproxy + keepalived cluster for Web applications is sufficient. Therefore, we recommend the haproxy

Software load balancing is generally implemented in two ways: Software load implementation based on the operating system and software load implementation based on third-party applications. LVS is a kind of soft load based on the Linux operating system. haproxy is an open-source software load based on the third application.

The HAProxy reverse proxy server supports dual-host hot standby and supports virtual hosts. the configuration is simple and has a very good server health check function. When the back-end server of the proxy fails, HAProxy will automatically remove the server, and then automatically add the server after the fault is restored. Mysql Cluster Proxy The HAProxy rever
