The replication process cannot communicate with each other. The problem is solved by changing to the TCP mo

Build highly available reverse proxies with Haproxy and keepalivedBuilding high-availability reverse proxies with haproxy and keepalived in the case of a site with a large number of accesses, as the traffic increases, a single server is unable to process all the requests, which requires multiple servers to divert a large amount of requests, that is, load balancing. In the case of load balancing, these reque

Compared with other Server Load balancer systems, the configuration and use of haproxy is relatively simple.The following is a self-installed and

multi-network segment);2, can add some of the shortcomings of Nginx such as the session of the maintenance, cookie guidance and other work;3, support the URL detection backend server;4, it is just like the LVS, itself is only a load balancer software, simply from the efficiency of the haproxy more than Nginx has a better load balancing speed, in concurrent processing is better than nginx;5, Haproxy can loa

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.

Conclusion: through the two examples above, we have learned about the power of haproxy in load balancing, and of course we can also achieve mysql read load balancing, for more advanced features, let's get to know it.

What is Haproxy?Haproxy is a free and open source software written in C that provides high availability, load balancing, and TCP and HTTP-based application proxies that can run on most major Linux operating systems.This experiment uses three servers to build a Web cluster, haproxy as a dispatch server, two Nginx server

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
