High-availability cluster for HAproxy Based on Keepalived 1. Introduction to Keepalived Keepalived is used to detect the status of a web server. If a web server crashes or fails to work, Keepalived will detect it and remove the faulty web server from the system, when the web server is working normally, Keepalived automatically adds the web server to the server group. All these tasks are completed automatically without manual interference. All you need

A brief introduction to the principle1.HAProxyHaproxy provides high availability, load balancing, and proxies based on TCP and HTTP 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 hardware and can support tens of thousand

Software load Balancing is generally implemented in two ways: the implementation of soft load based on operating system and the implementation of soft load based on third party application. LVS is a kind of soft load based on Linux operating system, Haproxy is an open source and soft load based on the third application implementation.Haproxy compared to the use of LVS is much simpler, the function is also very rich. Currently,

Next I will describe in detail the integration of Haproxy and Nginx directory browsing, and integration with Zabbix I will post the

Haproxy works in the user space (Layer 7) and can identify data at the application layer (HTTP packets. Therefore, you can schedule requests to different service groups based on different request types. That is, haproxy can identify the request information of HTTP packets for access control; For example: A group of servers Process Dynamic Resources: JSP and PHP A group of servers process static resources, s

I. background The company recently used the exchange mail system to build a highly available mail system architecture. Front-End Server Load balancer uses Microsoft's NLB to achieve CAS load balancing. However, some problems have also been found in the solution implementation project. using NLB to generate a large number of broadcast reports in the network causes serious packet loss problems. Then we use haproxy to replace NLB to achieve CAS load ba

HAProxy: Implements an event-driven, single-process model that supports tens of thousands of of concurrent connections to provide highly available, load-balanced, and proxy service solutions for TCP and HTTP applications, especially for high-load Web sites that require a durable connection or a 7-tier processing mechanismProxy (HTTP):Forward Proxy:Reverse proxy:Agent role: Web caching (acceleration), reverse proxy, content routing (forwarding requests

Ps:nginx/lvs/haproxy is currently the most widely used three load balancing software, I have been implemented in a number of projects, reference to some information, combined with some of their own experience, summed up. The general use of load balancing is to use different technologies depending on the stage of the site's ascent. Specific application needs to be specific analysis, if it is small and medium-sized Web applications, such as the daily P

Working with scenes Using Haproxy to carry out load balancing, for data transmission under socket, non-HTTP access load balancing.Assuming that the scenario is as follows, Terminal 1 and Terminal 2 are responsible for collecting data and then want to forward the data to the server for analysis through the load balancer.Hope:1, when two terminals are working properly, but only one server (server 1), will send all the data to this server.2, when two te
