SchemeIn the previous article, we discussed the theoretical knowledge of load balancing, and this article I intend to talk about practical methods and problems encountered in practice Scenario: Haproxy HTTP Layer Load Balancing Install a Haproxy service, two Web services Haproxy:192.168.1.227:80 Web1 Http://192.168.1.226:8081/loginWEB2 Http://192.168.1.246:8888/l

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

Install Nginx (as HTTP server) and Haproxy (reverse proxy) in the test environment, and configure Haproxy log output to/var/log/haproxy.log, take note.It should be explained that this is only a basic installation, configuration method, and does not involve specific usage in a production environment.First, install Nginx1.

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

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

Haproxy 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. The haproxy runs on the current hardware and can support tens of t

These days I compare nginx and Haproxy, and come to a surprising result.First, some background information is presented. For a long time, we bengler the Nginx as the main Web server for our project, just as we did under mongrel as a proxy for rails. Nginx is a very good small open source software, it occupies a small space, a reasonable configuration language, advanced features and fast. However, we quickly discovered that the load balancing feature o

This section describes the knowledge of haproxy. 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.

Previously, we made a service that implements the LDAP query proxy through Haproxy + Keealived. I felt pretty good and decided to use it to proxy public Exchange requests. TMG is not updated, and the configuration is a little complicated, and the service will die if it does not move. If you cannot understand the following information, go to my previous article Haproxy + keepalived to configure LDAP proxy.

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 PV less than 10 million, with Nginx can be completely; if there are many machines, you can use DNS polling, LVS consumes more machines or more, large web sites or important services, and the server is relatively long, You can consider using LVS. One is through the ha
