Background introduction:Currently, Redis does not have an official HA scenario similar to MySQL proxy or Oracle RAC.The master-slave switching scheme named Sentinel has been formally provided #Redis version 2.8 (attached, not tested)Therefore, how to automatically transfer in the event of a failure is a problem that needs to be solved.Through the search for some information on the Internet, it is recommende

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.

In the MySQL world, Haproxy is often used as a software load balancer. Peter Boros explains how to use the Percona xtradb cluster (PXC) to set it up in a previous message. So it only sends the query to the applicable node. The same method can be used for general master-slave settings to read the load and spread across multiple nodes. However, with MySQL replication, another factor starts to work: replication latency. In this case, the mentioned Percon
