Haproxy is especially useful for Web sites that are heavily loaded, which typically require session maintenance or seven-tier processing. Haproxy is running on the current hardware and can support tens of thousands of concurrent connections altogether. and its operating mode makes it easy and secure to integrate into your current architecture while protecting your Web server from being exposed to the networ

For some time recently, I wanted to learn to transplant Ucgui. On the network to find a large number of transplant materials and learning tutorials, coupled with their continuous efforts, the successful completion of the transplant. Now will learn the problems encountered and has been recorded, the aspect of their own browsing, but also for beginners to provide a shortcut. Uc/gui Basic functions:

1, Haproxy introduction
The HAProxy is a high-performance tcp/http reverse proxy load Balancer server with the following features:
Complete HTTP request forwarding based on statically assigned cookies
Load balancing between multiple servers and session stickiness based on HTTP cookies
Primary and Standby server switchover
Accept access to specific ports for service monitoring
Enables smooth shutdown of a s
Shell practice: use shell to automatically receive and load the haproxy configuration file, so that the configuration takes effect. haproxy automatically receives the configuration and loads 002. Introduction to the background receiving configuration process: 0031. It is a while 1 background process 0042. Currently, it is a 30 s check. Is there any new configuration? If yes, continue. If not, rest for 30 s.
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 hardware to carry out, the common hardware has more expensive F5 and array and other commercial load balancer, its

Objective Software load Balancing is generally implemented in two ways: operating system-based soft load implementation and soft load balancing based on third-party applications. LVS is a kind of soft load based on Linux operating system, while Haproxy is a soft load based on third party application. Haproxy compared to the use of LVS is much simpler, but like LVs, hapr
Redis Redundancy Scheme (keepalived, HAProxy, Redis Sentinel)
If you're looking for a redis redundancy solution, I've found the following scenario, and I think I can try this out.

Initially, it was considered to be built using pacemaker, because the Redis author launched Sentinel's scenario, so this article uses the Sentinel scenario.
