So then we started using haproxy to build the cluster. One, top

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

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.

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. "highly Available Redis Cluster | Simplicity is the keynote of all true elegance" Initially, it was considered to be built using pacemaker, because the Redis author launched Sentinel's scenario, so this article uses the Sentinel scenario.
