RedisIt is a memory-based high-performance Key-value database that stores data in the memory and regularly refreshes the data to the disk. This is a concern for high read/write efficiency. It supports various data structures, such as stirng, hashes, list, set, and sorted sets. 1. Download and install Wget http://download.redis.io/redis-stable.tar.gz Tar-zxvf redis-stable.tar.gz CD

The following is a description from the great God, the personal feel very clear, the collection.Why cluster?In general, in order to improve the responsiveness of the website, the hotspot data is always kept in memory instead of being read directly from the backend database. Redis is a good cache tool. Large web site applications, the amount of hot data is often huge, dozens of g hundreds of G is very normal, in this case, how to properly structure

I. Overview(can skip this paragraph directly) Redis has become more and more widely used as a NoSQL data service, and its greatest advantage over memcached is that it provides a richer data structure, so the application scenario is broader. The advent of Redis is a boon for the vast majority of web application developers, while a large number of open source personnel contribute client-side code, such as the
