Introduction to Redis and installation of-centos

Redis is one of the most popular NoSQL systems today, and it is a key-value storage system. Similar to memcached, but largely compensates for the lack of memcached, which supports storing more value types, including string, list, set, Zset, and hash. These data types support Push/pop, Add/remove, and intersection sets and differences, and richer operations. Based on this, Redis supports sorting in a variety of different ways. Redis data is cached in the computer's memory and periodically writes the updated data to disk or writes the modification to the appended record file.
