The method of installing Redis with Yum is detailed _redis

Introduced

Redis is a key-value storage system. Like memcached, it supports a relatively larger number of stored value types, including string (string), list (linked list), set (set), Zset (sorted set– ordered set), and hash (hash type). These data types support Push/pop, Add/remove and intersection-set and differential sets and richer operations, and these operations are atomic. On this basis, Redis supports a variety of different ways of ordering. As with memcached, data is cached in memory to ensure efficiency. The difference is that Redis periodically writes the updated data to the disk or writes the modification operation to the appended record file, and on this basis, it realizes the Master-slave (master-slave) synchronization.

V. Test usage commands
