Redis Cluster, a data sharding solution that automatically manages replication and failover.

With Redis version 3.0 and above, you can use That means that one of the slave nodes will be elected master and all other slave nodes will be configured to use the new master. Sentinel can be configured to monitor both master and slave instances, and will perform automatic failover if the master node is not working as expected. The master/slave setup described above can be made highly available with It will also allow distribution of reads among groups of slave copies as long as all write operations are handled by the master server. The simplest option, covered below, is master/slave replication, which creates copies of data. Redis provides several options for setting up distributed data stores. Redis documentation recommends the size of your swap disk match the amount of memory available to your system. Make sure that the following values are set for the appendonly and appendfsync settings in nf:Дepending upon your usage, you may find it necessary to add extra swap disk space. For the greatest level of data safety, consider running both persistence methods.Д«ecause the Point-in-time snapshot persistence is enabled by default, you only need to set up AOF persistence:

Append-only logs of all the write operations performed by the server (AOF).Д®ach option has its own pros and cons which are detailed in the Redis documentation.

Point-in-time snapshots of the dataset, made at specified intervals (RDB).

Redis provides two options for disk persistence: In this section, youвЂ™ll configure some basic persistence and tuning options for Redis. If Redis is running, it will return: PONG Verify that Redis is running with redis-cli: redis-cli ping Optional: To automatically start Redis on boot: sudo systemctl enable redis

This document provides both instructions for deploying the Redis server, and an overview of best practices for maintaining Redis instances on CentOS 7. Redis can be made highly available with Redis Sentinel and supports automatic partitioning with Redis Cluster. Redis features built-in transactions, replication, and support for a variety of data structures such as strings, hashes, lists, sets, and others. It can be used as a key-value database, or as a cache and message broker. Redis is an open-source, in-memory, data structure store with optional disk writes for persistence.
