A Summary of the Redis Installation and Configuration ProcessĪ complete Redis installation, including basic configuration tasks, consists of the high-level steps outlined below. To store large amounts of data, we recommend hosting Redis on a High Memory Linode. Redis requires a robust, stable hosting environment to function properly. Redis provides persistence methods to either write the current database state to disk or record all transactions in a log. However, you can only store as much data as memory allows. Since Redis is an in-memory database, it runs quickly with low latency. Redis contains a large library of commands, but it does not have a query language or relational capabilities. Redis supports concurrency since all single-command operations in Redis are atomic. If you’re not familiar with the sudo command, see the Linux Users and Groups guide. Commands that require elevated privileges are prefixed with sudo. This guide is written for non-root users.
