Redis Tutorials

This guide outlines how to install client programs for a variety of database management systems (DBMSs) — including PostgreSQL, MySQL, Redis, and MongoDB — on an Ubuntu 18.04 server. It will also explain how to use these programs to connect to a managed database instance.

This tutorial outlines one method you can use to migrate data to a Redis instance managed by DigitalOcean. The method involves creating a Bash script that uses Redis’s internal migrate command to securely pass data through a TLS tunnel configured with stunnel. This guide will also go over a few other commonly-used migration strategies and why they’re problematic when migrating to a DigitalOcean Managed Database.

In this tutorial, you’ll import database metrics, generated by the Redis INFO command, into Elasticsearch via Logstash. This entails configuring Logstash to periodically run the command, parse its output, and send it to Elasticsearch for indexing immediately afterward. The imported data can later be analyzed and visualized in Kibana. By the end of the tutorial, you’ll have an automated system pulling in Redis statistics for later analysis.

Stunnel is an open-source proxy used to create secure tunnels, allowing you to communicate with other machines over TLS. In this guide, we will walk through installing and configuring stunnel so you can connect to a managed Redis instance over TLS with redis-cli.
