Introduction

Redis is an in-memory data storage that is used by the CoreOne Suite. This how-to gives you a brief overview on how to install a redis cluster on Ubuntu.For supported versions see: Next-Gen Workflows - Redis

Step 1 - Check your prerequisits

  • Redis has to be installed on a Linux OS (Ubuntu, Redhat, Centos, etc.).

  • To install Redis, at least 3 instances are needed. The instances can be distributed across different servers, or concentrated on one (best practice will be shown in the examples below).

  • If the servers for Redis are in different network-zones, the servers must be able to communicate with eachother.

  • The following Firewall-Ports must be open:

    • 6379

    • 16384

    • 16379

    • 7001 (Cluster)

    • 7002 (Cluster)

    • 7003 (Cluster)

    • 7004 (Cluster)

    • 7006 (FClusterCluster)

Example

In our example we got 3 virtual Ubuntu-Servers.

Redis HA 1 (192.168.17.134)
Redis HA 2 (192.168.17.135)
Redis HA 3 (192.168.17.136)
