Ansible-role to install Redis5 Sentinel on Centos/RHEL 7 (using Satellite). This role has been developed to cater analytics of a high-volume website with Matomo. We use Redis hosts with 64Gb to cache the event queues before processing into MariaDB.
Yum with Software Collections, this role has been developed for on-prem use.
