Create a highly available Redis cluster using Redis Sentinel through the Linode Ansible Collection through the Linode Marketplace. Redis is an open-source, in-memory, data-structure store, with the optional ability to write and persist data to a disk, which can be used as a key-value database, cache, and message broker. Redis features built-in transactions, replication, and support for a variety of data structures such as strings, hashes, lists, sets, and others.
| Software | Version | Description |
|---|---|---|
| Redis | 7.07 | In-memory key value store |
| Redis Sentinel | 7.0.7 | Redis process that provides high availability to the Redis cluster. It performs automatic primary promotion within the cluster |
| Firewalld | 0.9.3-2 | Firewall utility to enforce exclusive network communication within the cluster |
Supported Distributions:
- Ubuntu 22.04 LTS
Deployment guide:
Additonal resources:
Once the provisioning of the cluster is complete, you can find the credentials to access cluster on the first Redis node. The file will be in the home directory of the sudo user that was created:
/home/admin/.deployment-secrets.txt:
# system user
user: admin
password: eX4_&mpl3Ep_Pa55worD!!
# redis password
redis-cli --askpass:
eX4_&mpl3Ep_Pa55worD!!
