It's important for modern applications to secure data transmission, and this includes databases like Redis. With Redis, it's possible to use Transport Layer Security (TLS) for encrypted connections, including in a replication setup where data is copied from a master server to one or more replicas.
Setting up a Redis master-replica configuration with TLS involves a few steps:
redis.conf) on the master server to enable TLS and specify your certificates and private key. You'll also need to set an encrypted port for clients to connect to.
tls-auth-clients directive is set to
no to specify that client authentication is not required.
redis.conf file to enable TLS and provide the certificate files as above, but also add a
replicaof directive pointing to the master server.
Remember to replace 'localhost' with the real address of your Redis servers in production setup.
Please refer to Redis's official documentation for most up-to-date and detailed instructions.
