Updating SSL/TLS certificates for Previous Releases

For version 5.0.2

Warning -
If the SSL/TLS certificate/s were configured in RS 5.0.2 without using the REST API, but by updating the certificate/s on the disk, contact Redis Labs support before you upgrade the cluster to a later version as certificates are overwritten during upgrade.

To update a certificate in the cluster, upgrade the cluster to RS 5.2.0 or above and then update the certificates with the REST API.

For versions below 5.0.2

Note: If you choose to update the certificates you must follow these steps on all machines that are part of the cluster, and on all machines that you add to the cluster in the future.

To update a certificate in the cluster, on each cluster node:

  1. On the cluster machine, after RS has been installed, navigate to the /etc/opt/redislabs folder.
  2. Replace the following certificate files with your own files and rename them to the same exact names as the original files:

    • For the management UI certificate and private key:
      • cm_cert.pem
      • cm_key.pem
    • For the REST API certificate and private key:
      • api_cert.pem
      • api_key.pem
    • For the database endpoint encryption certificate and private key:
      • proxy_cert.pem
      • proxy_key.pem

    Note: A certificate for the databases' endpoint should be assigned for the same domain as the cluster name. For example, for a cluster with the name "" the certificate should be for "redis-*"

  3. If you are using a certificate issued by an intermediate certificate authority (CA), you should also add the chain file named chain_certs.pem to the same folder.

  4. After replacing the files, restart the relevant service by running the following command from the operating system command-line interface (CLI):

    • For the management UI: supervisorctl restart nginx
    • For the REST API: supervisorctl restart nginx
    • For the database endpoint encryption: supervisorctl restart dmcproxy

    Note: Restarting the dmcproxy service will disconnect any existing clients connected to any of the databases.

  5. Repeat these steps on all other machines in the cluster.
