If you need to setup SSL with a WordPress multisite package, managed by bitnami, you are really in luck! They have packaged a really great tool to help you install SSL certificates on the site. Not only is it simple, but it uses Let’s Encrypt and provides a free cert!

Special thanks to AWS Lightsail for the documentation and bitnami for managing the tool.


Bitnami provides their own HTTPS configuration tool, bncert-tool, for installing standard Let’s Encrypt certificates. Bitnami stacks released after May 10, 2019 include bncert-tool by default.

The bncert-tool tool automatically performs the following procedures:

  • Configures HTTPS certificates on Bitnami stacks.
  • Creates automatic certificate renewals.
  • Sets up HTTP to HTTPS redirections.

Prerequisites and limitations

  • Make sure that the domain in the DNS records points to the IP address of your Lightsail instance.
  • Certificate creation for wildcard domains isn’t possible using the bncert-tool.

Run the following command to launch the Bitnami HTTPS configuration tool:

sudo /opt/bitnami/bncert-tool
