Warning: You need to recreate your cluster if you’re already running and want to change to SSL.

  • Create certificates
openssl req -new -x509 -days 3650 -nodes -keyout galera.key -out galera.crt
  • Copy them over and configure into use
# grep wsrep_provider_options /etc/mysql/conf.d/galera.cnf
  • Shut down the cluster and bootstrap it
