Unable to start Elasticsearch

I've installed Elasticsearch on a clean, new, updated build of CentOS (7.7.1908). This installation is in support of a Wazuh installation using instructions found here:
When I get through the installation process and I'm on step 4. Enable and Start the Elasticsearch Service, the service errors out with very little additional information. Something like service exited with an error. The screenshot attached below;

Copy and paste the error stack.
Your screenshot is cut

Also any logs you can find from systemd or /var/log/elasticsearch, and ideally your /etc/elasticsearch.yml file, also, as problems usually are there. How much RAM and did you set JVM size?
