Dear @stephenb ,
I don't ask about magento, but ES, I heard a lot about and really would use in my projects, I want run ES properly on my laptop
ok, I found a link where someone talked about increasing memory in jvn.options (xms & xmx 1g) and ES starts finally
systemctl status elasticsearch.service

Why isn't this mentioned in the official install documentation ? 
Now I finally create the token 
sudo /usr/share/elasticsearch/bin/elasticsearch-create-enrollment-token -s node
eyJ2ZXIiOiI4LjExLjMiLCJhZHIiOlsiMTkyLjE2OC44LjEwMDo5MjAwIl0sImZnciI6IjZjYmU5MmNiNDgxZjU2NWNmNzY0NmUzODUxNDRlNGIwYzMwZTc3ZjBiY2YxYWQ1ZjVlNTUwOGNiZWUxNzMxMTEiLCJrZXkiOiJ2M1BIeTR3QmxNLUNEZzNuSDlDRDpyTFRWNHNZb1FPMkt4RHk4SkhpdERRIn0=
But 
:
sudo /usr/share/elasticsearch/bin/elasticsearch-reconfigure-node --enrollment-token
eyJ2ZXIiOiI4LjExLjMiLCJhZHIiOlsiMTkyLjE2OC44LjEwMDo5MjAwIl0sImZnciI6IjZjYmU5MmNiNDgxZjU2NWNmNzY0NmUzODUxNDRlNGIwYzMwZTc3ZjBiY2YxYWQ1ZjVlNTUwOGNiZWUxNzMxMTEiLCJrZXkiOiJ2M1BIeTR3QmxNLUNEZzNuSDlDRDpyTFRWNHNZb1FPMkt4RHk4SkhpdERRIn0=
ERROR: Skipping security auto configuration because it appears that the node is not starting

Any idea please ?
