Out of whatever reason you seem to have a /etc/elasticsearch/tempelasticsearch directory/link/file - you shold not have any additional files in there, except what is needed by ES. Try deleting that entity and see if that works.

Timshs · August 3, 2018, 9:54am

Still same error.

Running on 17.10 with ES 5.6.5

If you tell me exactly which logs you need to see I will find them.

spinscale · August 3, 2018, 11:18am

the systemd start up logs from the most recent try to start

this is the culprit

You configured memory locking, but Elasticsearch is not allowed to do this, because the operating system is not configured properly.

The last link shows what to check for.

Thank you so much for info. I got it up and running after taking the node out of the cluster I tried to setup
