Elasticsearch unable to start with basic network settings 5.2.1

I have installed Elasticsearch 5.2.1 RPM manually. I have configured the basic network setting which I have utilized in my previous version. When I try to start the Elasticsearch it throwing me some error. The same setting was running in my older version 2.3.1 without any issues. I am not sure whether I need to add any additional setting for this.

My Configuration

cluster.name: ddlm.cluster

node.name: dd.sys.node-1

path.data: /ddlm/es/data/

path.logs: /ddlm/logs/elasticsearch_logs

bootstrap.memory_lock: true

My issue got resolved when I changed the setting in this file /etc/security/limits.conf. We need to add this two line in that file

<<username>> soft memlock unlimited
<<username>> hard memlock unlimited

After adding this line you can enable bootstrap.memory_lock: true

I have this issue too,I use tmux , sometimes in tmux your config not perform right,so you should restart your computer or run elasticsearch out of tmux .
