Few questions around ELK Stack

Elastic Stack Elasticsearch
1

Hi Team,

Can you please help me answer below questions -

  1. what is the use of elastic.co key (rpm --import https://artifacts.elastic.co/GPG-KEY-elasticsearch)

  2. what does bootstrap.memory_lock: true (elasticsearch.yml) , LimitMEMLOCK=infinity (elasticsearch.service) and MAX_LOCKED_MEMORY=unlimited (vim /etc/sysconfig/elasticsearch) signify.

  3. Use of Nginx and httpd-tools package (yum -y install nginx httpd-tools).

Kind Regards,
Asif Bhat

  1. For installing DEB/RPM packages and knowing they are the offical ones.
  2. Take a look at https://www.elastic.co/guide/en/elasticsearch/reference/current/system-config.html
  3. That's not a question :wink:
