I am trying to install ELK stack on RHEL linux using RPM packages downloaded.I could install only with root as it requires permissions for /etc directory. But after the installation it created users for logstash and elasticsearch. But when I am trying to run ES with root user its throwing error
org.elasticsearch.bootstrap.StartupException: java.lang.RuntimeException: can not run elasticsearch as root.
I want to use newly created users to run, How to enable those users to run ES, stash ?
