To run ElasticSearch on as a non-root user (eg elasticsearch), you can follow the following steps.

First, make sure that you have the service wrapper installed (see Setting up ElasticSearch ).

We assume that $ES_HOME is set to the ElasticSearch install path, eg:

    export ES_HOME=/opt/elasticsearch

• Create the user:
  

      useradd -d $ES_HOME elasticsearch

• Open the service wrapper script in a text editor:
  

      vi $ES_HOME/bin/service/elasticsearch

  • uncomment the line starting RUN_AS_USER and change it to: RUN_AS_USER=elasticsearch
  • change the line starting LOCKDIR to: LOCKDIR=$ES_HOME/lock

• Create the lock dir:
  

      mkdir $ES_HOME/lock

• Change permissions on the ElasticSearch install dir: (Your gateway dir also needs to be writable by the elasticsearch user)
  

      chown -R elasticsearch $ES_HOME

• Edit /etc/security/limits.conf and add this line (this increases the number of files that the elasticsearch user can open, see Raising nofile limits if you have any problem here):
  

      elasticsearch     soft    nofile    32000

• Install the service wrapper to /etc/rc.d (or /etc/rc.d/init.d depending on your distribution):
  

     $ES_HOME/bin/service/elasticsearch -install

• ElasticSearch is now set up to run as a service on startup, running under the user elasticsearch. You can start and stop ElasticSearch using:
  • /etc/rc.d/elasticsearch start
  • /etc/rc.d/elasticsearch stop
