#!/bin/sh # CONTROLLING STARTUP: # # This script relies on few environment variables to determine startup # behavior, those variables are: # # ES_CLASSPATH -- A Java classpath containing everything necessary to run. # JAVA_OPTS -- Additional arguments to the JVM for heap size, etc # ES_JAVA_OPTS -- External Java Opts on top of the defaults set # # # Optionally, exact memory values can be set using the following values, note, # they can still be set using the `ES_JAVA_OPTS`. Sample format include "512m", and "10g". # # ES_HEAP_SIZE -- Sets both the minimum and maximum memory to allocate (recommended) # # As a convenience, a fragment of shell is sourced in order to set one or # more of these variables. This so-called `include' can be placed in a # number of locations and will be searched for in order. The lowest # priority search path is the same directory as the startup script, and # since this is the location of the sample in the project tree, it should # almost work Out Of The Box. # # Any serious use-case though will likely require customization of the # include. For production installations, it is recommended that you copy # the sample to one of /usr/share/elasticsearch/elasticsearch.in.sh, # /usr/local/share/elasticsearch/elasticsearch.in.sh, or # /opt/elasticsearch/elasticsearch.in.sh and make your modifications there. # # Another option is to specify the full path to the include file in the # environment. For example: # # $ ES_INCLUDE=/path/to/in.sh elasticsearch -p /var/run/es.pid # # Note: This is particularly handy for running multiple instances on a # single installation, or for quick tests. # # If you would rather configure startup entirely from the environment, you # can disable the include by exporting an empty ES_INCLUDE, or by # ensuring that no include files exist in the aforementioned search list. # Be aware that you will be entirely responsible for populating the needed # environment variables. # Maven will replace the project.name with elasticsearch below. If that # hasn't been done, we assume that this is not a packaged version and the # user has forgotten to run Maven to create a package.
