如何在ElasticSearch上使用最大4GB的内存？

Question

I am trying to optimize the use of memory in Elastic Search to use max 4GB on a macOS. I know the following code works on Windows, but when I run it on Mac it doesn't work:

./elasticsearch -Xmx4g -Xms4g

When running it on Mac it says the following message:

ERROR: Parameter [-Xmx4g]does not start with --

I have tried to run it without "-" and still does not work.

Any ideas on how to run it on Mac?

Answer 1

Try using this command instead

ES_JAVA_OPTS="-Xms4g -Xmx4g" ./bin/elasticsearch

or use the jvm.options file mentioned here
