Elastic Search increase memory/heap

有时候ES会爆内存不够的Exception,这时候就需要增加系统分配给ES的内存。


增加的方法 1.设置系统环境变量

ES_HEAP_SIZE   3g
ES_MIN_MEM  3g
ES_MAX_MEM 3g


或者设置.elasticsearch.bat(用nodepad打开)  

找到

%elasticsearch_home%/bin/service.bat

foundJVM



if "%ES_MIN_MEM%" == "" set ES_MIN_MEM=3g
if "%ES_MAX_MEM%" == "" set ES_MAX_MEM=3g
