将Elasticsearch升级到5.6.3

Question

我在最新版本的Elasticsearch 5.6.3中遇到同样的错误

Error: encountered environment variables that are no longer supported
Use jvm.options or ES_JAVA_OPTS to configure the JVM
ES_HEAP_SIZE=1024m: set -Xms1024m and -Xmx1024m in jvm.options or add "-
Xms1024m -Xmx1024m" to ES_JAVA_OPTS

我试图在bin / elasticsearch中添加ES_JAVA_OPTS =＆＃34; -Xms1024m -Xmx1024m，但我得到同样的东西。

Answer 1

您需要仔细阅读错误消息。

解决方案1：打开$ES_HOME/config/jvm.options并修改以-Xms和-Xmx

开头的行

-Xms1024m
-Xmx1024m

或解决方案2：在启动Elasticsearch之前使用环境变量

> export ES_JAVA_OPTS="-Xms1024m -Xmx1024m"
> bin/elasticsearch
