elasticsearch 5 在windows7的安裝中Xmx的問題

@(elasticsearch 5)[windows|安裝]

elasticsearch2.4在windows7下沒問題。出現問題的是5版本

現象

cmd命令行，執行bin中的命令。報錯信息如下：Error: encountered environment variables that are no longer supported
Use jvm.options or ES_JAVA_OPTS to configure the JVM
ES_HEAP_SIZE=256m: set -Xms256m and -Xmx256m in jvm.options or add "-Xms256m -Xm
x256m" to ES_JAVA_OPTS

環境

我使用的是win7 64位系統16g內存，報錯，在公司的32位系統4g內存沒有這個系統。

先說做過沒有效果的方法

修改jvm.options文件的-Xms256m 和-Xmx256m，在32位系統有效果。在64位下，無論改為-Xms256m -Xms2g -Xms4g 報錯依舊。

注意：之前清理過系統，不確定是否有關系，但是在重裝java到1.8 到121版本，執行java -version 和 javac都沒問題。

解決-刪除或者注釋elasticsearch.bat中以下的檢測代碼
