一、确认问题

elasticsearch节点启动失败

elasticsearch节点集群日志中有类似如下报错

bash 复制代码

Unrecognized VM option 'UseAVX=2'
Error: Could not create the Java Virtual Machine.
Error: A fatal exception has occurred. Program will exit.
    at org.elasticsearch.tools.launchers.JvmErgonomics.flagsFinal(JvmErgonomics.java:126)
    at org.elasticsearch.tools.launchers.JvmErgonomics.finalJvmOptions(JvmErgonomics.java:88)
    at org.elasticsearch.tools.launchers.JvmErgonomics.choose(JvmErgonomics.java:59)
    at org.elasticsearch.tools.launchers.JvmOptionsParser.jvmOptions(JvmOptionsParser.java:137)
    at org.elasticsearch.tools.launchers.JvmOptionsParser.main(JvmOptionsParser.java:95)

二、处理办法

问题原因

该错误只会在arm环境下产生。
UseAVX=2该选项是为x86架构的处理器优化的，而ARM处理器不支持该选项

处理办法

注释或删除掉elasticsearch服务的jvm.options文件中的10-:-XX:UseAVX=2 配置，并重启es服务

bash 复制代码

# 10-:-XX:UseAVX=2
