最近在部署elasticsearch-7.3.1时遇到如下问题
org.elasticsearch.bootstrap.StartupException: ElasticsearchException[Failure running machine learning native code. This could be due to running on an unsupported OS or distribution, missing OS libraries, or a problem with the temp directory. To bypass this problem by running Elasticsearch without machine learning functionality set [xpack.ml.enabled: false].]

关键词：xpack.ml.enabled: false
进入config目录下在elasticsearch.yml添加一条配置：
xpack.ml.enabled: false

问题解决，正常访问。这个错误是因为在Centos中运行了Macos下的es安装包，换成linux的包，正常启动。
