java.lang.UnsatisfiedLinkError: Native library (com/sun/jna/linux-x86/libjnidispatch.so) not found in resource path解决方法是，从下面的地址下载最新的JNA-4.4.0.jar替换elasticsearch/lib/jna-4.4.0.jar

ElasticsearchException[X-Pack is not supported and Machine Learning is not available for [linux-x86]; you can use the other X-Pack features (unsupported) by setting xpack.ml.enabled: false in elasticsearch.yml]解决方法是： 在config/elasticsearch.yml添加一条配置：
xpack.ml.enabled: false如果成功的启动后，我们可以新开一个终端，使用curl来发送一次请求
