当出现 illegal_argument_exception 时候 意思是非法参数异常。也就是URI 缺少参数。在创建Elasticsearch的index 有一个 type （也就是Mysql数据中的表名）， 在curl的时候没有输入这个type的话

unknown setting [index.status] please check that any required plugins are installed, or check the breaking changes documentation for removed settings 出现这个错误，这个错误就说明 你在插入数据的时候 不知道你要把你的这条数据插入到哪个表里面去，所以就报错了。类似于Mysql 因为要指定一张表的插入，不能随便插入不是。。。。

所以 正确的方法 URL 是

curl -H "Content-Type: application/json" -X PUT 'http://localhost:9200/index/type' -d
