ES（elasticsearch）报错elasticsearch.keystore

ES（elasticsearch）报错elasticsearch.keystore

准备启动ES发现报错如下elasticsearch.keystore，一直没弄清楚怎么回事，即便我按照keystore关键字搜索也没有，后来我才意识到是权限的问题啊兄弟们！你们看其他文件都是lin:lin，只有这个elasticsearch.keystore归属于root，因为它是在我启动后才生成的，自然在我设置归属的时候没有包含在内，所以只要权限重新设置一下再启动就OK啦！

在正常启动之后，又会生成一个certs文件，在未设置的情况下，直接归属于lin:lin了。
