準(zhǔn)備啟動(dòng)ES發(fā)現(xiàn)報(bào)錯(cuò)如下elasticsearch.keystore，一直沒(méi)弄清楚怎么回事，即便我按照keystore關(guān)鍵字搜索也沒(méi)有，后來(lái)我才意識(shí)到是權(quán)限的問(wèn)題啊兄弟們！你們看其他文件都是lin:lin，只有這個(gè)elasticsearch.keystore歸屬于root，因?yàn)樗窃谖覇?dòng)后才生成的，自然在我設(shè)置歸屬的時(shí)候沒(méi)有包含在內(nèi)，所以只要權(quán)限重新設(shè)置一下再啟動(dòng)就OK啦！

在正常啟動(dòng)之后，又會(huì)生成一個(gè)certs文件，在未設(shè)置的情況下，直接歸屬于lin:lin了。文章來(lái)源地址http://www.zghlxwxcb.cn/news/detail-528218.html
