早上在服務器上安裝elasticsearch集羣，在其中的一臺上面安裝好elasticsearch以後安裝了一些插件，其中一個插件是marvel，結果多是新版本不支持這個插件，就沒有安裝成功，也就索性沒管，安裝了head和kopf插件，安裝完以後改了一下配置文件css

systemctl restart elasticssearch重啓，結果卻報錯了，報錯以下：java

發現下面爆了個licence錯誤，說 marvel plugin requires the license plugin to be installed，因而想到那個插件沒有安裝成功，去plugin目錄下面把marvel-agent目錄移除了，重啓就正常了node
