elasticsearch无法安装head插件

Question

我打算为elasticsearch安装头插件。

在这两个官方文档中，http://mobz.github.io/elasticsearch-head/ 和 http://docs.couchbase.com/admin/elastic/install-plugin.html 他们都说要使用这个：

bin/plugin -install mobz/elasticsearch-head 

我做了，但我收到以下错误：

当我试图诊断错误时，我发现 elasticsearch.yml 文件中可能有问题。我去了那个文件，用notpadd++打开它，除了最后三四行外，所有的都被注释了，它们是无法理解的字母。这是他们的打印屏幕：

你能帮忙吗

在那个文件中你不应该有那些字符。删除它们并重新开始。或者获取一个干净的 ES 实例，从中获取配置文件并使用它。
