踩坑：

当我们访问ip+9200 验证是否启动成功时报错

received plaintext http traffic on an https channel, closing connection Netty4HttpChannel{localAddress=/172.16.5.10:9200,
remoteAddress=/172.16.11.68:11111}

如图：
在这里插入图片描述
原因：Elasticsearch开启了安全认证
解决：在config/目录下面的elasticsearch.yml配置文件，把安全认证开关从原先的true改成false，实现免密登录访问即可，修改如图：

笔者使用的是Windows版elasticsearch，但笔者觉得linux上的解决方法也是相通的，相信聪明的读者很快就能找到解决的办法（看好你哟，加油！Fight）。1.问题："Win+R"，然后键入"cmd"打开命令窗口，进入elasticsearch安装目录，进入bin目录，使用"elasticsearch.bat"命令启动elasticsearch，然后输入网址：http://localhost:9200，网页却显示：“当前无法使用此页面”，网页显示如图1所示：图1 网页显示。

原因: ES8默认开启了ssl认证，导致无法访问9200端口 修改 elasticsearch.yml配置:xpack.security.enabled:把true改成false

ElasticSearch默认开启了安全认证，需要将安全认证关掉。ElasticSearch服务正常启动，但是在浏览器上无法访问。

Elasticsearch服务器收到了明文的HTTP流量，但该通道应该是用于HTTPS的。因此，服务器关闭了这个连接。找到里面的 xpack.security.enabled 这个是控制是否开启https格式的配置项。然后 找到 elasticsearch.yml 打开它进行编辑。我们可以打开ES目录下的 config 配置文件存储目录。今天第一次装ES 出师不利 直接先来了一个警告。如果是true 那确实会有这个问题。然后 再次运行服务 它就起来啦。我们改成 false。
启动ElasticSecrch无法访问问题： received plaintext http traffic on an https channel, closing connection Netty
世上哪有什么岁月静好,不过是有人替你负重前行

原因是Elasticsearch在Windows下开启了安全认证，虽然started成功，但访问http://localhost:9200/解决方法就是修改ElasticSecrch.yml的配置文件，位置在哪就不用多说了叭，修改安全认证的地方。当启动Elasticsearch后，在浏览器输入地址 http://localhost:9200/标红框框的地方true改为false就好了，再去访问浏览器：9200。

一劳永逸的解决办法是关闭安全认证，在config/elasticsearch.yml里。从es8.0开始，开启了安全机制，我们要访问https://ip+port才能访问到。，因为kibana默认是通过https连接的。如果用http访问，会出现以下错误。所以还需要修改kibana的配置。内容在配置文件的最底下。

原因是Elasticsearch在Windows操作系统下开启了ssl认证认证，虽然启动成功,但访问http://localhost:9300失败。这里启动elasticsearch.bat的时候系统分配的端口是9300,但是无论如何都打不开,尝试了使用9200就打开页面了,有大佬知道为什么吗。当启动Elasticsearch后，在浏览器输入地址 http://localhost:9300。在点击http://localhost:9200重新访问,页面就出来了。
