虚拟机中的ES不能访问问题解决

我是靠谱客的博主大气眼神，这篇文章主要介绍虚拟机中的ES不能访问问题解决，现在分享给大家，希望可以做个参考。

今天遇到一个问题即在linux虚拟机中的elasticsearch不能在宿主机上访问？

系统版本：CentOS 7

elasticsearch版本：最新版的7.5.2

JDK版本：JDK13

说明：好像7.5.2最低使用环境是JDK11

第一个反应：难道不能ping通？

之后我试了试两边都能ping通。嗯，不是这个问题...

第二个想法是9200没开？

确实没开，但是开了之后还是不行，网上有说开80端口。试了之后还是虚拟机我行我素....B了狗了，最后我把防火墙关了....重启es还是不行

最后在网上找到一个说是在es的配置文件中地址设置有三种：

1、network.host 这个是内网地址，你可以设成127.0.0.1(这个好像是默认的)

2、network.publish 这个是发布地址，这个是唯一用在集群通信上的

3、重点来了，network.bind_host 这个就是我们要改的，设置这个可以让es绑定多个ip，因此我们可以把外网和内网ip都配上，相同云平台用内网ip访问，不同云平台用外网ip访问；

嗯，最后我这个设置成network.bind_host: 0.0.0.0

这个详细的看这里：https://blog.csdn.net/totally123/article/details/79569537

友情提示：yml格式在冒号后面有空格哦；

哦，还有一点就是设置了这个之后好像会报

ERROR: [1] bootstrap checks failed
[1]: the default discovery settings are unsuitable for production use; at least one of [discovery.seed_hosts, discovery.seed_providers, cluster.initial_master_nodes] must be configured

嗯.....这段话的意思大概是：

错误：[1]引导检查失败

[1] ：默认发现设置不适合生产使用；必须至少配置[discovery.seed_hosts，discovery.seed_providers，cluster.initial_master_nodes]之一

那么把yml配置文件中的cluster.initial_master_nodes属性改成当前节点名称就好了...

到此这个es就可以在宿主机上访问es了。

我想了想，还是把我的配置文件内容加上。网上的大佬，如果有不对的地方多指教！！！
