安装x-pack java.net.UnknownHostException:artifacts.elastic.co

环境：

• 世纪7
• 弹性搜索：5.2.2
• 基巴纳5.2.2

在elasticsearch中，当我安装x-pack时，出现以下错误：

我补充说

127.0.0.1 localhost

我被困在这一点上。如何解决此问题？

此时因为我的虚拟机无法连接到外部网络而导致(这时因为我的虚拟机不能连接外网造成的）

---

在windows网络连接-本地连接-共享-整数连接共享检查中删除(在窗户中网络连接 -- 本地连接 -- 共享 --- 整数连接共享 勾选去掉）

尝试使用http和https设置导出系统变量

ES\u JAVA\u OPTS

。在ubuntu中，您可以执行以下操作：

export ES_JAVA_OPTS=“$ES_JAVA_OPTS-Dhttp.proxyHost=host-Dhttp.proxyPort=port-Dhttps.proxyHost=host-Dhttps.proxyPort=post”

希望它能有所帮助，因为它解决了6.0.0版elasticsearch的相同问题

127.0.0.1 localhost
