无法在詹金斯启动新的奴隶

Question

我正在尝试为我的 jenkins master 启动一个新的从站，但我收到以下错误：

我认为主要问题是这条线：原因：java.io.IOException：无法找到登录表单。但是我似乎无法在网上找到有关此问题的任何信息.. 我在从服务器上同时安装了 JDK 和 JRE，但是当我启动从服务器时它仍然在尝试下载 JDK，我不知道为什么..

Answer 1

这与 New Oracle website prevents the JDKInstaller to download binaries from archives。甲骨文不久前更改了他们的网站。

您必须下载 Java 并将其单独安装在您的从站上。（例如：sudo apt-get install default-jre）

这样就可以了:-D。
