linux - Jenkins SSH slave 无法创建/home//jenkins

Question

在运行在 ec2 实例上的 Jenkins 上配置 ssh 从站时，单击“启动从站代理”时收到以下错误消息。

此节点的 Jenkins 配置如下:

请注意，我已经设置了 JavaPath 属性，因为 Jenkins“无法确定 java 的 Java 版本”(这是我收到的错误消息)

知道如何解决这个问题吗？谢谢

Answer 1

我遇到了同样的问题。看完下面的帖子talking about new version ，意识到我正在使用的 SSH 插件出了问题。

所以我访问了管理插件 --> 已安装 --> 搜索“SSH”(通过删除选择禁用与 SSH 相关的客户端)
基本上你需要:

• 已禁用 - SSH Slaves 插件(可能与 Jenkins 一起提供)
  
• 添加了 SSH 插件(2.4 版)。

这解决了这个问题，在本文档第 6 步中显示的其他设置之后我已经成功连接，JENKINS-SETTING UP MASTER SLAVE ENVIRONMENT . ( slave.jar -jnlpUrl ....)
希望这会在将来帮助某人。
