Jenkins SSH slave无法创建/ home / <user> / jenkins </user>

Question

在Jenkins上配置ssh slave时，在ec2实例上运行，当我点击＆＃34;启动Slave Agent＆＃34;时，我收到以下错误消息。

此节点的Jenkins配置如下：

请注意我已经设置了JavaPath属性，因为Jenkins＆＃34;无法找出java版本的Java＆＃34; （那是我收到的错误信息）

知道如何解决这个问题吗？感谢

Answer 1

我有同样的问题。阅读以下帖子talking about new version后，在我正在使用的SSH插件上发现了一些错误。

所以我访问了管理插件 - ＆gt;已安装 - ＆gt;搜索'SSH'（通过删除选择禁用SSH相关客户端）
基本上你需要：

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

解决了这个问题，我已经在第6步JENKINS-SETTING UP MASTER SLAVE ENVIRONMENT的本文档中显示的其他设置之后成功连接了。 （slave.jar -jnlpUrl ....）
希望这将有助于将来的某些人。

您需要在用户有权访问的ec2实例上提供有效路径。
