未能启动詹金斯奴隶

Question

我正在尝试在我们的服务器上设置jenkins群集。配置从属节点后，尝试从主节点启动该从属节点后，无法启动。

错误日志

我注意到的一件事是它似乎存在java版本不匹配的问题。

似乎返回java版本1.5。但我检查了奴隶和主服务器。它目前安装了Java 1.8。

ldndsr000004921$ java -version
java version "1.8.0_66"
Java(TM) SE Runtime Environment (build 1.8.0_66-b17)
Java HotSpot(TM) 64-Bit Server VM (build 25.66-b17, mixed mode)

jenkins系统环境如下：

请指教？

这是由于javPath设置不正确。我能够通过指定javaPath来修正它来修正它。

设置完成后，jenkins代理能够成功启动，如下所示
