Question

我有一组通过SSH连接的Jenkins奴隶。几个月来他们一直都很好。今天早上，我发现所有奴隶都已断开连接，当我尝试启动代理时，所有奴隶都有同样的错误：

01/05/18 16:27:13] [SSH] Starting slave process: cd "/home/ubuntu/jenkins_slave" && java  -jar slave.jar
<===[JENKINS REMOTING CAPACITY]===>channel started

Slave JVM has not reported exit code. Is it still running?
[01/05/18 16:27:20] Launch failed - cleaning up connection

[01/05/18 16:27:20] [SSH] Connection closed.

我发现的一个常见问题是Jenkins和Java版本之间的不匹配，但我相信我的兼容（Jenkins服务器说2.46.3，奴隶都有Java 1.7）。

关于“它是否仍在运行？”，我没有看到Jenkins从属进程正在运行：

ps aux | grep java

什么都不返回。

我无法在奴隶端找到任何Jenkins日志。我在主方找到的所有日志只重复上面粘贴的错误。

Jenkins无法通过SSH启动奴隶代理 - 一夜之间断开连接
