linux – Jenkins Slave Issue – 无效的流标题：099EACED

Jenkins 2.7.4安装在RedHat服务器中,Linux Slaves通过选择“通过执行命令在主服务器上启动代理”选项进行配置.我们创建了一个Shell脚本,它在Jenkins版本2.7.4中运行良好.

现在我们将Jenkins升级到2.121.1.现在,同一个脚本会抛出错误

如果我在Manage Jenkins中禁用SSHD端口 – >配置安全性,然后我就可以启动我的奴隶了.但是在我的脚本中,我将使用Jenkins-cli.jar触发一个作业,将二进制文件从master复制到slave.
java -jar jenkins-cli.jar -s http：// localhost：8080 –ssh -user username -i~ / .ssh / id_rsa build RTT / RTT-CI-Tools / RTT-CI-Tools-Distribute -s – p SLAVE_REGEX =从属名称
我收到的消息是

"WARNING: No header 'X-SSH-Endpoint' returned by Jenkins"

并且构建不会被触发.我也尝试过在jenkins-cli.jar命令中将-ssh替换为-http,

java -jar jenkins-cli.jar -s http：// localhost：8080 -http -auth用户名：60b3450a883a2519592af84cdcd0d224 build $CI_JOB -s -p SLAVE_REGEX = $SLAVEHOST

它触发了这项工作.再次无法启动从机,

如何解决这个问题

解决方法

我相信你的脚本中有些东西正在篡改标准输入.

您的脚本应该将整个未更改的stdin流传递给Jenkins代理进程.

通用解决方案

OP建立Jenkins会话的命令与我的不同,但无论如何,您应该将启动脚本分成3个主要部分：

设置：此部分不要篡改stdin或stdout.

建立Jenkins会话：java -jar jenkins-cli.jar …
