无法将 slave.jar 复制到 slave 上的“/home/jenkins”

Question

我现有的詹金斯主从连接坏了。我尝试通过 scp 命令建立连接。

在主人身上：

scp ~/ .ssh/id_rsa.pub jenkins@<my_slave_machine>:/tmp

在奴隶上：

•   ssh-keygen –b 2048 –t rsa
•   Press enter for " Enter file in which to save the key (/home/jenkins/.ssh/id_rsa) : " 
•   Press enter for  " Enter passphrase (empty for no passphrase):" 
•   Press enter for  " Enter same passphrase again:"
•   cd .ssh/
•   touch authorized_keys
•   chmod 600 authorized_keys
•   cat /tmp/id_rsa.pub >> authorized_keys

尝试从 UI 连接后，出现以下错误。

我什至尝试了以下帖子，但没有得到解决方案。

• Jenkins Slave Permission Denied while copying slave.jar
• https://issues.jenkins-ci.org/browse/JENKINS-26259
• https://issues.jenkins-ci.org/browse/JENKINS-22651
• Jenkins slave set-up - Both Master and Slave Nodes are Linux machines

您似乎以名为“dx00926”的用户身份连接到此服务器。这个错误最简单的解释是远程系统上的这个“dx00926”用户没有在/home/jenkins目录下创建文件的权限，或者那里有一个名为“/home/jenkins/slave.jar”的文件并且此用户无权覆盖其内容。

要么修改 /home/jenkins 目录的权限以允许 dx00926 在那里创建文件，要么使用 确实 有权在那里创建文件的用户连接到远程系统。

Answer 2

如果你有一个用户名“jenkins”并且主目录是“/home/jenkins” 您必须将此主目录放在节点配置中，请参阅“远程根目录：/home/jenkins” 它解决了我的问题.. 特别是对于 AWS-ec2 并且不要对主目录设置完全权限，它会影响它。

Answer 3

我遇到了这个错误，我尝试了上述解决方案，但我能够解决它的唯一方法是删除节点，删除 /opt/jenkins 文件夹，然后重新创建文件夹和节点。之后它工作正常。

Answer 4

sudo chmod -R 777 /home/jenkins
