Question

我现有的jenkins主从连接断了。我尝试通过scp命令建立连接。

主人：

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，收到以下错误。

我甚至尝试过以下帖子，但没有得到解决方案。

Answer 1

sudo chmod -R 777 /home/jenkins

Answer 2

就像你有一个用户名＆＃34; jenkins＆＃34;和家庭目录是＆＃34; / home / jenkins＆＃34; 您必须将此主目录放在节点配置中，请参阅＆＃34;远程根目录：/ home / jenkins＆＃34; 它解决了我的问题..特别是对于AWS-ec2而且没有在主目录上设置完全权限，它会影响它。

无法将slave.jar复制到＆＃39; / home / jenkins＆＃39;在奴隶
