詹金斯为什么说"服务器在启动代理时拒绝了1个私钥"？

我成功地能够使用SSH连接到远程计算机,但是当我从Jenkins启动代理时,它会抛出以下错误:

ERROR: Server rejected the 1 private key(s) for user1 (credentialId:xxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx/method:publickey)

我可以使用建立从主机到节点机器的SSH连接user1,但是当我尝试使用user1jenkins 启动代理时,它拒绝私钥.有没有解决方案可以解决这个问题？

我按照以下步骤解决了这个问题:

从目标从节点的控制台

切换到"root"用户. sudo su

在家中添加jenkins用户“/var/lib/jenkins”.{注意:我保留我的主目录/var/lib/jenkins}: useradd -d /var/lib/jenkins jenkins

来自詹金斯大师

从主服务器上的Jenkins用户复制id_rsa.pub密钥.

cat /var/lib/jenkins/.ssh/id_rsa.pub

从目标从节点的控制台

为Jenkins用户创建authorized_keys文件.

mkdir /var/lib/jenkins/.ssh vi /var/lib/jenkins/.ssh/authorized_keys

将Jenkins master中的密钥粘贴到文件vim中.用":wq!"保存.
