Jenkins通过ssh发布会显示错误“ jenkins.plugins.publish_over.BapPublisherException：无法添加SSH密钥。”

Question

为了通过ssh将jenkins与远程服务器连接，我在jenkins中安装了通过SSH插件发布。但是配置后，它将显示为jenkins.plugins.publish_over.BapPublisherException错误：无法添加SSH密钥。消息[无效私钥：[B @ 7934add]

最初，我在服务器上以jenkins用户身份登录为“ sudo su jenkins” 之后，我键入“ ssh-keygen”并给出密码短语的值，并给出詹金斯配置中的密钥路径。

我的密码短语是我在创建ssh-keygen时给出的值

我的密码/密码与我创建ssh-keygen时给出的值相同。我对这一点不正确

但是当我单击“测试配置”按钮时，我的所有配置都显示为“

Answer 1

密钥的路径应为私有密钥friend_ids的路径。

不是公用的id_rsa（确实是无效的...私钥）

创建SSH密钥对已生成：

• id_rsa.pub（私钥）
• /var/lib/jenkins/.ssh/id_rsa（公共密钥）

要打开SSH会话，需要将公用密钥复制到/var/lib/jenkins/.ssh/id_rsa.pub中的远程服务器上。
如果您具有远程ubuntu用户密码，则可以将ssh-copy-id command用作seen here：

/home/ubuntu/.ssh/authorized_keys

然后，您可以以ssh-copy-id -i /var/lib/jenkins/.ssh/id_rsa ubuntu@remoteserverip 的身份测试与sudo su jenkins的连接

Answer 2

您将需要在Jenkins服务器上以Jenkins用户身份创建公用/专用密钥，然后将公用密钥复制到要在目标服务器上进行部署的用户。

步骤1，以用户jenkins的身份在构建服务器上生成公钥和私钥

build1:~ jenkins$ whoami
jenkins
build1:~ jenkins$ ssh-keygen
Generating public/private rsa key pair.
Enter file in which to save the key (/var/lib/jenkins/.ssh/id_rsa): 
Created directory '/var/lib/jenkins/.ssh'.
Enter passphrase (empty for no passphrase): 
Enter same passphrase again: 
Your identification has been saved in /var/lib/jenkins/.ssh/id_rsa.
Your public key has been saved in /var/lib/jenkins/.ssh/id_rsa.pub.
The key fingerprint is:
[...] 
The key's randomart image is:
[...]
build1:~ jenkins$ ls -l .ssh
total 2
-rw-------  1 jenkins  jenkins  1679 Feb 28 11:55 id_rsa
-rw-r--r--  1 jenkins  jenkins   411 Feb 28 11:55 id_rsa.pub 
build1:~ jenkins$ cat .ssh/id_rsa.pub
ssh-rsa AAAlskdjfalskdfjaslkdjf... jenkins@myserver.com

第2步，将发布文件的内容粘贴到目标服务器上。

target:~ bob$ cd .ssh
target:~ bob$ vi authorized_keys (paste in the stuff which was output above.)
Make sure your .ssh dir has permissoins 700 and your authorized_keys file has permissions 644

第3步，配置Jenkins

In the jenkins web control panel, nagivate to "Manage Jenkins" -> "Configure System" -> "Publish over SSH"
Either enter the path of the file e.g. "var/lib/jenkins/.ssh/id_rsa", or paste in the same content as on the target server.
Enter your passphrase, server and user details, and you are good to go!

Answer 3

MacOS似乎使用了一种更新的技术来生成密钥。

使用-m PEM生成密钥为我解决了这个问题。

完整的呼叫是：ssh-keygen -t rsa -b 4096 -m PEM，然后按照Prakash所说的步骤进行操作。
