Jenkins - Unable to git clone from slave node. SSH keys
提问by nonshatter
I have just set up my first Jenkins slave. I run the build, and I hit problems with the SSH keys. The master Jenkins server is running under the user 'jenkins'. I have set up the SSH keys such that I can SSH from the master to the slave without a password.
我刚刚建立了我的第一个 Jenkins slave。我运行构建，但遇到了 SSH 密钥问题。Jenkins 主服务器在用户“jenkins”下运行。我已经设置了 SSH 密钥，这样我就可以在没有密码的情况下从主站到从站进行 SSH 连接。
e.g. From the master:
例如来自主人：
jenkins@master:~$ ssh slave
Last login: Tue Apr 17 10:30:22 2012 from masterjenkins.com
$ whoami
jenkins
So that proves that the slave node is also running under the 'jenkins' user. (I have copied the public ssh key from the jenkins@slave to the remote git server). And I am able to issue the git clone manually from the slave, but when I kick off the build from the master I get these kinds of messages:
所以这证明从节点也在'jenkins'用户下运行。（我已将公共 ssh 密钥从 jenkins@slave 复制到远程 git 服务器）。而且我可以从从站手动发出 git clone，但是当我从主站开始构建时，我收到以下类型的消息：
ERROR: Error cloning remote repo 'origin' : Could not clone git@host:abc
hudson.plugins.git.GitException: Could not clone git@host:abc
Caused by: hudson.plugins.git.GitException: Error performing command: git clone --progress -o origin git@host:abc /var/lib/jenkins/workspace/abc_build
Command "git clone --progress -o origin git@host:abc /var/lib/jenkins/workspace/abc_build" returned status code 128: Initialized empty Git repository in /var/lib/jenkins/workspace/abc_build/.git/
Host key verification failed.
fatal: The remote end hung up unexpectedly
Caused by: hudson.plugins.git.GitException: Command "git clone --progress -o origin git@host:abc /var/lib/jenkins/workspace/abc_build" returned status code 128: Initialized empty Git repository in /var/lib/jenkins/workspace/abc_build/.git/
Host key verification failed.
fatal: The remote end hung up unexpectedly
Trying next repository
ERROR: Could not clone repository
FATAL: Could not clone
So it is still hinting that my SSH keys are not set up correctly. Can anyone tell me what keys I need to copy where?
所以它仍然暗示我的 SSH 密钥设置不正确。谁能告诉我需要复制哪些密钥？
Many thanks, ns
非常感谢， ns

Based on the clone URL it appears you are mixing up two different authentication methods. You are trying to SSH into host as the user gitnot jenkins. Typically when you host your own GIT repositories and clone with git@servername:reponame you use something like gitolite.
根据克隆 URL，您似乎混合了两种不同的身份验证方法。您正在尝试使用SSH连接主机的用户git没有jenkins。通常，当您托管自己的 GIT 存储库并使用 git@servername:reponame 进行克隆时，您会使用类似 gitolite 的东西。
Did you set anything up like gitolite?
你有没有设置像gitolite这样的东西？
Try ssh'ing like this instead as the jenkins user.
以 jenkins 用户的身份尝试像这样 ssh'ing。
ssh git@slave
Then see what that returns. This is an SSH more in line with the git@host:abcyou are doing.
然后看看返回什么。这是一个更符合git@host:abc你正在做的SSH 。
If you didnt setup anything else on your server machine, then change your clone url to jenkins@host:pathtorepo
如果您没有在服务器计算机上设置任何其他内容，请将您的克隆 url 更改为 jenkins@host:pathtorepo
Update
更新
/home/git/.ssh/authorized_keys
/home/git/.ssh/authorized_keys
Should have an entry like this: (This is all on ONE line)
应该有这样的条目：（这都在一行上）
# gitolite start
command="/home/git/bin/gl-auth-command jenkins",no
-port-forwarding,no-X11-forwarding,no-agent-forwarding,no-pty ssh-rsa AAAAB3NzaC1yc2EAAAABJQAAAIEAt3+od84Gc9NBVrVb3MKjekHcBDwXXONnVYMNVpuRadoz/FPJTkOIxozKVPJDPI670O252giYpF59sOKqAJL0xEVUrhq8cDFuFwQsSAp0ed1kp/GRxx+pwytL58rcVJEHAy2DkD1z5HlNaZyvIxQyfLTnYfuL1Hx6Qe7dal7mXO0= keycomment
# gitolite end
Add repository permissions to jenkins in gitolite: (You may have to clone on the same machine that is hosting your repositories, as the gitolite user)
在 gitolite 中向 jenkins 添加存储库权限：（您可能必须在托管存储库的同一台机器上克隆，作为 gitolite 用户）
git clone git@host:gitolite-admin
cd gitolite-admin
cd conf
vi gitolite.conf
Now find the entry for 'abc' or add one if it doesn't exist
现在找到“abc”的条目，如果不存在则添加一个
repo abc
RW+ = jenkins
Now commit and push changes
现在提交并推送更改
git commit -a -m "Adding user jenkins to repo abc"
git push
Now do your ssh git@hostagain to see if gitolite tells you about your new permissions.
现在再做ssh git@host一次，看看 gitolite 是否告诉你你的新权限。
