一、问题现象：
配置Jenkins使用git，连接github，验证失败。日志如下：
Failed to connect to repository : Command "git ls-remote -h
git@github.com:***********/game-of-life.git HEAD" returned status
code 128:
stdout:
stderr: Host key verification
failed.
fatal: The remote end hung up unexpectedly
二、解决办法：
***Set
up SSH for Git on Linux***
Step 1. Ensure you
have an SSH client installed
# ssh -v
Step 2. Set up your default
identity
1)Open a terminal in your local
system.
2)Enter ssh-keygen at the command
line.
The command prompts you for a file
where you want to save the key. If the .ssh directory doesn't
exist, the system creates one for you.
# ssh-keygen
3)Press the Enter or Return key to
accept the default location.
4)Enter and re-enter a passphrase
when prompted.
Step 3. Start the ssh-agent and
load your keys
1)Open a terminal window and enter
the ps -e | grep ssh-agent command to see if the agent is
running:
# ps -ef | grep
ssh-agent
2)If the agent isn't running, start
it manually with the following command:
# ssh-agent /bin/bash
# ps -ef | grep
ssh-agent
3)Load your new identity into the
ssh-agent management program using the ssh-add command.
# ssh-add ~/.ssh/id_rsa
Identity added: /root/.ssh/id_rsa
(/root/.ssh/id_rsa)
4)Use the ssh-add command to list
the keys that the agent is managing.
# ssh-add -l

64:8f:33:66:86:6d:4b:8c:c1:d8:72:81:b1:8e:19:7e /root/.ssh/id_rsa
(RSA)
Step 4. Install the public key on
your Bitbucket account
1)Open a browser and log into
Bitbucket.
2)Choose avatar > Manage Account
from the application menu. The system displays
the Account settings page.
3)Click SSH keys.
The SSH Keys page displays. It shows a list of
any existing keys. Then, below that, a dialog for labeling and
entering a new key.
4)Back in your terminal window, copy
the contents of your public key file.For example, in Linux you can
cat the contents.
cat ~/.ssh/id_rsa.pub
5)Back in your browser, enter a
Label for your new key, for example, Default public key.
6)Paste the copied public key into
the SSH Key field.
7)Press Add key. The system adds the
key to your account. Bitbucket sends you an email
to confirm addition of the key.
Step 5. Change your repo from
HTTPS to the SSH protocol
The URL you use for a repo depends
on which protocol you are using, HTTPS or SSH.
The Bitbucket repository Overview
page has a quick way for you to see these URLS for your
game-of-life repo.
on the repo's Overview page look for
the Clone button.
