我浏览了一些关于如何准备使用Capistrano的文档，其中包括Capistrano网站的“身份验证和授权”。
当我做这个命令时，所有人都在花哨
me@localhost $ ssh deploy@one-of-my-servers.com 'hostname; uptime'但是......当我遇到这个命令时
me@localhost $ ssh -A deploy@one-of-my-servers.com 'git ls-remote git@bitbucket.org:team/application.git我害怕了
Permission denied (publickey).我决定直接作为部署用户ssh到服务器并从那里尝试我的命令，但后来我被问到我的密码：
me@localhost:~$ ssh deployer@server.com ... bunch of logon information ... deployer@server:~$ git ls-remote git@bitbucket.org:team/application.git Enter passphrase for key '/home/deployer/.ssh/id_rsa':我输入了密码并得到了bitbucket的回复。 现在我不明白为什么我被问到我的密码短语，因为ssh-agent应该加载我的身份，并且所有人应该对deployer和bitbuckt都很好。 我决定检查ssh-agent是否通过运行加载了我的身份
ssh-add -l但后来我得到了
Could not open a connection to your authentication agent.什么？ 好吧，然后我启动了ssh-agent并确保通过执行此操作来加载我的身份
deployer@server:~$ eval "$(ssh-agent)" Agent pid 30113 deployer@server:~$ ssh-add -l The agent has no identities. deployer@server:~$ ssh-add Enter passphrase for /home/deployer/.ssh/id_rsa: Identity added: /home/deployer/.ssh/id_rsa (/home/deployer/.ssh/id_rsa) deployer@server:~$ ssh-add -l 2048 6c:87:f9:e1:71:75:0d:1c:cf:8d:d8:a8:06:fc:70:e7 /home/deployer/.ssh/id_rsa (RSA)现在我可以从bitbucket做我的远程列表，而不必输入我的密码
deployer@server:~$ git ls-remote git@bitbucket.org:team/application.git f25db5c4691531c8ad27882c74d9668de66f795f HEAD 97a68f4f6cbffd0c320b37891ffdda57931146f4 refs/heads/deployer f25db5c4691531c8ad27882c74d9668de66f795f refs/heads/master deployer@server:~$现在我很高兴退出服务器并再次尝试从我的本地机器
deployer@server:~$ exit logout Connection to server.com closed. me@localhost:~$ ssh deployer@server.com 'git ls-remote git@bitbucket.org:team/application.git' Permission denied (publickey). fatal: The remote end hung up unexpectedly??? 我的问题就在于......现在你能看到我哪里出错吗？
I went through the a few documentation on how to prepare for using Capistrano and among those was the "authentication and authorization" from the Capistrano web site.
All was going dandy when I did this command
me@localhost $ ssh deploy@one-of-my-servers.com 'hostname; uptime'but.. when I come across this command
me@localhost $ ssh -A deploy@one-of-my-servers.com 'git ls-remote git@bitbucket.org:team/application.gitI got a dreaded
Permission denied (publickey).I decided to ssh to the server directly as the deployment user and try my command from there but then I was asked for my passphrase:
me@localhost:~$ ssh deployer@server.com ... bunch of logon information ... deployer@server:~$ git ls-remote git@bitbucket.org:team/application.git Enter passphrase for key '/home/deployer/.ssh/id_rsa':I entered the passphrase and got the response from bitbucket. Now I didn't understand why I was asked for my passphrase becuase the ssh-agent should have my identy loaded and all should be good with deployer and bitbuckt. I decided to check if ssh-agent had my identity loaded by running
ssh-add -lbut then I got
Could not open a connection to your authentication agent.what? ok, then I started the ssh-agent and made sure my identity was loaded by doing this
deployer@server:~$ eval "$(ssh-agent)" Agent pid 30113 deployer@server:~$ ssh-add -l The agent has no identities. deployer@server:~$ ssh-add Enter passphrase for /home/deployer/.ssh/id_rsa: Identity added: /home/deployer/.ssh/id_rsa (/home/deployer/.ssh/id_rsa) deployer@server:~$ ssh-add -l 2048 6c:87:f9:e1:71:75:0d:1c:cf:8d:d8:a8:06:fc:70:e7 /home/deployer/.ssh/id_rsa (RSA)and now I could do my remote listing from bitbucket just fine without having to enter my passphrase
deployer@server:~$ git ls-remote git@bitbucket.org:team/application.git f25db5c4691531c8ad27882c74d9668de66f795f HEAD 97a68f4f6cbffd0c320b37891ffdda57931146f4 refs/heads/deployer f25db5c4691531c8ad27882c74d9668de66f795f refs/heads/master deployer@server:~$now I was happy and logged out of the server and tried again from my local machine
deployer@server:~$ exit logout Connection to server.com closed. me@localhost:~$ ssh deployer@server.com 'git ls-remote git@bitbucket.org:team/application.git' Permission denied (publickey). fatal: The remote end hung up unexpectedly??? There lies my problem... now can you see where I'm going wrong?
最满意答案
您可以登录一次以启动ssh-agent并将密钥（ssh-add）加载到代理中。 将ssh-agent的输出保存在某个文件中。
当您远程登录git时，使用保存的信息通过bashrc或其他启动脚本设置SSH_AUTH_SOCK和SSH_AGENT_PID。 您不需要新的ssh-agent。 你需要指向已经拥有密钥的那个。
You can login once to start the ssh-agent and load your keys (ssh-add) into the agent. Save the output of ssh-agent in some file.
When you login remotely for git purpose, set SSH_AUTH_SOCK and SSH_AGENT_PID through your bashrc or some other startup script using the saved info. You do not want a new ssh-agent. You need to point to the same one that already has the keys.
