gitlab ssh-key 등록방법

gitlab의 저장소에 외부에서 push, pull로 접근할때는, 프로젝트에 push/pull권한을 가진 user에게 등록된 public 키와 외부에 있는 private키의 일치여부를 확인해 접근한다. 

1. 키를 생성하는 방식과 public 키를 gitlab에 등록하는 방식은 아래 링크를 따라한다.

https://gitlab.com/help/ssh/README

2. ssh private key가 .ssh 폴더에 저장되어 있더라도 연결이 안되는 경우가 있다.(맥의 경우). 그럴 경우 하단 링크를 따라한다.

https://help.github.com/articles/generating-a-new-ssh-key-and-adding-it-to-the-ssh-agent/

3. 키가 제대로 등록되었는지 확인하는 방법은 

ssh-add -l

을 입력하면 가능하다.

Could not open a connection to your authentication agent

Could not open a connection to your authentication agent.

Scenario: Type ssh-add id_rsa

Received Error message: "Could not open a connection to your authentication agent."

Likely that settings for ssh-agent are not set.

$ ssh-agent

SSH_AUTH_SOCK=/tmp/ssh-kGfnsjzf1291/agent.1291; export SSH_AUTH_SOCK;

SSH_AGENT_PID=1292; export SSH_AGENT_PID;

echo Agent pid 1292;

SETTING IT UP:

$ eval `ssh-agent`

SSH_AUTH_SOCK=/tmp/ssh-UxhvZUGE1293/agent.1293; export SSH_AUTH_SOCK;

SSH_AGENT_PID=1294; export SSH_AGENT_PID;

echo Agent pid 1294;

$ ssh-add

Enter passphrase for /home/ubuntu/.ssh/id_rsa: 

Identity added: /home/ubuntu/.ssh/id_rsa (/home/ubuntu/.ssh/id_rsa)

ssh_options[:forward_agent] = true on OSX Lion

On OSX Lion you may encounter problems with doing a capistrano deploy with forward agent, giving you a status code of 32768 and a "Repository not found"

First off forward agent is disabled by default on Lion, you can enable it by editing your /etc/ssh_config file

sudo nano /etc/ssh_config

and changing

# ForwardAgent no

to

ForwardAgent yes

perform a reboot, then add your necessary keys into the keychain via

ssh-add -K ~/.ssh/mydeploykey

now you should be able to do a deploy via forward agent on OSX Lion without any problems, note some users have been able to do this without the ssh_config change and others have to.
