git配置ssh密钥

git配置ssh密钥

如果主机（当前登录用户）之前没有git账号，即添加第一个git账号，并配置ssh密钥时，

按照如下的步骤：

1 cd  ~/.ssh

2 ssh-keygen -t rsa -C 'liulian@gmail.com'

3 cat id_rsa.pub

4 拷贝公钥到git服务器上

5 测试：git clone
git@git.host.com:liulian/mahout-0.9-custom.git

 

附加信息：

1

ssh-keygen -t rsa -C 'liulian@gmail.com'

Generating public/private rsa key pair.

Enter file in which to save the key(/data/home/liulian/.ssh/id_rsa):

Enter passphrase (empty for no passphrase):                （输入密码）

Enter same passphrase again:                               （再次输入密码）

Your identification has been saved in/data/home/liulian/.ssh/id_rsa.

Your public key has been saved in/data/home/liulian/.ssh/id_rsa.pub.

The key fingerprint is:

72:d2:d7:6e:35:68:e2:d8:78:5d:a6:99:4e:df:9e:0e liulian@gmail.com

The key's randomart image is:

git clone git@git.host.com:liulian/mahout-0.9-custom.git

Initialized empty Git repository in/data/home/liulian/project/mahout/mahout-0.9-custom/mahout-0.9-custom/.git/

The authenticity of host 'git.host.com(10.150.144.21)' can't be established.

Are you sure you want to continue connecting(yes/no)? yes

如果主机（当前登录用户）之前已配置过一个git账号，再配置新的git账号时，按以下步骤。

 

1 cd ~/.ssh

2 生成密钥

ssh-keygen -t rsa -C 'liulian@gmail.com'

Generating public/private rsa key pair.

Enter file in which to save the key(/root/.ssh/id_rsa): linger_git

Enter passphrase (empty for no passphrase):09388296

3 查看公钥，并拷贝到git服务器上

cat linger_git.pub

vi config

Host git.host.com ##可以随意命名，链接时使用这个名字 

HostName git.host.com

User git

# Port 22 

IdentityFile ~/.ssh/linger_git

 

5 测试

git clone git@git.host.com:liulian/weibo.git

Initialized empty Git repository in/root/liulian/git/weibo/weibo/.git/

Enter passphrase for key '/root/.ssh/linger_git':

remote: Counting objects: 106, done.

remote: Compressing objects: 100% (80/80), done.

remote: Total 106 (delta 23), reused 103 (delta 23)

Receiving objects: 100% (106/106), 190.24 KiB,done.

Resolving deltas: 100% (23/23), done.

 

PS:如果主机当前登录用户，没有设置过任何git账号，记得用上面的方法1，我曾经试过在这种情况直接用上面的方法2，竟然不行，后来用方法1就行了。
