gitlab 添加 ssh key

2022-10-17

ssh key 配置

1.
# 一路回车(-C 参数是你的邮箱地址)
ssh-keygen -t rsa -C 'xxx@xxx.com'

2.
# 然后打开~/.ssh/id_rsa.pub文件(~表示用户目录，比如我的windows就是C:\Users\Administrator)，复制其中的内容

3.
# 如下密钥框中，填写 id_rsa.pub 内容；

4. 
# 接下来就是测试拉取；ssh 密钥添加之后，使用 ssh方式拉取不用填写密码；
[egrade-hk@rancher tmp]$ git clone git@gitlab-hk.xxxxx.com:root/xxxxxx.git
Cloning into 'egradehkeks'...

配置多个 ssh key

  1. 为公司生成一对秘钥ssh key

    ssh-keygen -t rsa -C 'yourEmail@xx.com' -f ~/.ssh/gitlab-rsa

  2. 为github生成一对秘钥ssh key

    复制ssh-keygen -t rsa -C 'yourEmail2@xx.com' -f ~/.ssh/github-rsa

  3. 在~/.ssh目录下新建名称为config的文件（无后缀名）。用于配置多个不同的host使用不同的ssh key，内容如下：

# gitlab
Host gitlab.com
    HostName gitlab.com
    PreferredAuthentications publickey
    IdentityFile ~/.ssh/gitlab_id-rsa
# github
Host github.com
    HostName github.com
    PreferredAuthentications publickey
    IdentityFile ~/.ssh/github_id-rsa

# 配置文件参数
# Host : Host可以看作是一个你要识别的模式，对识别的模式，进行配置对应的的主机名和ssh文件
# HostName : 要登录主机的主机名
# User : 登录名
# IdentityFile : 指明上面User对应的identityFile路径

按照上面的步骤分别往gitlab和github上添加生成的公钥gitlab_id-rsa.pub和github_id-rsa.pub

OK，大功告成，再次执行git命令验证是不是已经不需要再次验证权限了。

再次查看~/..ssh目录下的文件,会有gitlab_id-rsa、gitlab_id-rsa.pub和github_id-rsa、github_id-rsa.pub四个文件
