配置gitlab/github/gitee多个ssh-key

gitlab的密钥配置

1. git bash执行下面命令生成ssh公钥和私钥对

   ssh-keygen -t rsa -C '你的邮箱' 一路回车 
   

2. 查看公钥内容：cat ~/.ssh/id_rsa.pub (~用户目录)
3. 配置远程仓库公钥：个人头像 -> settings -> SSH And GPG Key -> 点击 新增SSH Key按钮 -> 复制公钥
   

配置多个ssh-key

1. 为gitlab生成一对秘钥ssh key

   ssh-keygen -t rsa -C '[email protected]' -f ~/.ssh/gitlab-rsa
   

2. 为github生成一对秘钥ssh key

   ssh-keygen -t rsa -C '[email protected]' -f ~/.ssh/github-rsa
   

3. 添加私钥

   ssh-add ~/.ssh/gitlab-rsa 
   ssh-add ~/.ssh/github-rsa
   

   执行ssh-add时提示"Could not open a connection to your authentication agent"，可以现执行命令：

   ssh-agent bash
   # 确私钥列表
   ssh-add -l
   # 清空私钥列表
   ssh-add -D
   
   exit
   

   再运行ssh-add命令
4. 在~/.ssh下touch config，配置多个不同的ssh key

   # gitlab
   Host gitlab.com
   HostName gitlab.com
   PreferredAuthentications publickey
   IdentityFile ~/.ssh/gitlab-rsa 
   # github
   Host github.com
   HostName github.com
   PreferredAuthentications publickey
   IdentityFile ~/.ssh/github-rsa 
     ​
   # Host和HostName填写git服务器的域名，IdentityFile指定私钥的路径
   

5. 测试

   ssh -T -v git@[config配置的host值]
   ssh -T [email protected]
   ssh -T [email protected]
   ssh -T [email protected]
