Git多SSH账号管理

1. 生成本地密钥

生成github公私钥:

ssh-keygen -t rsa -C "[e-mail]" -f ~/.ssh/id_rsa_github

生成公司gitlab公私钥:

ssh-keygen -t rsa -C "[e-mail]" -f ~/.ssh/id_rsa_gitlab

如果提示ssh-keygen找不到：

ssh-keygen: command not found

先安装openssh-clients（CentOS）：

yum -y install openssh-clients

生成结果如下图所示，以pub结尾的就是公钥文件：

2. 添加私钥

ssh-add ~/.ssh/id_rsa_githubssh-add ~/.ssh/id_rsa_gitlab

如果系统提示：could not open a connection to your authentication agent
则需要执行一下命令：

ssh-agent bash

3. 添加配置文件

创建配置文件：

touch ~/.ssh/config

添加配置内容：

Host github    HostName github.com    User git    IdentityFile ~/.ssh/id_rsa_githubHost gitlab    HostName gitlab.com    User git    IdentityFile ~/.ssh/id_rsa_gitlab

4. 上传公钥

复制公钥，在Gitlab->Profile Settings->SSH-Keys上添加：

Windows:

clip < ~/.ssh/id_rsa_gitlab.pub

Mac:

pbcopy < ~/.ssh/id_rsa_gitlab.pub

GNU/Linux (requires xclip):

xclip -sel clip < ~/.ssh/id_rsa_gitlab.pub

5. 测试

ssh -T [e-mail]
