git使用ssh配置多个账号

生成本地密钥

假如我们有2个git账号，分别来自github和coding，进入目录C:\Users\Administrator\.ssh

首先生成github密钥，注意区分密钥文件名

1
ssh-keygen -t rsa -C "email@gmail.com" -f id_rsa_github

生成coding密钥

1
ssh-keygen -t rsa -C "email@qq.com" -f id_rsa_coding

生成结果如下所示，以pub结尾的就是公钥文件

-rw-------+ 1 Administrator None 1679 Dec 19 12:17 id_rsa_coding
-rw-r--r--+ 1 Administrator None  397 Dec 19 12:17 id_rsa_coding.pub
-rw-------+ 1 Administrator None 1679 Dec 17 10:29 id_rsa_github
-rw-r--r--+ 1 Administrator None  399 Dec 17 10:29 id_rsa_github.pub

添加私钥

1
2
ssh-add id_rsa_github
ssh-add id_rsa_coding

如果返回could not open a connection to your authentication agent, 则先执行以下命令

1
ssh-agent bash

创建配置文件

在.ssh目录下新建配置文件config

1
touch config

并添加以下配置内容:

# *配置github.com*
Host github.com              
    HostName github.com
    IdentityFile C:\\Users\\Administrator\\.ssh\\id_rsa_github
    PreferredAuthentications publickey
    User git

# 配置git.coding.net 
Host coding.net
    HostName coding.net
    IdentityFile C:\\Users\\Administrator\\.ssh\\id_rsa_coding
    PreferredAuthentications publickey
    User git

上传公钥

以github为例, 进入Settings -> SSH and GPG keys, 点击”New SSH key”, 并将id_rsa_github.pub文件里的内容复制到Key中

测试结果

1
ssh -T git@github.com

如果返回以下结果表示配置成功

1
Hi xxx! You've successfully authenticated, but GitHub does not provide shell access.
