背景：同一台电脑的public key同时添加到了github的两个账户，导致user1的仓库没法正常提交。
解决办法：为两个账户分别配置ssh key，配置~/.ssh/config文件（windows下也是这个路径，在git bash中可以识别~）
错误：
$ git push remote: Permission to user1/python.git denied to user2. fatal: unable to access 'https://github.com/user1/python.git/': The requested URL returned error: 403
环境：windows 7+ git bash
1、在github上删除两个账户的ssh key
2、生成两个ssh key
切换到ssh key的目录
$ cd ~/.ssh/
只需要修改文件名为user1_rsa, passphrase留空回车即可。
$ ssh-keygen -t rsa -C "user1" Generating public/private rsa key pair. Enter file in which to save the key (/c/Users/waston/.ssh/id_rsa): user1_rsa Enter passphrase (empty for no passphrase): Enter same passphrase again: Your identification has been saved in user1_rsa. Your public key has been saved in user1_rsa.pub. The key fingerprint is: SHA256:BJ5FGpGBCwM+Vw9769IACYHKoWD8gJURyYuSNOJQjUY user1 The key's randomart image is: +---[RSA 2048]----+ |=OEB +==o | |BBX =.=* | |@*=B o+o. | |*o+.o ... | |. . .S | | + | | . o | | . | | | +----[SHA256]-----+
同样方式生成user2_rsa
3、把user1_rsa_pub的内容上传到github后台, user2同样操作
https://help.github.com/articles/adding-a-new-ssh-key-to-your-github-account/
4、修改~/.ssh/config文件内容为：
#Default GitHub Host github.com HostName github.com User git IdentityFile ~/.ssh/user1_rsa IdentitiesOnly yes Host github2 HostName github.com User git IdentityFile ~/.ssh/user2_rsa IdentitiesOnly yes
5、添加你的ssh密钥到ssh-agent中
$ eval "$(ssh-agent -s)"
Agent pid 40672
$ ssh-add ~/.ssh/user1_rsa
Identity added: /c/Users/waston/.ssh/user1_rsa (/c/Users/waston/.ssh/user1_rsa)
$ ssh-add ~/.ssh/user2_rsa
Identity added: /c/Users/waston/.ssh/user2_rsa (/c/Users/waston/.ssh/user2_rsa)
6、测试
user1仓库测试:
cat@cat-pc MINGW64 /f/github/python (master) $ ssh -T github.com Hi user1! You've successfully authenticated, but GitHub does not provide shell access. cat@cat-pc MINGW64 /f/github/python (master) $ git push Everything up-to-date
$ ssh -T github2 Hi user2! You've successfully authenticated, but GitHub does not provide shell access. cat@cat-pc MINGW64 /h/z8 (master) $ git remote -v origin git@github.com:user2/z.git (fetch) origin git@github.com:user2/z.git (push) cat@cat-pc MINGW64 /h/z8 (master) $ git remote set-url origin git@github2:user2/z.git cat@cat-pc MINGW64 /h/z8 (master) $ git push Everything up-to-date
#提示文件不存在，检查下rsa文件名或者重新生成key
$ ssh -T github2
no such identity: /c/Users/waston/.ssh/user2_rsa: No such file or directory
Permission denied (publickey).
