Github 访问时出现Permission denied (public key)

一. 发现问题:

  使用 git clone 命令时出现Permission denied (public key) 。

二. 解决问题:

  1、首先尝试重新添加以前生成的key,添加多次,仍然不起作用。

  2、使用命令 ssh -v git@github.com测试,最后几行结果如下:   

    debug1: Authentications that can continue: publickey
    debug1: Next authentication method: publickey
    debug1: Trying private key: /home/gr/.ssh/id_rsa
    debug1: Trying private key: /home/gr/.ssh/id_dsa
    debug1: Trying private key: /home/gr/.ssh/id_ecdsa
    debug1: No more authentication methods to try.
    Permission denied (publickey).

  3、分析:尝试了3个private key,但都没有成功,最后是导致Permission denied.

  4、查看我的密钥, ls ~/.ssh/ :

    bajie  bajie.pub  known_hosts    

  5、发现我的id_rsa文件我命令为bajie, 所以根本没有使用它。同时可以使用如下命令查看密钥列表:

    ssh-add -l

  6、上面命令的密钥列表为空,所以要添加我的密钥,使用命令:

    gr@grpc:~/workspace/git/home$ ssh-add ~/.ssh/bajie

    Enter passphrase for /home/gr/.ssh/bajie:
    Identity added: /home/gr/.ssh/bajie (/home/gr/.ssh/bajie)

  7、再次查看,如下,添加成功:

    gr@grpc:~/workspace/git/home$ ssh-add -l

    2048 63:c5:d8:6c:a0:0c:a8:9c:26:d8:f8:95:de:29:04:eb /home/gr/.ssh/bajie (RSA)

  8、再使用ssh -v git@github.com测试连接,可以看到验证通过:

    debug1: Authentications that can continue: publickey
    debug1: Next authentication method: publickey
    debug1: Offering RSA public key: /home/gr/.ssh/bajie
    debug1: Server accepts key: pkalg ssh-rsa blen 279
    debug1: Authentication succeeded (publickey).
    Authenticated to github.com ([192.30.252.129]:22).

  9、最后git clone项目成功。
