git遇到的常见问题

1) 重新ssh-keygen -t rsa -C "xxxx@xxx.com" 后链接不上

debug 过程:

1.用vim打开id_isa.pub复制到gihub 报错 格式不对 ---->用 cat 或者 gedit打开

2.ssh git@github.com 失败:报 Permission publickey(denies) -----> ssh -T -v git@github.com 在日志中发现:

debug1: Next authentication method: publickey

debug1: Trying private key: /home/sunny/.ssh/id_dsa

debug1: Trying private key: /home/sunny/.ssh/id_ecdsa

debug1: No more authentication methods to try.

它一直在找id_dsa,id_ecdsa两个私钥,
!!!!而ssh-keygen生成的是id_isa ,id_isa.pub .所以cp id_isa id_dsa
即可链接成功
