git连接报错：Permission denied (publickey,gssapi-keyex,gssapi-with-mic,password)

Posted 2021-02-13 不想下火车的人

　　在Linux上已经安装过git了，本机（windows）想连接，通过git bash敲了下clone命令提示没权限：

$ git clone [email protected]111.11.111.11:code.git
Cloning into ‘code‘...
The authenticity of host ‘111.11.111.11 (111.11.111.11)‘ can‘t be established.
ECDSA key fingerprint is SHA256:7jmL7Nrr9zJ7psJd3Zcfr4UckRNOMkgwK/ae9dsCgaw.
Are you sure you want to continue connecting (yes/no)? yes
Warning: Permanently added ‘116.62.136.56‘ (ECDSA) to the list of known hosts.

fatal: Could not read from remote repository.

and the repository exists.

　　第一次连接失败很正常，毕竟没有设置账号信息，但第二次连接敲了自己刚设置的密码，竟然一直提示没权限

$ git clone [email protected]111.11.111.11:code.git

　　蒙圈了，密码对的啊。看下日志：

　　接着看一下我的公钥：

$ cat /c/Users/wulf/.ssh/id_rsa.pub
ssh-rsa AAAAB3NzaC1yc2EAAAADAQABAAACAQCf20s0rabgMRn8CCCCC/+VC/wS5x/dvIYoG+TP23bHWn9gD/AXizrkds5geX9AG90oVRqf+RfTvLFlaNMrzK

　　公钥太长，随便贴了点。后来才发现linux上的git根本不认识你，因为你有的是你自己的密码，人家那还没有你的公钥呢，得去它那里设置一下。

　　登陆linux下的111.11.111.11，把上面那段公钥丢到authorized_keys里：

vi /home/git/.ssh/authorized_keys

　　保存后再去本地连下，ok了：

$ git clone [email protected]111.11.111.11:code.git
Cloning into ‘code‘...
