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 git@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. git@111.11.111.11‘s password: Connection closed by 111.11.111.11 port 22 fatal: Could not read from remote repository. Please make sure you have the correct access rights 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 git@111.11.111.11:code.git Cloning into ‘code‘... git@111.11.111.11‘s password: Permission denied, please try again. git@111.11.111.11‘s password: Permission denied, please try again. git@111.11.111.11‘s password: git@111.11.111.11: Permission denied (publickey,gssapi-keyex,gssapi-with-mic,pas sword). fatal: Could not read from remote repository.

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 git@111.11.111.11:code.git Cloning into ‘code‘... warning: You appear to have cloned an empty repository.
