• 发送公钥

$ cat /c/Users/lxr/.ssh/id_ed25519.pub
ssh-ed25519 AAAAC3NzaC1lZDI1NTE5AAAAIOx77t5o475 Administrator@PC-20230304LWJY

服务端

• 添加公钥

$ cat id_ed25519.pub >> ~/.ssh/authorized_keys

如果服务端是Windows

修改文件 C:\ProgramData\ssh\sshd_config

确保以下2条没有被注释
PubkeyAuthentication yes
AuthorizedKeysFile	.ssh/authorized_keys

确保以下2条有注释掉
#Match Group administrators
#       AuthorizedKeysFile __PROGRAMDATA__/ssh/administrators_authorized_keys

Git仓库

推荐裸仓库

git init -bare sample.git

如果仓库不是裸仓库

git init sample

git config receive.denyCurrentBranch ignore

如果Git仓库在Windows

修改注册表，修改openssh默认shell

git clone lxr@192.168.0.20:D:/WORK/2_gitrepo/sample.git
