检查是否能连接成功

ssh -T git@github.com

提示错误

ssh: connect to host github.com port 22: Connection timed out

在C盘/用户/用户名/.ssh中创建 config文件（没有任何后缀）

编辑该文件，输入

# github
Host github.com
# github邮箱
User xxxxxx@qq.com
HostName ssh.github.com
PreferredAuthentications publickey
# 指定ssh私钥文件
IdentityFile ~/.ssh/github
# 修改连接端口
Port 443

再次检查是否能正常连接

ssh -T git@github.com

会出现以下提示，输入 yes 回车即可

The authenticity of host '[ssh.github.com]:443 ([192.30.255.123]:443)' can't be established.

Are you sure you want to continue connecting (yes/no)? yes
