CentOS 7.3执行git clone时卡在正克隆到'XXXXXX'

# git clone git@github.com:XXX/XXXXXX.git 正克隆到 'XXXXXX'... ssh: connect to host github.com port 22: Connection timed out fatal: Could not read from remote repository.

Please make sure you have the correct access rights and the repository exists.

错误：到github.com:22连接超时

原因：22端口无法使用

解决方法：修改为443端口

# sudo vim ~/.ssh/config

Host github.com User username@gmail.com Hostname ssh.github.com PreferredAuthentications publickey IdentityFile ~/.ssh/id_rsa Port 443

# git clone git@github.com:MocyRee/XXXXXX.git 正克隆到 'XXXXXX'... The authenticity of host '[ssh.github.com]:443 ([192.30.253.122]:443)' can't be established.
