解决github 22端口被占用，改用443端口1.1 22端口被占用 ssh: connect to host git

在git push时突然出现以下报错

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.

解决方法：修改生成的rsa所在地址~/.ssh下面的config文件,如果没有的话就自己手动新建一个填入以下信息

Host github.com
HostName ssh.github.com  # 这是最重要的部分
User git
Port 443
PreferredAuthentications publickey
IdentityFile ~/.ssh/id_rsa
