同步仓库并解决403报错
这时候对本地仓库和github进行同步
# git push -u origin master
error: The requested URL returned error: 403 Forbidden while accessing https://github.com/user/test.git/info/refs
fatal: HTTP request failed
提示403 Forbidden！
打开开关看详细日志

可以看到上面红色加粗的文字（The requested URL returned error: 401 Authorization Required），是权限问题导致的，可以修改.git/config文件追加用户名和密码：
1）编辑.git/config文件
2）在[remote “origin”]下找到找到url变量
3）修改url = https://github.com/user/test.git，修改为url = ssh://git@github.com/user/test.git，修改完了保存
4）通过git push origin master进行同步，已经可以成功了
