SSH KEYS认证方式改动
关于git pull origin sourceorgit push origin source,若出错：

fatal: Could not read from remote repository. 
Please make sure you have the correct access rights and the repository exists.

SSH keys不用动

gedit octopress/.git/config

把url = git@github.com:qiuhaidong/qiuhaidong.github.com.git
改为url = https://github.com/qiuhaidong/qiuhaidong.github.com.git

done.
pullorpush时或会报错，但不影响功能，多用几次就好了。
