Steps

1. node.js&&git
2. $ npm install -g hexo
3. hexo init//(some folder ,for example:D:/hexo)
   npm install
   Local Test:
   hexo generate
   hexo server
   then u can goto http://localhost:4000
4. have a github id ,and new a repository(like this youName.github.io )
5. 编辑_config.yml(在D:\hexo下)
   deploy:
   type: github
   type: git //我用这个
   repository: https://github.com/youName/youName.github.io.git
   repository: git@github.com:youName/youName.github.io.git //我用的这个
   branch: master
   注意：:后面一定加个空格!
   5.
   $ npm install hexo-deployer-git –save
   hexo generate
   hexo deploy
   参照：https://hexo.io/docs/deployment.html
   最新版的hexo貌似要在第一次hexo d的之前，要有npm install hexo-deployer-git –save
   6.
   goto：https://yourName.github.io
   it works!hah~
   7.
   some benefits
   hexo g == hexo generate
   hexo d == hexo deploy
   hexo s == hexo server
   hexo n == hexo new
6. clone themes
   进入hexo官网，预览自己想要的主题， https://github.com/hexojs/hexo/wiki/Themes
   for example:
   D:/hexo/themes ,git bash
   git clone https://github.com/hexojs/hexo-theme-light.git
   cd themes/light
   git pull
