增加admin管理后台，配置方法很简单：

1. Setup hexo & create a blog

这一步在之前的步骤中其实已经执行了

npm install -g hexo
cd ~/
hexo init my-blog
cd my-blog
npm install

2. Install the admin & start things up

注意一定要进入blog目录再执行

npm install --save hexo-admin
hexo server -d

open http://localhost:4000/admin/

3. Profit!

The UI should be pretty discoverable – let me know if you can’t find something.

已经已经可以打开了：http://localhost:4000/admin

4. Password protection

If you’re using Hexo admin on your live server, you want some password protection. To enable this, you just add a few config variables to your hexo _config.yml:

admin:
  username: myfavoritename
  password_hash: be121740bf988b2225a313fa1f107ca1
  secret: a secret something

将上述配置增加到 _config.yml:中，之后登陆admin的时候就开始需要输入用户名和密码

5. Custom post metadata

To add and edit your own post metadata with the admin interface, add the metadata variable and your custom variables to your hexo _config.yml:

metadata:
  author_id: defaultAuthorId
  language:

You can provide default values that will be used to initialize the metadata of a new post.
