好好学Hexo：Hexo环境搭建

1. 前言

重装了系统，Hexo没法使用了。第一次安装的时候，没有做任何记录，这次刚好记录一下。

2. hexo官网

3. 下载安装git

git官方下载地址：http://git-scm.com/download/
分享一个14年版本：http://yunpan.cn/cwqWapRIyFWrA 访问密码 8f1b
下载好之后，双击安装，一路next即可。唯一需要注意的是，在Select Components界面，点选Simple context menu。

4. 下载安装Node.js

Node.js官方下载地址：https://nodejs.org/ ，Current version: v0.12.4
分享一个v0.10.31：http://yunpan.cn/cwqtqY8FCpdZc 访问密码 951e
下载好之后，双击安装，一路next即可。

5. 安装Hexo

右击任意位置，选择Git Bash Here。执行命令：
npm install -g hexo，报错如下：

npm ERR! Error: shasum check failed for C:\Users\ADMINI~1\AppData\Local\Temp\npm
-30024-KDJHJzgP\registry.npmjs.org\hexo-cli\-\hexo-cli-0.1.6.tgz

莫非是因为被墙了？换国内镜像源试试。
npm config set registry="http://registry.cnpmjs.org"，
然后再次执行npm install -g hexo，成功！

6. 创建hexo文件夹

在任意文件夹下（如E:\hexo），打开Git Bash，执行命令：
hexo init，
Hexo 即会在目标文件夹建立网站所需要的所有文件。

7. 安装依赖包

npm install

8. 命令缩写

hexo generate = hexo g
hexo server = hexo s
hexo deploy = hexo d
hexo new = hexo n

9. 本地查看

执行以下命令：
hexo g，
hexo s，
然后到浏览器输入http://localhost:4000查看效果。
至此，本地博客已经搭建起来了，别人看不到的。

10. 部署到GitHub

10.1. 注册

GitHub官网：http://www.github.com

10.2. 创建repository

creat new repository，Repository name和自己的用户名相同。比如我的用户名为voidking，那么Repository name就填voidking.github.io。

10.3. _config.yml

编辑E:\hexo下的_config.yml，修改Deployment部分：

# Deployment
## Docs: http://hexo.io/docs/deployment.html
deploy:
  type: git
  repository: https://github.com/voidking/voidking.github.io.git
  branch: master

10.4. 部署

hexo d，执行该命令，报错：

1	ERROR Deployer not found: git

执行命令：
npm install hexo-deployer-git --save，再次执行hexo d,报错：

INFO  Deploying: git
INFO  Clearing .deploy folder...
INFO  Copying files from public folder...
warning: LF will be replaced by CRLF in hello-world/index.html.
The file will have its original line endings in your working directory.
......
*** Please tell me who you are.

Run

  git config --global user.email "you@example.com"
  git config --global user.name "Your Name"

to set your account's default identity.
Omit --global to set the identity only in this repository.

FATAL Something's wrong. Maybe you can find the solution here: http://hexo.io/docs/troubleshooting.html
Error: error: src refspec master does not match any.

    at maybeClose (child_process.js:756:16)
    at Process.ChildProcess._handle.onexit (child_process.js:823:5)

估计必须要先配置SSH，然后才可以上传文件。

10.5. GitHub之SSH key

1、设置Git的user.name和user.email
在第一次使用Git时，你需要告诉你的协同开发者，你是谁以及你的邮箱，在你提交的时候，Git需要这两个信息。具体通过以下命令设置：
git config --global user.name "voidking"
git config --global user.email "voidking@qq.com"
需要注意的是，这里的name随意，邮箱是你的联系邮箱，与github完全无关。
查看配置命令：
git config --list

2、生成SSH密钥
ssh-keygen -t rsa -C "voidking@qq.com"，按3个回车，密码为空。

Generating public/private rsa key pair.
Enter file in which to save the key (/c/Users/Administrator/.ssh/id_rsa):
Created directory '/c/Users/Administrator/.ssh'.
Enter passphrase (empty for no passphrase):
Enter same passphrase again:
Your identification has been saved in /c/Users/Administrator/.ssh/id_rsa.
Your public key has been saved in /c/Users/Administrator/.ssh/id_rsa.pub.
The key fingerprint is:
e6:9e:e7:ae:ad:ee:9f:f0:e5:6b:60:63:85:e8:cd:ae voidking@qq.com

在C:\Users\Administrator\.ssh下，得到两个文件id_rsa和id_rsa.pub。
需要注意的是，命令中的-C参数，后面跟的内容是注释。也就是说，内容随意，与github完全无关。

3、在GitHub上添加SSH密钥
打开id_rsa.pub，复制全文。https://github.com/settings/ssh ，Add SSH key，粘贴进去。

4、测试
ssh git@github.com，提示：

The authenticity of host 'github.com (192.30.252.128)' can't be established.
RSA key fingerprint is 16:27:ac:a5:76:28:2d:36:63:1b:56:4d:eb:df:a6:48.
Are you sure you want to continue connecting (yes/no)? yes
Warning: Permanently added 'github.com,192.30.252.128' (RSA) to the list of known hosts.
Hi voidking! You've successfully authenticated, but GitHub does not provide shell access.
Connection to github.com closed.

11. 再次部署

hexo d，根据提示输入用户名和密码，等待一会儿便成功了！
