HG - Hexo + GitHub + Travis CI = 自动部署博客实现

背景

这里不要背景，就是因为懒，还想高大上！

hexo博客搭建先看文章 ： 基于windows的实现 ！

HG - 当Hexo遇到Github，擦出了什么样的火花

---

声明

本文如果你在windwos进行自动化部署的话，请绕道！

windows下加密SSH key 的 id_rsa ，生成的文件解密不了，解密不了，解密不了！

上文，基于windows下进行hexo的实现，可以在本地测试与实现，但不适合于自动部署实现，原因上面已经说了。

环境

（1）平台环境

VirtualBox 安装 Ubuntu Server 16.04 

（2）Ruby 安装其中的 坑，坑，坑

官方安装配置文档：

按照这里配置就完蛋了 : https://github.com/travis-ci/travis.rb

这里也不是完蛋了，毕竟平台都不一样，我的是Ubuntu Server16.04 !!! 安装Ruby成功 ，使用 Gem安装Travis 报错，折腾了一天！

报错如下：

root@ubuntu:~# gem install travis

/* end */

（3）Ruby 安装推荐 - Ubuntu Server

Ruby相关环境安装脚本：

Batch scripts for Ruby production environment install on Ubuntu Server.

怎样安装就自己看上面的文档吧！提醒一点，测试下是否已经安装过curl 了！

测试是否成功 ：

yuan@ubuntu:~$ ruby -v
ruby 2.3.1p112 (2016-04-26) [x86_64-linux-gnu]
yuan@ubuntu:~$ gem -v
2.5.1

（4）安装 travis

成功如下：

yuan@ubuntu:~$ sudo gem install travis
[sudo] password for yuan:

（5）Hexo 配置安装 - 自己安装咯，步骤一样

重温 ：

1. 下载node.js 配置环境变量；
2. 安装hexo : npm install -g hexo-cli

---

配置Travis

（1）接入Travis CI

打开 Travis CI 网站，使用Github账号登录。将鼠标放在右上角的用户名上，点击Account选项，会显示github的项目。找到博客项目，点击前面带有 X 符号的按钮，开启travis支持。

自己玩玩吧

（2）新建配置文件

首先打开博客项目文件夹，在项目根目录新建.travis.yml配置文件。

$ cd 博客项目文件夹根目录
$ touch .travis.yml

（3）新建文件夹 .travis : 确保已经开启travis支持

yuan@ubuntu:~/doc/hexo/.travis$ mkdir .travis
yuan@ubuntu:~/doc/hexo/.travis$ cd .travis

（4）复制id_rsa 和 创建 ssh_config文件

yuan@ubuntu:~/doc/hexo/.travis$ cp ~/.ssh/id_rsa ./

创建 ssh_config 文件 ：

yuan@ubuntu:~/doc/hexo/.travis$ sudo vim ssh_config 
[sudo] password for yuan: 

Host github.com
User git
StrictHostKeyChecking no
IdentityFile ~/.ssh/id_rsa
IdentitiesOnly yes

（5）travis 登陆

yuan@ubuntu:~/doc/hexo/.travis$ travis login --auto
We need your GitHub login to identify you.
This information will not be sent to Travis CI, only to api.github.com.
The password will not be displayed.

Try running with --github-token or --auto if you don't want to enter your password anyway.

Username: LABELNET
Password for LABELNET: ************
Successfully logged in as LABELNET!

（6）加密操作

加密操作
在博客项目文件夹下对ssh的私钥进行加密

yuan@ubuntu:~/doc/hexo/.travis$ travis encrypt-file id_rsa --add
encrypting id_rsa for LABELNET/blog
storing result as id_rsa.enc
storing secure env variables for decryption

Make sure to add id_rsa.enc to the git repository.
Make sure not to add id_rsa to the git repository.
Commit all changes to your .travis.yml.

此操作会生成加密之后的秘钥文件 id_rsa.enc，删除id_rsa密钥文件(私钥不能随便泄露)。

你的travis 目前上已经出现了下面加密解密key :

（7）我的 .travis.yml文件

yuan@ubuntu:~/doc/hexo$ cat .travis.yml 
language: node_js

node_js:
  - '4'

branches:
  only:
  - master

cache:
  directories:
  - node_modules

before_install:
- openssl aes-256-cbc -K $encrypted_xxxxxxx_key -iv $encrypted_xxxxxxxx_iv
  -in .travis/id_rsa.enc -out ~/.ssh/id_rsa -d
- chmod 600 ~/.ssh/id_rsa
- eval $(ssh-agent)
- ssh-add ~/.ssh/id_rsa
- cp .travis/ssh_config ~/.ssh/config
- git config --global user.name "LABELNET"
- git config --global user.email "1406046087@qq.com"

install:
- npm install hexo-cli -g
- npm install hexo-deployer-git --save
- npm install

script:
- hexo clean
- hexo g
- hexo g

after_success:
- hexo deploy

---

基本架构

_config.yml 配置如下：

deploy:
  type: git
  repo: git@github.com:LABELNET/labelnet.github.io.git
  branch: master

最后

（1）待解决问题

实力坑 - Hexo - Next 主题本地不报错，TravisCI 无内容生成！！！

（2）和我相关的资料
