加快Octopress国内访问速度

| Comments

Overview

本文最主要引自加快octopress国内访问速度Octopress加速Google字体渲染,以下内容是在这两篇博文的指导上结合自己实践经验的总结.

在github中搭建好了Octopress后,访问速度非常的慢,这是引文Octopress使用了Google API的CDN服务和Google Fonts.Google的CDN访问速度在国外的网络环境下是非常快的,但是在天朝,非常非常的慢,尤其是使用了https来访问.

于是,为了加快访问速度,我们只好把Google的web fonts缓存到本地的服务器并更改jQuery的cdn服务.

1.把jquery的cdn服务改成microsoft的

编辑文件 source/_includes/head.html 找到下图注释掉的部分,替换成

<!--<script src="//ajax.googleapis.com/ajax/libs/jquery/1.9.1/jquery.min.js"></script>-->
  <script src="//ajax.aspnetcdn.com/ajax/jQuery/jquery-1.9.1.min.js"></script>

2.缓存google fonts (将PT Serif和PT Sans缓存到本地)

打开 source/_includes/custom/head.html

<!--Fonts from Google"s Web font directory at http://google.com/webfonts -->
<link href="//fonts.googleapis.com/css?family=PT+Serif:regular,italic,bold,bolditalic" rel="stylesheet" type="text/css">
<link href="//fonts.googleapis.com/css?family=PT+Sans:regular,italic,bold,bolditalic" rel="stylesheet" type="text/css">

https://fonts.googleapis.com/css?family=PT+Serif:regular,italic,bold,bolditalic 以及 https://fonts.googleapis.com/css?family=PT+Sans:regular,italic,bold,bolditalic 中的内容复制到本地,并在 source/stylesheets 下新建pt_sans.css和pt_serif.css文件,文件部分内容如下:

}

注意,此处访问这两个链接可能需要翻墙. 新建一个目录 source/fonts 把字体解压缩到这个目录下.
