分享一键wordpress博客部署脚本（Linux+Lighttpd+php+sqlite3+wordpress）(源码带注释)

以前学别人写一键安装包的作品，带注释，喜欢的可以拿去参考： python版本：2.7

【脚本说明】

VPS服务器一键安装sqlite版本的wordpresss.附带配置环境(Linux+Lighttpd+php+sqlite3).
vps只要开着SSH服务。就能一键部署好wordpress！不需要FTP！不需要MYSQL！简单，轻盈。
适合小内存VPS(搬瓦工)或者访问量不高的个人网站,企业站。

【脚本特点】

自带wp静态插件和屏蔽谷歌字体插件。
支持wordpress自定义链接。
防止sqlite文件被下载。
支持绑定域名
关闭WORDPRESS自带WP-CRON

【支持环境】

Centos6x，Ubuntu12x

【源码】
