/*
This .scss loop will create "margin helpers" and "padding helpers" for use in your web projects.
It will generate several classes such as:

.m-r-10 which gives margin-right 10 pixels.
.m-r-15 gives MARGIN to the RIGHT 15 pixels.
.m-t-15 gives MARGIN to the TOP 15 pixels and so on.

.p-b-5 gives PADDING to the BOTTOM of 5 pixels
.p-l-40 gives PADDING to the LEFT of 40 pixels

一路过来也部署过3、4个Rails App了，其中也使用过mina等远程部署项目，但每次去部署新的App还是会遇到一些大大小小问题。最近和几个朋友正在做一个应用，在部署的过程中又被自己坑了~所以今天准备总结一下，方便自己未来的部署之路，也方便Rails新手学习使用。

#####环境说明 因为Linux的发型版太多，所以不能一一举例，经过自己的实践体验，发现Ubuntu可以更轻松的部署您的Rails App（个人看法，曾经在Centos下部署，遇到了好多坑）。所以该博文将基于以下的部署环境。

1. 操作系统：Ubuntu14.04
2. Rails：4.2.0
3. Ruby：2.2.1
4. Mysql: 5.6.22
5. Nginx: 1.8.0
6. Puma: 2.11.0
